What I'm looking for

I'm looking to bring speed and precision to a trading platform, building responsive, accurate interfaces for real-time, data-intensive financial experiences.

I've shipped five production React and TypeScript applications as an independent developer, turning wireframes into reliable interfaces with zero critical downtime. My work has reduced page load times by 40% and data-fetch latency by 35% through code-splitting, caching, REST API redesign, and optimistic UI updates.

I build responsive, data-heavy products such as NetPay, a real-time net-pay calculator, and Brother Money, an offline-first personal finance app. I also own end-to-end delivery across frontend architecture, Node.js backends, CI/CD, and Vercel deployments, and previously improved programming outcomes and IT workflows at the University of Iringa.
