About Mateusz

I help engineering teams ship faster and more reliably by standardizing and automating the software delivery lifecycle. CI/CD design, self-service pipelines, release automation, infrastructure as code, Kubernetes, and cloud automation across AWS, Azure, and GCP.


Recent outcomes: at Nike I consolidated five teams' manual server-upgrade process for 900+ retail stores into one self-service pipeline, cutting per-server runtime from 6-8 hours to about 3 and reclaiming 600+ engineering hours a year. At ASML I built self-service CI from scratch in a tightly access-controlled environment, freeing another 300+ engineering hours a year.


How I work: simplify the delivery process, standardize it with guardrails, automate with pipelines, then hand it over so the team runs it without me. Defined-outcome engagements, not staff augmentation.


Based in the Netherlands, working with EU and US clients. B2B through my own company (Expeditious Software). Available for remote contract work.
