Who am I?

Embedded · Hardware · Infra · Open Source
I'm an engineer who works the full vertical — from laying out a PCB and writing driver code in C or Rust, all the way up to designing the case in FreeCAD and shipping the backend infrastructure that talks to it. I like owning a problem end-to-end and not stopping until the whole thing actually works.
A big chunk of my day job and side projects revolves around infrastructure: containerised services, Linux systems, CI/CD pipelines, and keeping things reliable at scale. I believe automation is always worth writing if you'll repeat a task more than twice.
Almost everything I build ends up open source — it's how I give back to the community that taught me most of what I know, and frankly it keeps me honest about code quality. If something I shipped is useful to you, that genuinely makes my day.

Own the Problem
From schematic to deployment — understanding the whole system leads to better solutions at every layer.
Build in the Open
Open source is how the community moves forward. Sharing work, receiving feedback, and learning together.
New Tech, Always
Curiosity is a skill. Staying close to emerging technology — embedded, infra, AI — keeps work interesting and solutions modern.
