Hussein Tijani

Profile

Industrial chemist turned builder, working where software meets money. I'm an account officer at GTBank, handling account and KYC documentation, treasury bills, loans, trade facilities and Form M. Alongside that, I build production web products end to end with Next.js, TypeScript, Supabase and Paystack, including a live multi-sided marketplace, client websites, AI document agents and paper-trading systems. I'm detail-oriented and process-disciplined, with a background in laboratory and HSEQ compliance.
