PROFILE
Mikaël Francoeur
Worked on the tursodatabase/turso repository to enhance database reliability, correctness, and automated testing. Focused on improving query processing and concurrency by addressing window function stability, refining error handling, and resolving MVCC Rowid race conditions to ensure unique row identifiers under concurrent transactions. Introduced Antithesis testing via CI configuration flags and expanded assertion macros, increasing test coverage and observability. Automated nightly and weekly test scheduling accelerated regression detection and release confidence. Aligned INSERT behavior for non-INTEGER primary keys with SQLite semantics, reducing maintenance complexity. Utilized Rust, SQL, and Docker, applying skills in CI/CD, debugging, and backend development throughout the work.

Feb 1, 2026February 2026 (tursodatabase/turso): Delivered targeted correctness, reliability, and CI improvements across core query processing and testing. Key work includes enabling Antithesis testing via CI cfg flag (replacing --features with --cfg antithesis), expanded assertion macros, and enhanced error reporting for easier debugging; substantive window function fixes addressing EXISTS subqueries, partition expressions, deduplicated partitions, and CTE references to prevent panics and incorrect results; MVCC Rowid concurrency fixes to eliminate duplicate rowids in concurrent transactions; and CI/build/infra enhancements for sanitizer coverage, container setup, and fuzzer/testing infrastructure. These changes reduce risk of incorrect query results, improve observability, and accelerate debugging in development and CI pipelines.
