I've built production interfaces for Diamond Trust Bank, Crowdbotics, AMPATH, and international product clients. My frontend performance work at Diamond Trust Bank cut crash rates by 99% and load times by 20% on live banking applications.

I build highly interactive TypeScript, React, and Next.js products, including real-time balances and notifications over WebSockets for applications carrying over $1M in transactions. I also own design systems, shared component libraries, dashboards, data visualisation, and responsive interfaces from design files through production.

At Crowdbotics, I built and maintained a shared component library used across client React and React Native applications and shipped 10+ production web and mobile apps reaching approximately 50,000 monthly active users. Earlier, I helped scale the AMPATH Point of Care clinical system to more than 100,000 HIV patients in active clinical use.

Through Isako Labs and freelance work, I lead remote delivery end to end across frontend features, backend services, integrations, and client communication. I also ship LLM features including streaming chat assistants, RAG on Supabase and PostgreSQL/pgvector, and prompt-regression evals.
