About Me
Full stack developer who finds joy in building complete, end-to-end applications that bring ideas to life.
Hello, I'm Zi-cheng Lin · Thaung Than Han
I’m a full-stack software engineer with over 3.5 years of professional experience building reliable, client-facing web applications. I have contributed to enterprise products for Japanese organizations and worked across frontend, backend, testing, and deployment.
I enjoy building products that solve real problems and create meaningful value for users. Alongside my professional work, I develop AI-powered applications, browser extensions, and open-source tools, with a strong focus on usability, reliability, and maintainability.
When I’m not coding, you’ll find me exploring new technologies, contributing to open-source projects, or enjoying a good cup of coffee. :D
