Rockstar🎓
Top SchoolMichał Kordas is a Lead Java Developer and Software Quality Engineer with 12 years of experience driving high-quality, production-grade Java and JVM-based systems from Krakow. He blends deep developer skills with obsessive attention to quality—practicing TDD, BDD, ATDD and evolutionary design—to bring micro-level feedback loops and continuous delivery to Agile teams. At Luxoft he operates as a cross-functional technical automation tester, analyst and backend developer, working with Spring, Groovy, Maven/Gradle, TeamCity/Jenkins and a broad testing toolset (JUnit/TestNG/Spock, Mockito, JBehave) while enforcing static analysis via Checkstyle/PMD/FindBugs/SonarQube. His open-source contributions include quality and test improvements to widely used projects like Checkstyle and AssertJ, reflecting a practical focus on readability, correctness and better assertions. Comfortable in both Agile and mission-critical system contexts, he also delivers trainings on Java and agile testing and frequently converts complex requirements into concise, automatable test suites. Not obvious at first glance: he actively reduces technical debt through small, targeted refactors (e.g., StringBuffer→StringBuilder, @Override and JavaDoc fixes) that improve maintainability across codebases.
