Top SchoolKrzysztof Korolczuk is a Site Reliability Engineering Manager based in Warsaw with over a decade of hands-on software and engineering leadership experience, now building a modern reliability platform at Box.

Technically fluent across Java, Python, Go, Kubernetes and observability stacks (DataDog, Prometheus, ELK), he consistently drives reliability, performance and automation improvements in fintech and cloud-native environments. His background includes reducing integration pipeline times by an order of magnitude, introducing performance frameworks, and leading security audits and on-call redesigns. Colleagues know him as a pragmatic mentor who develops tech leads and builds repeatable programs like internship pipelines and competence libraries. He combines deep operational discipline with a knack for turning organizational challenges—onboarding, on-call, observability—into scalable engineering practices.
