About

Full-Stack Software Engineer with over 5 years of hands-on experience.

I am a Full-Stack Software Engineer from Myanmar, currently based in Vietnam. I started my journey in technology through computer science studies in 2015 and have since built web applications, internal tools, and software solutions across freelance and professional environments.

My work focuses on practical full-stack delivery, maintainable systems, and solutions tailored to real business needs. This portfolio highlights the experience, projects, and technical skills that reflect that journey.
