MMH POS

Independent full-stack project · Android and Windows

Burmese-first retail software for Myanmar SME shops, connecting product units, quantity-based pricing, credit sales, returns, inventory and staff permissions. I build the Flutter client, NestJS backend and data layer.

Experience

Professional experience

Innovation Link

Software Developer Intern · 2025–2026

  • Built responsive company website pages with HTML and shared CSS, then checked and fixed interface issues after deployment.
  • Connected LINE webhook messages with Gemini using Python and FastAPI for text and image responses.
  • Worked on message routing and rich-menu behavior, and reorganized backend code into modules.
A debugging example

Text requests worked, but image messages failed. I traced the message flow, corrected the image request handling and retested it. That experience taught me to verify each input path instead of treating one successful response as proof that the whole integration works.

Earlier work

University projects and research.

Smaller projects from my studies, and the research I led.

Hotel Booking App

University group project · Flutter

A Flutter prototype of a hotel guest check-in flow. Guests sign in with a booking ID, review their reservation, complete a check-in form, upload identity documents and a selfie, and receive a confirmation. The screens use sample data rather than a live booking service.

Airport Pickup FAQ Assistant

University group project · 2024

A web prototype for international students arriving at the university. A chat window uses the Gemini API to answer common airport-pickup questions, such as pickup times and meeting points, and a form lets students request the pickup service.

Research

Blockchain for Economic Stimulation

Academic research · Rangsit University · 2025

A survey study of how students view three blockchain features for public stimulus payments, using Thailand’s 10,000-baht digital wallet scheme as the case. Programmability and fraud prevention were linked with higher perceived effectiveness; accessibility concerns with lower.

About

The person behind the work.

Black-and-white portrait of Kyaw Wunna Htun looking down, against a dot-pattern background

I’m a software developer based in Bangkok and a graduate of Rangsit University. I work across interfaces, APIs, and data, with a particular interest in backend and full-stack engineering.

My approach starts with understanding the workflow: what someone needs to do, how information changes, and where things might go wrong. I enjoy working through the logic behind a system and refining the details that make an application easier to use and maintain. Understanding the problem is an important part of how I decide what to build.

I’m naturally curious about how things work and enjoy learning about unfamiliar domains. Alongside my development work, I’m exploring how AI can add useful capabilities to applications while deepening my understanding of the technology behind them.

Outside development, I enjoy photography, graphic design, and video editing. These interests shape how I think about composition, clarity, and how information is presented—an attention to detail that also carries into my software work.
