There are DevOps Engineers better than me who will never get the opportunities I've gotten.

Not because they're bad. They're brilliant. They just chose to stay invisible.

Let me be honest. In over 6 years of engineering, I have never once job hunted. Every role came from two places: a recruiter found me on LinkedIn, or someone I'd worked with recommended me.

That's not luck. That's visibility.

This current tech market rewards visibility almost as much as skill. And no, visibility doesn't mean becoming an influencer.

A lot of engineers still think: "Once I learn enough, opportunities will come." That era is dying. Today, people hire people they see. People they trust. People they remember.

Silence is expensive now.

Here's the painful truth:

Engineers are posting "no jobs in tech" while recruiters literally can't find them anywhere online. No GitHub activity. No technical discussions. No projects shared. No presence. No proof of work.

You can't be discoverable while hiding.

Visibility is no longer optional. Especially now that AI can help everyone write code.

Your edge is no longer "I can write Terraform modules." Your edge is: How do you think? How do you solve problems? How do you explain complex systems? What have you actually built?

The engineers winning right now are documenting everything.
Not because they know everything. Because documentation compounds.

One post about a Docker memory leak today. One pipeline debugging thread tomorrow. One architecture breakdown next week.

Six months later? People think you're everywhere. Recruiters find you. CTOs remember your name.

I started sharing my work publicly. Not polished tutorials. Just real problems I solved at work. Real mistakes. Real lessons.

That's when everything changed. Consulting requests came. Mentorship bookings increased. Speaking invitations landed.

None of that happened because I became a better engineer overnight. It happened because I made my existing skills visible.

You're already solving hard problems at work. The only difference between you and the engineer getting opportunities is they're sharing what they learn. You're keeping it in private Slack channels where it dies.

Start small. One post this week. Share one problem you solved. You don't need to be an expert. You just need to be visible.

Your skills got you here. Visibility will take you where you want to go.

What's stopping you from sharing your work publicly?

This message came in from a mentee earlier this week.

"Hello brother Blaise. I finally succeeded to pass the issue yesterday and connect the compiled front end to the backend server 😁😁 I was so so happy 🤣🤣🤣"

Here's the backstory.

He'd been stuck for two days on a Node.js deployment to Azure App Service. The app was failing at startup — a fix-prestart.js script throwing MODULE_NOT_FOUND because it was trying to load ts-node binaries in a path that only existed in the dev environment, not in the compiled production build.

He sent me the Azure log stream. The VS Code screenshot. The current error. The AI suggestion he'd tried that didn't work. He wanted me to tell him what to do.

I didn't.

I asked him one question: "Walk me through what the prestart script is actually trying to do."

He started explaining. Midway through his own explanation, he paused.

"Wait. Why would a compiled build need ts-node at runtime? The TypeScript is already compiled."

There it is.

"So maybe I should remove the prestart step from the production config entirely?"

That's it.

He fixed it the next morning.

That message — the happiness in those laughing emojis — wasn't just about a deployment working. It was about the moment an engineer realizes they had the answer inside them the whole time. That the debugging process they just ran was theirs. That they can run it again next time, on a different problem, with nobody's help.

That's what I'm trying to build in every mentee. Not dependency on me. Confidence in themselves.

The answer I give you today is forgotten in a week. The thinking process you build yourself lasts a career.

If you want to be mentored this way — I have a spot opening next month in my mentorship program.

DM me "mentor" and I'll send you the details.

An engineer reached out to me last year.

Three years at the same company. Clean code. Never missed a deadline. Technically better than some of the seniors on his team.

Passed over for promotion twice.

He was frustrated. Almost ready to quit and find a senior title somewhere else — which honestly, is what most engineers do when they hit this wall.

He asked me:

"Blaise, what am I missing? My code is better than half the seniors here. What do they have that I don't?"
I told him the truth.

It was never the code holding him back.

Most engineers think getting promoted to senior is about writing better code.

So they study harder. Learn new frameworks. Work longer hours hoping someone notices.
And they stay stuck.

Because the people making promotion decisions are not asking "can this person write good code?"
They are asking: "Can this person be trusted with more?"

That is a completely different question.

Here is what actually separates mid-level from senior:

Ownership. Mid-level closes the ticket. Senior closes the ticket, watches the metrics, writes up what happened, and fixes the root cause. Same fix. Different level of responsibility.

Proactive communication. Mid-level mentions the blocker on Friday when the deadline is already at risk. Senior surfaces it Wednesday — with context and options. Same problem. Completely different impact.

Systems thinking. Before any significant change, they ask: who depends on this? What breaks if I get this wrong?

Making people around them better. Reviews that teach. Showing up for the junior engineer who is stuck. They raise the floor of the entire team.

We didn't touch his code at all.

Four months after working on these four things — he got the promotion.
Write good code. But think like someone the team cannot afford to lose.

Where are you on this journey right now? Tell me in the comments.

This week's newsletter breaks it all down with real examples. Link in the comments. Every Sunday I write one email to thousands of engineers around the world. One topic. Real tactics. No fluff.

Choosing the wrong architecture early isn't a technical problem. It's an expensive one.

And I mean expensive in the way that keeps compounding every single day.

Here's what actually happens: wrong architecture doesn't make your app explode. It just makes everything you build afterward cost more. That feature you could knock out in two days with a simple setup? Now it's a week-long project spread across multiple services. Debugging something that would take an hour in one codebase? You're spending half a day tracing requests through five different systems.

The real pain is that the cost keeps stacking up. Every architectural decision you make early affects literally everything you build later. Went with microservices when a straightforward app would've worked? You're now paying the microservices complexity tax on every feature. Chose a database that doesn't match your data patterns? You're fighting that mismatch with every query.

Wrong architecture choices hurt in two ways. First, reversing them means rebuilding huge parts of your system. Second, living with them means development takes longer and costs more every single day.

The tricky part? Wrong architecture often looks perfectly reasonable when you're making the decision. Microservices sound scalable. NoSQL databases sound modern. Complex architectural patterns sound professional and mature.

But they're only the right choice when they actually match your needs. Your real needs. Not the ones you imagine you'll have someday.

Look, I get it. Planning for scale feels responsible. But here's what I've learned: choose architecture based on your current reality. Not where you think you'll be in three years.

A simple architecture you can evolve later beats a complex one you adopted too early. Almost every time.

You can always add complexity when you genuinely need it. The problem is, removing complexity you added prematurely is brutally hard.

Save yourself the pain. Start simple. Add complexity only when your actual problems demand it.

What architecture decision ended up costing you the most time?

An engineer DMed me on LinkedIn frustrated. They'd been working at their company for 2 years. Still not promoted to senior. They asked what they were doing wrong.

I asked: "What production incidents have you led in the last 6 months?"

They said: "None. I'm not on-call. Only senior engineers handle incidents."
There's your problem.

You can't become a senior engineer by avoiding the hardest parts of the job.

Incidents are where you learn what normal operations never teaches you. How systems actually fail. How to debug under pressure. How to communicate impact to non-technical stakeholders while you're still investigating.

These aren't skills you get from tutorials. You get them from being in the fire.

I told them: "Volunteer for on-call. Tomorrow."
They hesitated. "What if I mess something up?"

I said: "You will. Everyone does. That's how you learn. The difference between junior and senior isn't that seniors don't make mistakes. It's that they've made enough mistakes to know how to recover fast."

Here's what nobody tells you about becoming senior: you have to seek out the uncomfortable work.

Leading incident response. Being on-call. Debugging production issues you didn't create. Writing postmortems. Presenting to leadership about why things broke.

These are the experiences that compound into judgment.
I volunteered for on-call in my first 6 months at every company I've worked at.

Not because I loved getting paged at 2am. Because I knew that's where the learning happens. Every incident is a masterclass in how production systems break.

You learn what monitoring actually matters. You learn which alerts are useful and which are noise. You learn how to prioritize when multiple things are on fire. You learn how to explain technical problems to executives in two sentences.

The engineer who avoids incidents stays junior. The engineer who runs toward them becomes senior.
Three months after that conversation, the engineer messaged me again. They'd volunteered for on-call. Led 4 incident investigations. Got promoted.

Not because they suddenly became a better coder. Because they demonstrated they could handle production responsibility.
Here's my framework for accelerating to senior:

Shadow every incident even if it's not your service. Read every postmortem. Understand what broke and why.

Volunteer for on-call within your first year. Ask to shadow experienced engineers during their shifts before taking your own.
Lead at least one incident investigation per quarter. Don't just participate. Own the communication. Write the postmortem. Present the findings.

Certifications don't make you senior. Conference talks don't make you senior. GitHub stars don't make you senior.

Production responsibility makes you senior. Demonstrating you can be trusted when things are broken and users are affected.

If you're waiting for permission to take on more responsibility, you're thinking like a junior.
Senior engineers don't wait. They volunteer.

What's stopping you from being on-call?

Most people don’t struggle with LinkedIn because they lack value.
They struggle because they’re inconsistent.

They post once, disappear for weeks, overthink their ideas, and wait for the “perfect moment.” Meanwhile, others, sometimes less experienced, are building visibility, trust, and opportunities simply because they show up.

That difference compounds.

In today’s world, visibility is leverage.
It’s how founders attract clients.
It’s how freelancers get inbound work.
It’s how professionals get noticed by recruiters.
It’s how creators build influence and authority.

And the good news? It’s a skill you can build.

That’s exactly why I created the Linksched 30 Days LinkedIn Visibility Challenge.

From May 1 – May 30, the goal is simple: help you show up consistently, build authority, and turn your ideas into opportunities.

Inside the challenge, you’ll:

• Build a consistent posting habit
• Increase your profile visibility and engagement
• Position yourself as an authority in your niche
• Learn how to turn content into real business and career opportunities

And if your schedule is tight, you’ll also have access to a scheduling tool to plan your content ahead of time, so consistency doesn’t depend on free time.
Because one focused month of consistency can create momentum that lasts for the rest of the year.

Imagine ending May with:

More visibility
More confidence
More inbound opportunities

If you’ve been thinking about taking LinkedIn seriously, this is your moment.
Starts May 1. Limited slots available.

If you're in a senior system design interview and you're asked to design a caching strategy for an API serving 10 million requests per day, what questions about invalidation would you ask?

System design interviews for senior roles test whether you understand that caching is easy but cache invalidation is one of the hardest problems in computer science.

The questions you ask reveal whether you've dealt with stale data issues in production or just read about caching in blogs.

How often does the underlying data change and how stale can cached data be?

Designing cache for product prices that change hourly is completely different from user profiles that change daily. If users can tolerate seeing data that's 10 minutes old, aggressive caching works. If they need real-time data, caching becomes complex.

What happens when cached data becomes stale and users see outdated information?

For product recommendations, stale cache is annoying. For inventory counts during checkout, stale cache means selling products you don't have. The business impact of stale data determines your cache strategy.

How do we invalidate cache when the underlying data changes?

When a product price updates, do all cached entries invalidate immediately or do they expire naturally after TTL? Event-driven invalidation is accurate but complex. TTL-based expiration is simple but guarantees staleness.

What's the cache hit ratio we're targeting and at what cost?

A 99% cache hit ratio sounds great but if achieving it requires massive Redis clusters costing $5,000 monthly when a 90% hit ratio costs $500, is the extra 9% worth 10x the cost?

How do we handle cache warming and thundering herd?

When cache expires on a popular item, thousands of requests hit the database simultaneously trying to repopulate it. The database gets overwhelmed. Do we use cache warming, request coalescing, or probabilistic early expiration?

What happens when the cache layer fails?

If Redis goes down, do all requests hit the database and potentially overwhelm it? Or do we serve stale data from a backup cache? Complete cache failure needs a fallback strategy.

How do we debug issues caused by stale cache?

When users report seeing wrong data, how do you determine if it's a cache problem versus a database problem? Observability into cache hit/miss rates and data freshness is critical.

What questions would you ask?

Many smart people secretly feel behind.

Behind in career.
Behind financially.
Behind socially.
Behind in life.

What makes it worse is they rarely need more talent.

They need direction.

I work with people through 1-on-1 mentorship sessions, clarity calls, and growth consultations to help them stop spiraling and start progressing.

Because confusion creates delay.

And delay becomes frustration.

In our session, we can identify:

✅ What’s actually blocking your progress
✅ Which opportunities fit your strengths
✅ How to enter tech or level up in tech
✅ How to position yourself for better income
✅ How to build confidence again
✅ How to stop wasting time on low-value moves
✅ What your next 30–90 days should look like

This is for people who are ready for truth, structure, and momentum.

Not excuses.

Not endless talking.

Not fake hype.

Just real guidance built around you.

I’ve seen people change direction, gain confidence, get unstuck, and finally move with purpose after one powerful session.

Sometimes the right conversation changes everything.

If deep down you know you’re meant for more…

Listen to that feeling.

DM me “READY” or book a session today.

Start Here

You’re not behind.

You may simply need alignment.

Most people don’t have a visibility problem.
They have a consistency problem.

Every week I meet talented founders, freelancers, consultants, job seekers, and professionals doing great work… yet almost nobody knows they exist.

Not because they lack skill.
Not because they aren’t smart enough.
Not because the market is unfair.

Because they disappear.
They post once, then vanish for two weeks.
They overthink content.
They wait for the “perfect time.”

They watch less qualified people become more visible simply because those people show up.
That is exactly why I created the Linksched 30 Days LinkedIn Visibility Challenge.

From May 1 – May 30, we are helping ambitious professionals build one habit that changes careers and businesses:

Showing up daily with intention.

Inside this challenge, you’ll learn how to:

Build a consistent posting rhythm
Grow profile visibility and engagement
Position yourself as an authority in your niche
Turn attention into clients, recruiters, and opportunities
Stop lurking and start being seen

This is not theory.
This is ex*****on.

Because one strong month of consistency can create momentum that lasts the rest of the year.

Imagine where your brand could be by June if you start now.
More profile views.
More inbound messages.
More trust.
More relevance.
More leverage.

And the truth is simple:
If people don’t know you exist, they cannot hire you, recommend you, trust you, or buy from you.

Enrollment is only 5,000 XAF.

That is a tiny investment for a skill that can compound for years.
Challenge starts May 1. Limited slots available.

Join now and let this be the month people start noticing your work.
