I build fast, polished software for people around the world — from native iOS and cross-platform mobile apps to Bluetooth Low Energy SDKs and developer tools. I care about clean architecture, smooth experiences, and the small details that make a product feel right.
I'm a software engineer based in Vietnam with a strong foundation in computer science and a decade-long obsession with building things that work beautifully. My work spans mobile development, Bluetooth Low Energy, and the developer tools that make hardware easier to talk to.
Over the years I've shipped consumer apps to millions of users, designed and maintained a production BLE SDK for Fossil & Misfit smartwatches, and led mobile work for a construction-tech platform. I move comfortably between native iOS, cross-platform React Native, and the back-end services that power them.
When I'm not shipping product, I write about iOS and BLE on my blog and build side projects like Signal Hub — a BLE toolkit that spans a macOS workbench and an iPhone companion app for testing Bluetooth devices. Tooling is where curiosity and engineering meet, and it's some of my favorite work.
“Good software disappears. It does exactly what you need, quietly, and gets out of your way.”
From embedded silicon to shipping mobile products — a path through the full stack of how software meets the real world.
A mix of products, SDKs, and developer tools — across iOS, Android, web, and macOS.
A BLE workbench for Mac — scan and connect to many devices at once, build visual automation workflows, simulate peripherals, and export PNG & video.
Control equipment and construction projects from one platform, with real-time insights and performance reports that maximize operational productivity.
A production Bluetooth Low Energy SDK letting apps communicate with Fossil and Misfit smartwatches and trackers — alerts, time zones, activity, and remote control.
A professional BLE toolkit in your pocket — scan and connect to peripherals, inspect bytes, stream live data in a terminal, and mock peripherals, all from your phone.
A fitness social app that connects users to personal nutrition coaches, crafts personal meal plans, and tracks progress with smart recommendations.
A daily guide to TV shows and events in Vietnam, with personal notes, editing, and notifications to never miss a program.
A marketplace connecting news hunters with media channels and newspapers to buy and sell breaking stories — across web and native mobile.
Solid CS fundamentals — algorithms, data structures, and design patterns — applied across the stack.
A browser IDE for creating projects and building, running, and debugging applications online across C/C++, C#, and Java. Developers post questions linked to their projects so the community can answer inline — no local IDE setup, and faster debugging through shared knowledge.
Have a project in mind, a Bluetooth problem to crack, or just want to talk shop? I'm always happy to connect.
