The Build Log

I don't pitch.I ship.

Four years of building products, systems, and companies, from zero to real revenue. Here's the proof.

The Builder

I don't do decks. I build.

I'm Gbeke, a backend and AI engineer, and cofounder of products that run on real users and real money. For four years I've taken ideas from first commit to revenue: payments, AI agents, and the operational systems underneath them. Today I'm also an engineer at Kora, helping keep Africa's payment rails reliable.
