Rockstar🎓
Top SchoolMaciej Brencz is a Senior Software Engineer with 18 years of experience building and operating large-scale, data-intensive systems that handle terabytes of data and thousands of requests per minute. He specializes in observability—metrics, logging, monitoring and alerting—to keep complex platforms simple, stable and easy to debug, and has driven measurable improvements like dramatic search index and query-time reductions. At Automattic he built a large-scale WordPress backup solution and its CI pipeline, and earlier roles at FANDOM involved end-to-end analytics pipelines on AWS and Kubernetes migrations. He contributes to open source—improving SQL metadata parsing and PHP code clarity in widely used projects such as SemanticMediaWiki—and enjoys digging into why software breaks as much as how it works. A collaborative mentor with a multicultural background, his Gallup strengths (Learner, Ideation, Deliberative, Developer, Empathy) reflect a pragmatic curiosity and people-first approach to engineering. Based in Greater Poland, he blends deep backend and data engineering skills with a knack for making systems both efficient and maintainable.
