Software Engineer & CTO transforming operations with full-stack systems across web and fintech.
KenyaWhat I'm looking for
I’m a Software Engineer & CTO with 2+ years of experience delivering full-stack, production-grade systems—especially where reliability matters. I’ve debugged complex financial modules, migrated critical settlement logic, and improved operational efficiency, including achieving 99% uptime and reducing manual farm data entry by 50%.
In recent roles, I migrated Laravel to Elixir for a Stanbic settlement feature in under 6 weeks, built a high-concurrency Toll System MVP in less than 4 weeks, and ran Red Team / Blue Team testing simulations with strict deployment gates. I also led engineering strategy and a cross-functional team at AquaGen, and developed a mobile-first React eCommerce platform with M-Pesa payments, scaling to 150+ daily orders while setting DevOps standards for dependable delivery.
