Rockstar🎓
Top SchoolTomasz Łasica is a Senior Software Engineer based in Warsaw with 14 years of experience building and testing distributed systems, NoSQL platforms, and performance-critical services. He combines deep hands-on skills in C++, Scala, Java and Python with practical leadership in Agile practices—having moved between roles as developer, scrum master, and engineering manager. At DataStax he stabilized large-scale test suites, created automated performance testing fleets, and took ownership of the widely used butler test-aggregation tool. More recently he contributed to Snowflake and now Starburst, bringing expertise in Cassandra, Solr, Spark and production issue triage. Tomasz is especially strong at bridging peopleware and engineering: he embeds testers into developer workflows to raise quality and uses measurable tests to de-risk releases. His career shows a recurring pattern of rescuing brittle systems and turning testing and processes into repeatable, engineering-first assets.
