Backend engineer based in Lagos, Nigeria with 4+ years building financial infrastructure in Go. I work on systems where correctness isn't optional — loan collections, payment processing, and remittances that real people depend on.
Currently at FairMoney, where I'm building FairMoney Collect: a field collections platform for agents working across Nigeria, including GPS-verified visits, offline-first action queuing, and live loan data from upstream core banking systems.
Before that, I led a 2-week GBP payment system migration for a UK bank — 10-person team, zero downtime, £50k+ in savings. That kind of deadline sharpens you.
I believe software engineering is a craft. I write code that the person after me can read, systems that the on-call engineer can debug at 3am, and PRs that explain why, not just what.

}| Project | What it does | Stack |
|---|---|---|
| FairMoney Collect | Field collections platform for 45+ agents — offline-first, GPS-verified visits, live loan data | Go, AWS, PostgreSQL |
| FlexiCredit | Overdraft and credit system at FairMoney — event-driven transaction handling, interest calculation, and accrual visibility for millions of users | Go, AWS SQS, PostgreSQL |

A few things I care about as an engineer:
Ownership. I don't hand things off at the PR boundary. If it's in production and it breaks, that's still my problem to understand.
Clarity over cleverness. The most elegant solution is the one the next engineer can reason about without asking me. I write code and PRs accordingly.
Zero incidents is a decision, not luck. Two consecutive quarters, no production incidents across FlexiCredit, Loan Collections, and FairMoney Collect. That's not magic — it's deliberate thinking about edge cases before they become 3am pages.
Mentorship compounds. I've mentored 50+ women remotely and teach weekly in-person software classes to secondary school students from low-income backgrounds in Lagos. The craft grows when you share it.
