Summary
🤩
Rockstar🎓
Top SchoolMarcin Matłaszek is an SRE consultant based in the Cracow metropolitan area with 14 years of hands-on experience building and operating resilient infrastructure. He has progressed from Linux systems administration and team leadership to DevOps and SRE roles at companies including Base CRM (acquired by Zendesk) and Chainlink Labs, focusing on reliability, process management, and operational tooling. Marcin contributes to notable open-source projects such as HashiCorp Nomad, where he implemented process group handling and Windows compatibility improvements to make process cleanup and logging more robust. He combines deep Unix internals knowledge with pragmatic automation practices, often tackling edge cases that break at scale, like I/O resilience and cross-platform process semantics. Educated to an M.Sc. in Computer Science from the Tadeusz Kościuszko Cracow University of Technology, he brings both formal foundations and long-term production experience to platform stability and developer ergonomics. Colleagues describe him as a steady engineer who prefers durable, low-surprise solutions over flashy but brittle optimizations.
