Full-Stack Engineer
building in high-stakes domains

I ship production systems end-to-end: TypeScript / Node.js backends, React and Next.js frontends, event-driven architecture, multi-cloud infrastructure. Current work spans a multi-tenant agentic SaaS platform, a live healthcare fintech with real payment rails, and two full-stack AI products. Also an MBBS student at the University of Ibadan — clinical training is what taught me why software in high-stakes domains must be reliable, measurable, and auditable.

Production Engineering Wave

2026 - Present

Four production systems shipped end-to-end in a single year: AuraHealth (voice-first emergency triage + Interswitch escrow, Enyata × Interswitch Buildathon entry), Voxtar (healthcare voice AI platform), Oncolens (edge-native pathology AI via Knowledge Distillation), and a distributed biometrics proctoring backend (Go + gRPC microservices). Plus an ongoing contract on a multi-tenant agentic SaaS platform for US businesses.

Medical Studies (MBBS)

2019 - 2027

Bachelor of Medicine, Bachelor of Surgery at the University of Ibadan and University College Hospital. Clinical training in a high-stakes production environment — where software failures have direct human consequences — directly informs how I design systems for reliability, resilience, and responsible deployment.

The
Recharge

Five things bring me back to work sharper than I left. A long jog before a hard problem reliably unsticks it — a run clears my head faster than any productivity technique I've tried. Slower walks serve a different purpose: they're where the half-formed ideas get their edges sanded down. Uninterrupted reading resets attention. Deep conversations with friends over ideas worth arguing about keep my thinking honest. And coding for its own sake, without a deadline attached, is still the thing that started all of this.
