My name is Mighty Odewumi (known online as gr1ntch), a mobile and full-stack engineer based in Nigeria. I build React Native and web products for founders who need to move fast without rebuilding things twice.

My work spans product thinking, clean architecture, and security-aware implementations. I also perform UX and code audits on live apps to surface issues internal teams may miss.

Notable project

• Cosmos Wars — a physical-digital NFC collectible game where metal coins unlock characters in a mobile battle arena. I’ve built the prototype and core systems across the full stack: mobile client, game server, animation layer, and NFC integration. The prototype (auth, room creation, room joining) helped move the client into full production development.

Community & leadership

I led the Web Development track at Google Developer Groups OAU for a year, running workshops for 100+ attendees and mentoring students on real-world project delivery.

If you're building a mobile product and need an engineer who understands what founders actually need, I’d like to hear about it.
