I build the systems behind products that have to stay up.

React / Next.js / TypeScript / Node.js / Flutter / PHP Laravel

Three years of shipping production web and mobile software, from schema design and API work through to the interface and the deployment pipeline. At Kofa Technologies I build frontend applications for a battery swapping network running in live African markets.

What I do

One engineer, the whole stack.

Most of my work spans the layers that usually get handed between people: the schema, the API, the screen and the pipeline that deploys all three.

01

Frontend engineering

Responsive React and Next.js interfaces wired to live APIs, with state that survives complex data flows. Figma handoffs translated component for component.

02

Backend and APIs

REST services, relational schema design, async workers and retry handling, in Node.js, NestJS, FastAPI and PHP (Laravel).

03

Mobile

Flutter apps built beside the web frontend and sharing its backend, so one change lands in both places.

04

Deployment and observability

CI/CD pipelines, containerised builds, AWS and Vercel deployments, and metrics wired in before launch rather than after the first incident.
