About
The story
I got curious about how systems work, and never really stopped. That curiosity carried me from antivirus QA benches and university lab servers to co-owning a data-centre - and from Perl scripts to SvelteKit products.
Great software lives where technical excellence meets real user needs. The systems I build are designed for three things: reliability, scalability, and the ability to be maintained by whoever comes next - usually me, at 3 a.m.
Today I split my time between running production infrastructure and shipping the products on top of it. The rest goes to open source - WHOIS clients, DDoS tooling, and whatever itch needs scratching.
Prefer the unabridged version? Every role, stack, and degree since 2005 is on my full CV.

Philosophy
Three principles that have survived two decades of production.
Uptime is a feature. I design for failure, monitor everything, and page myself before the customer ever notices.
Start simple, design for growth. Microservices, containers, and cloud-native patterns - where they earn their keep.
If it happens twice, it gets automated. Config management, CI/CD, infrastructure as code - human time is for human problems.
I'm currently open to new opportunities. Let's build something great together.
