Indie Developer · Hong Kong
Electrical + Software + IT Engineer
Expert in R&D. I design and build hardware and software end to end — from the circuit board to the cloud — and ship the result.
About
I’m an electrical engineer with software skills, based in Hong Kong.
For years I’ve worked across the whole stack — circuit boards, firmware, mobile apps, web services and the servers behind them. I like problems that don’t respect the line between hardware and software, and I take them from idea to a working, shipped product.
Today I build and ship under Lampstand Technology: live apps like ImageCal, an AI phone service called Ringly, and more in progress. I also take on technical solutions for hardware or software projects.
Selected work
A mix of rehabilitation hardware, IoT, and shipped apps — each taken from concept to a real, working device or product.
A wearable hand-rehabilitation exoskeleton that reads the wearer’s own muscle signals (EMG) and helps drive the motion — so patients recovering from stroke or hand injury can retrain real movement, guided by their own intent.
A smart mat that quietly weighs your pet whenever they step on it, then logs the trend to a cloud app — wrapped in a warm, illustrated interface that makes everyday health tracking feel friendly rather than clinical.
A wheelchair training and assessment simulator: a powered platform and ramp paired with a live on-screen dashboard, so therapists can run and measure mobility exercises in a safe, repeatable setup.
Snap a photo of any invitation, flyer or handwritten note and ImageCal pulls out the event and drops it into your calendar — the GPT-5 vision project that finally crossed the accuracy line worth shipping. Live on iOS and Android.
Writing
Build stories and how-tos on AI, apps and hardware.
Say hello
I provide technical solutions for hardware or software projects — from a quick question to a full build. Tell me what you’re working on.
