About

Not a portfolio developer.
A systems builder.

I'm Temitope Fawehinmi, a senior full-stack and backend engineer based in Lagos, Nigeria, with 8+ years building the systems that run real operations. My work sits at the intersection of backend reliability, workflow automation, and applied AI. Not demos, not tutorials. Production systems under real load.

My architecture has processed over 8,000 attendee check-ins across 12+ events, including a peak of 1,800 in a single afternoon without a single timeout. I've delivered the technology backbone for six major national and international summits, from Afreximbank's Annual Meetings to Invest Lagos 3.0, with zero technology failures across all of them.

The pattern across everything I build: take a fragile, manual, human-dependent process and replace it with a system that enforces quality, speed, and transparency on its own. Operations that run themselves.

I use Claude Code and GPT Codex daily as thinking partners, not code generators. I own every decision. I test before shipping. I review every line.

Available for senior remote roles (backend, full-stack, automation, applied AI) and consulting engagements. Dollar-market. Lagos cost base.

Secure Event Media Delivery at Scale

Oaken Gallery is a secure media delivery platform I architected end to end. The core constraint: per-client bcrypt auth so no client can ever see another client's photos. Projects, galleries, albums, clients. Organizers upload once. Clients self-serve. No manual downloads. No data leaks.

Insights
"Operations that run themselves."

Everything I build ladders up to one outcome: removing fragile, manual, human-dependent work and replacing it with systems that enforce quality, speed, and transparency on their own.

I write about the intersection of backend engineering, workflow automation, applied AI, and emerging AEO/GEO. The gap between what most developers build and what high-stakes operations actually need.
