Top SchoolSerhii Borysenko is a data-focused QA and Big Data engineer with six years of experience testing and validating complex cloud-native, microservices architectures. He combines hands-on API, WebSocket and database-level testing (CockroachDB, Cassandra) with automation using Python, Playwright and Selenium to cut regression times and improve API testing efficiency. Serhii has deployed stress tests, analyzed P99 latency and OpenTelemetry traces in Grafana to verify performance fixes, showing an unusual depth in observability-driven quality assurance. Comfortable in multinational Agile teams, he bridges development and QA by collaborating daily with engineers and maintaining test artifacts in TestRail, Jira and CI/CD pipelines. With a master’s in Materials Science and a transition toward big data tooling, he brings analytical rigor and systems thinking that help uncover issues not obvious from UI-level tests. Based in Kyiv, he pairs pragmatic automation skills with low-level data validation to ensure robust, production-ready services.
