Who I am

Developer &
problem solver

Hi! I'm Khamfai Sialimoua — a back-end developer and IoT enthusiast who loves solving real-world problems through code and connected hardware.

I specialize in JavaScript / TypeScript and frameworks like Elysia, Express, and NestJS, with databases such as MySQL and Couchbase and ORMs like Prisma and Sequelize. On the IoT side I work with C++ and Python to build embedded, connected systems.

I've collaborated with the Institut de Recherche pour le Développement (IRD) on soil-science and water-monitoring devices. Outside of work, I recharge by traveling and gaming.
