@TosinOlugbenga The scary part is many teams only realize they need reconciliation after the first money mismatch incident.

Stop designing APIs like internal tools.
External consumers will break your assumptions immediately.
If your API needs “tribal knowledge” to use, it will fail at scale.
We learned this after onboarding 3 clients and rewriting the same endpoint twice.
What's the one assumption your API made that external consumers immediately broke?

There’s also a weird paradox now:
AI lowers the cost of building products while simultaneously increasing the operational cost of being a power user.

Ngl, ai agents now cost more than hiring an actual developer if you're a heavy user. There's also so many choices to pick from now and it's all enticing.

@tomilola_ng Nice,
but backend is never done, talk less of being dusted

@CodeNomadly I learned Linux halfway through my career after struggling to find that UI. Never going back.
It was the sysadmin at my day job who got me hooked when he saw me struggling. I don't memorize much, just what I need and the rest is in the man pages.

@Plebian_2 @Akintola_steve That is the coordination problem it solves, being able to generate unique ID's in each system without needing a central system.

@CodeNomadly @Akintola_steve UUIDs don't solve anything, they only make collisions statistically improbable.

@smartnakamoura This is why many early-stage fintechs partner with licensed providers first instead of immediately pursuing full licensing themselves.

You want to build fintech in Nigeria.
Before you write a single line of code, here’s what CBN will ask you for:
- CAC registration
- MLRO appointment letter
- AML/CFT compliance policy
- Source of funds documentation
- Technical architecture review
Most founders find this out after building.
Save this.

How a Nigerian fintech gets licensed - simplified:
Tier 1 (Switching & Processing): ₦2bn capital — you process transactions between banks
Tier 2 (Mobile Money Operator): ₦2bn — you hold customer funds, issue wallets
Tier 3 (Payment Solution Service): ₦100m — you process payments but don’t hold funds
Tier 4 (Payment Solution Service Provider): ₦50m — you build on top of licensed entities (this is most startups)
Most Nigerian fintechs operate as Tier 4.
They never touch CBN directly. They plug into licensed processors like Interswitch or NIBSS.
The regulation complexity is real — but it’s navigable once you understand the layers.
Save this.
