About Me

Engineering reliable software, end to end

I specialize in building scalable web applications with a strong foundation in both frontend design and backend engineering.

I'm a full stack web developer who loves turning complex problems into simple, elegant solutions. My background spans teaching modern web development and shipping production systems — from online ticketing platforms to enterprise Point of Sale applications.

I care deeply about clean architecture, maintainable code, and squeezing every bit of performance out of an application. Whether I'm designing a database schema, crafting a REST API, or polishing a UI, I aim for software that feels fast, secure, and effortless to use.

I am 37 years old. Originally from Myanmar, based in Bangkok, THAILAND.

Experienced full stack web developer with strong backend expertise.

Passionate about clean architecture and performance optimization.

Built enterprise systems, RESTful APIs, dashboards, and POS applications.

Comfortable working independently and collaborating within teams.

Continuous learner who enjoys adopting modern technologies.

Focused on fast, secure, and user-friendly software.
