Ecosystem Enhancement: Contributed to improvements across the OCaml ecosystem, including the OCaml compiler, concurrency libraries (domainslib, Eio), platform tools, and community initiatives.
Parallel Programming: Co-developed and maintained domainslib, a task parallelism library for OCaml, implementing optimized parallel algorithms for array operations and parallel scan functionality.
Effects based IO: Contributed to the Eio library (algebraic effects-based direct-style I/O for OCaml) by designing and implementing benchmarking infrastructure with performance metrics, while serving as release manager for Eio 1.0 to ensure a smooth, well-coordinated deployment.
Lockfree Data Structures: Bootstrapped the Saturn library of concurrent data structures for OCaml 5, mentoring new contributors and conducting code reviews for complex implementations including lock-free hashmaps and skiplists.
Team Leadership: Founded and led the ‘Multicore Applications’ team from inception to 10 members, managing key client relationships with Jane Street and Nomadic Labs while supporting the Engineering Manager with project management responsibilities.
