About

Who I am

Software engineer with 15+ years in the .NET ecosystem, specializing in distributed systems, event-driven architecture, and building high-performing engineering teams.

I care deeply about delivery predictability, code quality, and empowering engineers to do their best work. I believe great software is built by great teams, and great teams are built on trust, clarity, and continuous improvement.

Open source maintainer and Debian packager. When I'm not architecting distributed systems, I'm contributing to the open source community or writing about engineering on my blog.
