About Me

Jackson Wesanza

I build software because I believe technology should leave people better off than it found them — even if that just means one stranger's day getting a little easier.

I specialize in Full-Stack Engineering and Systems Architecture, focusing on multi-tenant SaaS platforms and East Africa-facing infrastructure like M-PESA and Africa's Talking. With 4+ years shipping production software, I build systems that hold up under real business load — not just demos.

I'm currently Lead Engineer & Co-founder at BinByte Engineering, where I split my time between backend architecture, mentoring, and product decisions. Outside of shipping, I keep deepening Go and ML/AI, and enjoy thinking about systems more broadly — from distributed architecture to the philosophy of mind.
