About

Full Stack Developer with around one year of professional experience building real-world web and mobile applications. I enjoy turning ideas into reliable products, exploring AI and automation, and continuously sharpening my craft through collaboration.

Currently I'm a Full Stack Developer at RYNAN Technologies Vietnam, shipping internal platforms and mobile apps for industries ranging from rubber production to tourism and agriculture in the Mekong Delta. Outside of work I keep building side projects to try out new ideas — usually around real-time systems, microservices, and AI-powered features.
