01 — About

A bit about me.

I'm a software developer with a strong focus on backend engineering, frontend craftsmanship, and connected devices. I enjoy working at the seams of systems — designing APIs, modeling domains, and turning business rules into code that's easy to read, test, and evolve.

Over the years I've built and maintained production systems in Ruby and Ruby on Rails, shipped services and tooling in C# / .NET, leaned on Golang for performance-sensitive microservices, and crafted interactive interfaces with Vue.js and Svelte.

I also work on IoT systems — bridging embedded devices, edge gateways, and cloud services into reliable, observable pipelines.

Outside of writing code, I care about developer experience: clean logs, sensible defaults, documentation that doesn't go stale, and tools that get out of the way.
