Hi, I'm Nyi Nyi Zaw
Lead Mobile Engineer
I've spent nearly a decade crafting mobile experiences that people actually enjoy using. From building secure fintech apps to healthcare platforms that connect doctors, I've worked across Android and iOS to solve real problems. I love diving deep into clean architecture, optimizing performance, and turning complex ideas into smooth, intuitive apps. Whether it's leading a team or coding late into the night with Kotlin and Swift, I'm driven by creating software that makes a difference. Currently leading mobile innovation at PassKit, and always excited about the next challenge.
