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.

• 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?
In 2014, the CBN launched BVN.
At the time, it looked like a regulatory compliance exercise.

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