Now building Vision Center at Walmart

Hey, I'm Min.
I build Android apps.

Min Phone Nyunt WinAndroid Software EngineerKotlinJetpack Compose

For 10+ years I've built apps that millions of people open every day: mobile money, banking, the 7-Eleven app, and now Walmart Health & Wellness. I care about clean architecture, tests that catch real bugs, and releases that go out on time.

// about

A little about me

I started in 2016 building apps and 2D animations in Adobe Flash (yes, really) in Myanmar. Then I found Android and never looked back. Since then I've worked on mobile money, digital banking, a big US bank, the 7-Eleven app, and now Walmart's Vision Center.

My happy place is a codebase that's easy to change: small modules, clear MVVM layers, and tests written first. I also use AI coding tools every day, because nobody should hand-write boilerplate in 2026.

After work I swap Kotlin for stock charts. I'm a long-term value investor, I'm learning trading on the side, and I like investing in real estate too.

The rest of the time you'll find me reading a book, cooking (sometimes), binge-watching a movie or a good series, or traveling with friends. I also make short videos about great books.

And yes, I bleed blue. I've been a huge Chelsea FC fan since I was 6, the year I discovered football.

Kind words from people I've shipped with

“A tremendous asset to my team.”

Min Phone Nyunt Win is an excellent resource and a master at Android development. His focus keeps everything moving smoothly, he makes sure all the deadlines are met and makes sure that whatever project he is working on meets the highest standards.

Muhammad WaseemHead of Transformation, fintechManaged Min directly · 2021

“Amazingly high quality and fast.”

His ability of developing an Android app is amazingly high quality and fast, not to mention his additional skill to write unit test and thinking on App Architecture… He can point out the flaws that I hadn’t spotted in the Backend.
