Hi, I'm Abdul-muizz Hamzat

Fullstack Engineer & System Architecture Lead Abuja, Nigeria · WAT/UTC+1 · Full overlap with Europe (CET)

I architected the support system rebuild at Alleybookings that cut payment-related tickets 73%. I own the architecture of Giftagoal (crowdfunding) and Blacktherapy (therapy booking — migrated from WordPress to Next.js). Currently building Carepadi (elderly care healthtech) and Flewa (invoice mobile app) from the ground up.

I work across modern web, mobile, and Web3: fintech infrastructure, product architecture, and onchain tooling. Open to remote roles with EU, UK, and US East Coast teams.

AI-augmented workflow — GitHub Copilot for in-editor completions, Claude for architecture decisions and code review.
