Worked on tursodatabase/turso and com-lihaoyi/mill, delivering features and fixes that improved database reliability, cross-platform compatibility, and deployment workflows. Enhanced Turso’s transaction handling, materialized view integrity, and JSON query capabilities using Rust and SQL, addressing issues like row loss, CTE propagation, and numeric filtering. Improved Android support by introducing a pure-Rust library, eliminating C cross-compilation. Expanded incremental view maintenance and added experimental materialized views support to Rust bindings. For Mill, implemented Jib-based Docker image building in Scala, reducing Docker daemon dependency and streamlining image creation. Emphasized robust testing, schema design, and asynchronous programming throughout the development process.
February 2026: Focused on improving deployment efficiency and MV reliability while expanding cross-language MV experimentation. Implemented Jib-based Docker image building as default for Mill's contrib/docker backend, enabling daemonless builds while preserving the ability to build with a Dockerfile via ClassicDockerConfig; introduced core Jib integration files to support the new workflow. Strengthened Turso materialized views with new tests and reproducers for DBSP state index integrity, INSERT OR REPLACE panic with dependent MV, and CREATE MV in the same transaction. Added experimental materialized views support to Rust bindings and test runner to broaden experimentation and adoption. Overall, reduced Docker dependency, increased MV safety, and expanded cross-language MV capabilities.

December 2025 focused on strengthening data reliability and SQL feature completeness in tursodatabase/turso. Key efforts delivered robust JSON construction (json_object/jsonb_object) with safe string escaping, improved materialized views stability, reliable CTE handling in compound queries, and correct numeric filtering across Integer/Float types. These changes deliver tangible business value: safer data interchange and query generation, more dependable analytics through stable materialized views, and correctness in complex query scenarios, reducing debugging time and risk of data loss. Technologies demonstrated include advanced JSON handling, function star expansion, cursor/resume logic, CTE scope management, and numeric type consistency, all backed by added tests.
