Senior🎓
Top SchoolMilan Lesnek is a Senior Backend Engineer with nine years of experience designing and maintaining robust Python-based services, currently driving automation at Rossum after leading core-service refactors and Camunda workflow integrations at Kiwi.com. He blends hands-on engineering—owning services, increasing test coverage, and converting Celery workloads to workflow-driven orchestration—with practical QA sensibilities demonstrated by contributions to the widely used pytest project to harden warning handling. Based in Brno, he thrives on exploring new HW/SW projects and brings an engineer’s curiosity to production problems, paired with hobbies like 3D printing that often inspire creative problem-solving. Known for pragmatic refactors and reliable integrations (including a key Ryanair partnership implementation), he balances attention to detail with system-level thinking.
