Kien Thai

Full-stack Engineer (.NET Core + TypeScript)

Versatile Full-stack Software Developer with 3+ years of experience across backend, frontend, and cloud infrastructure. Proven track record in system design, architectural decision-making, and delivering high-quality solutions that scale. Comfortable working with diverse technologies to solve real business problems.

Beyond coding, I stay curious about emerging technology trends and AI innovations. When I'm not building software, you'll find me exploring new music, practicing floral arrangement, or planning my next travel adventure.
