I'm a software engineer and DevOps engineer based in Kraków, Poland who loves turning complex infrastructure ideas into clean, production-grade systems. After 5 years shipping enterprise SaaS features at HCL Software, I moved into a DevOps role at Pegasystems and continue to build TheyCloud — a production-grade white-label cloud platform I designed and built from scratch.
TheyCloud at a glance: 250K+ LOC · 124+ REST APIs · 354 domain events across 24 business contexts · 50+ DB tables · 44+ test suites (80%+ coverage)
- 🏗️ Side project → TheyCloud — white-label cloud platform (node-licensed)
- 💼 Currently → DevOps Engineer at Pegasystems, Kraków
- 🌱 Always learning → distributed systems, event-driven design, Go performance
- 🇵🇱 Relocated from Istanbul → Warsaw → Kraków
A fully custom cloud management platform covering the entire stack:
