About

Raymond Tse — Software Engineer

I'm a full-stack software engineer and Web3 developer based in Abuja, Nigeria, available for freelance contracts and full-time roles (remote or on-site). I build production apps with React, Next.js, TypeScript, Node.js, Solana, and AI APIs — from fintech and health tech to crypto trading platforms and embedded systems.

I've shipped 10+ products end-to-end: NAIJA GPT (AI football app on Play Store), Boom Tech (lender comparison), BetJuju, PayParrot (fintech + AI), AdhereWell (health), PocoTask, Verstronet (embedded hardware), and more. I focus on clean architecture, fast delivery, and code that teams can maintain.

Open to work: full-stack, frontend, Web3/blockchain, AI engineer, and embedded systems roles. Hire on Upwork, Fiverr, or direct contract here. LinkedIn · Resume.
