Software Engineer. System Design. Sharing what I learn so you don’t have to Google it twice. Startups, let’s build. Growth is the Real Stack.

Many football fans are going to sleep at work today 😭

24hrs doesn’t last again

@SherlockHom221B No go punch your screen ohhh 😹

When does it matter most?

• APIs with high concurrency
• Apps with many short DB queries
• Any service under consistent load

If your DB is a bottleneck, connection pooling is usually one of the first things to check.

Don't rebuild cars. Reuse them.

One small change that dramatically reduced our API response time:

Connection Pooling.

Here's what it is and why it works 🧵

[Pasky The Software Engineer @pasky_u]

Popular tools:

• PgBouncer: for PostgreSQL
• HikariCP: for Java/Spring apps
• Sequelize / Knex: built-in pooling for Node.js
• SQLAlchemy: pool support in Python

PS: Most ORMs support pooling out of the box. Check your config.

Tech money is not ASAP money.

That mindset is misleading a lot of new devs.

Some people start earning in a few weeks. Others take over a year. It's not really about time, it's about skill, clarity, and how well you position yourself.

If you enter tech expecting instant results, you'll quit before it gets good.

Focus on becoming valuable. The money follows.

What's one thing you wish someone told you before you started?

No-code tools did not replace software engineers.

They just created a new category of bugs that software engineers now get paid to fix.

In 2014, the CBN launched BVN.

At the time, it looked like a regulatory compliance exercise.

Eleven years later, the Bank Verification Number has become one of the most consequential pieces of technical infrastructure ever built in Nigerian financial history.

And most engineers who use it daily have never thought about what is actually happening underneath.

How senior devs carry their laptop

[Pasky The Software Engineer @pasky_u]

@Dev_JesseMaduka @davveeystickzz Because renaming a table is never just renaming a table. 😹

[Pasky The Software Engineer @pasky_u]

Might be unrelated but most times They hire great engineers using intense system design and technical interviews, but onboarding them into a broken codebase with zero documentation, bad work culture, and chaotic management.

You can’t filter for the best talent and then give them a frustrating environment to work in and expect them to stay.

[Pasky The Software Engineer @pasky_u]

Writing code is only half the job. As you scale into senior roles, your primary output shifts from lines of code to developer enablement. If you can't mentor junior developers, communicate architectural trade-offs to business stakeholders, or build team alignment, your impact hits a hard ceiling.

[Pasky The Software Engineer @pasky_u]

People confuse highly publicized with saturated. Nigeria's economic landscape is massive and highly informal. Until fintech seamlessly integrates into the day-to-day operations of every MSME and informal trader without friction, the market is wide open.

[Akintola Steve @Akintola_steve]

A good reminder that Nigeria’s Fintech space is nowhere near saturated.

We haven’t even covered a fraction of what the market needs yet.

Don’t let anyone discourage you.

Keep building. There is still a lot of room to create.

[Pasky The Software Engineer @pasky_u]

It’s so sad that someone earning 100k to 150k in Nigeria is still struggling.

[HER❤️ @Chiziterem_x]

Nigerian organizations with 100k and 150k salaries
I don tire mehn!

[Pasky The Software Engineer @pasky_u]

The job market. Most people don’t work for passion anymore. They just want to survive.

[Ray 👨🏽‍💻 website & app developer @Raynerdtech]

How many people are actually working in the exact field they studied in school?

It feels like everyone I know graduated in one thing and ended up building a career in something completely different.
