About Me

Technical Architect & DevSecOps consultant based in London. Building what ships. Automating what doesn't.

About Lukasz Raczylo

I wrote my first program at 6 and ran my first public Linux server at 12. What started with BASIC on a hand-me-down computer became a 25-year obsession with making systems work.

I've architected platforms for UK Government departments where downtime isn't an option and security clearance is table stakes, led DevOps and SRE teams across ministries, and delivered over £75M in cost savings by replacing expensive vendors with elegant, open-source solutions that actually work better.

I've shipped 20+ open source projects because I believe the best tools should be available to everyone—Kubernetes operators, security plugins, developer utilities, and more. I still run a 24-node Raspberry Pi cluster at home that hosts production workloads, including this very website. Partly because I love tinkering, partly to prove that good infrastructure doesn't need a massive budget.

I bring that same mindset to every engagement: pragmatic, cost-conscious, and obsessively focused on solutions that ship, scale, and let everyone sleep through the night. The best infrastructure is the kind nobody notices.
