Who I am

Results-driven builder with a habit of turning complex, ambiguous problems into clean, scalable software.

Sanusi Emmanuel Femi

Results-driven Full-Stack Developer with 3–5 years of experience building production-grade web applications, AI-powered tools, blockchain integrations, and automation systems. I've delivered 10+ real-world projects across e-commerce, fintech, Web3, and SaaS using Python, Django, React, TypeScript, and Node.js.

I'm known for diagnosing complex bugs fast, integrating third-party APIs cleanly, and shipping on time — whether that's a WhatsApp consultation bot serving clients 24/7, a Hedera blockchain dApp, or a Shopify store race-condition fix at 2am.

Currently pursuing a B.Sc. in Computer Science at the University of Ibadan (expected 2026), and open to remote freelance work and full-time engineering roles.
