About
Bridging software and hardware, with a focus on real-time UX.
I'm a full-stack engineer with over four years of experience shipping mobile, web, and desktop software. My work sits at the intersection of app development and embedded hardware — Flutter clients talking to BLE peripherals, Node.js services driving devices over TCP/IP, and streaming pipelines that have to feel instant.
At Digital Core Technologies, I build end-to-end products alongside hardware and firmware teams — from pairing flows and command protocols to performance tuning and reliable connectivity. I care about responsive interfaces, predictable state, and code that's kind to whoever reads it next.
