Zin Min Htun
Senior Full-Stack Developer7+ yearsDa Nang, Vietnam
Hi, I'm Zin Min Htun (Wine Chanz)
I'm a full-stack developer with 7+ years of experience: the last three in fintech and payments, and before that commerce software for businesses in Myanmar and around Southeast Asia — online shops, restaurants, warehouses and money changers.
Most recently I was Front-End Team Lead at Joy, a payments company (2023–2026), and took on the back-end team as well in 2024, while still writing much of the code myself. Before that came Anbuchi, co-founding Compass, and client work at Circles X on Zay Sine, COSCO and Digi-M. I've lived in Da Nang and worked fully remotely since 2023, and I'm available immediately.
2023–2026
Front-end team lead at Joy (fintech, remote); led the back-end team too from 2024.
2023–2024
Senior front-end and mobile developer at Anbuchi (fintech, part-time).
2022–2023
Co-founder and lead developer at Compass: e-learning and delivery apps.
2020–2023
Full-stack developer at Circles X: Zay Sine, COSCO, Digi-M; mentored juniors from 2022.
2017–2020
Intern at Zwenexsys International; static websites at Innovative Technology.
2014–2019
B.C.Sc., Computer Science, University of Computer Studies, Yangon.

Kind Words
creative portfolioNotes left by the firehrteherthrth
He doesn't just write code — he thinks in systems.
We brought him in to rescue a stalled e-commerce migration, and within three months he had rebuilt our checkout flow, cut page load times by 60%, and mentored two junior devs into confident contributors. He doesn't just write code — he thinks in systems.
He always delivers a little more than what was scoped.
Working with him is what every PM hopes for. He asks the right questions before writing a single line, flags risks early, and always delivers a little more than what was scoped. Our POS platform shipped two weeks ahead of schedule because of his planning.
Few have matched his ownership mindset.
In eight years of managing engineers, few have matched his ownership mindset. He took our warehouse management module from a fragile prototype to a production system handling 50,000 daily transactions — and documented everything so the team could maintain it without him.
He translates business goals into architecture.
As a non-technical founder, I needed someone who could translate business goals into architecture. He designed our entire MERN stack from scratch, explained every trade-off in plain language, and built a product our investors called 'remarkably polished for a seed-stage company.
Deployments went from stressful to boring.
His code reviews made our whole team better. He has that rare combination of deep Next.js expertise and genuine patience — he'd rather teach you why something breaks than just fix it silently. Deployments went from stressful to boring after he standardized our CI/CD pipeline.
