Chanchai Tasujai
Project Manager · Senior QA · Full-Stack Developer
I am a Lamphun native and currently live and work here. Starting as a Computer Teacher, I learned the art of knowledge transfer. Then, as a Software QA, I developed an eye for detail and quality. Advancing to Project Manager gave me a holistic view of business and management. Today, I merge all these experiences to walk the path of a Full-Stack Developer with a dream of having my own product. Although I may not be a deep-level code wizard, my strength lies in my passion for technology and leveraging modern tools—especially applying AI to multiply productivity.
