Scene 01The engineer

Owner of the whole stack, from ledger to launch.

I'm a lead full-stack engineer who owns systems end to end — data model, API, payment integration, interface, and deployment. I've led delivery of marketplaces, mortgage and housing platforms, ERPs, and health apps for clients across Kenya and the Gulf, integrating M-Pesa, KCB, JamboPay and SMS gateways along the way.

Model the money first. Ledgers, minor units, idempotent callbacks, and reconciliation are designed before a single screen.

Put the rules where they can't be bypassed: database policies, security-definer RPCs, and role-based access over client-side checks.

Write the specification, then ship against it, with tests, ADRs, and runbooks the next engineer can actually use.
