Backend-leaning Full-Stack Developer with 4+ years shipping production systems in fintech, fiscal-compliance SaaS, and real-time transport platforms across Nigeria, the UK, and Spain.
I build the parts of a product that are hard to get wrong: payment flows with idempotency and sub-account settlement, compliance integrations against live government APIs, state machines that enforce lifecycle correctness across distributed clients, and backend infrastructure that stays reliable under real traffic.
