PHP & Laravel Architect
With 7 years of hands-on software development experience, PHP and Laravel form the core pillar of my backend engineering career. I have built scalable multi-tier fintech savings engines (Flexi, Dollar, Group, Vault), LMS API integrations for automated certificate issuance, and multi-user Stripe checkout APIs for clients in Nigeria and Australia.
Alongside Laravel, I work heavily with NestJS, Node.js, Python (FastAPI), React, and Next.js — empowering organizations to replace expensive third-party SaaS vendors and own high-performing internal microservices.
