Software Engineering
I’ve been writing software since 2008, across startups and large-scale platforms. I led Platform Engineering at AutoScout24 and Trader — evolving legacy systems, scaling infrastructure, keeping developer experience sharp — and now run Engineering Effectiveness for the same 800+ engineers, which means I also get to see what every one of those decisions costs.
These posts cover the craft of building software that lasts—testing strategies, tackling technical debt, platform engineering patterns, and the architectural decisions that matter at scale. Practical advice grounded in real-world experience.
