I build backend systems, mostly payments and fintech in Python. I came to software from accounting and capital markets, so I tend to care about money movement, correctness, and edge cases as much as the code itself.
- 🔭 Currently building backends with FastAPI and async PostgreSQL
- 🌱 Deepening my backend and open-source work (OSS contributions, hackathons)
- 💼 Open to backend/software engineering internships and open-source collaboration
- 🧠 Background: BSc Accounting, University of Lagos · Software Engineering coursework at AltSchool Africa (2022) · ex-ALAT by Wema (payments & developer relations)
