Summary
🤩
Rockstar🎓
Top SchoolThomas Mueller is a Senior Developer based in Basel, Switzerland with 19 years of experience building robust back-end systems and database engines. He has spent over a decade at Adobe and earlier roles at Day, Swisscom, PointBase and Miracle, bringing deep experience in Java, JDBC, storage engines and query/index optimization. An active open-source contributor, Thomas has made notable contributions to Apache Jackrabbit and Jackrabbit Oak—implementing a database-backed data store and improving indexing and query behavior—and to H2 where he fixed MVStore transaction and BLOB/CLOB issues. His work blends hands-on bug fixing and performance tuning with thoughtful schema and storage design, making him as comfortable in low-level data integrity problems as in large-scale system improvements. Colleagues would recognize him for quietly solving gnarly database edge cases and improving long-term stability in critical storage code.
