Open-source work
Open Source
My contributions to production-grade open source projects. Each entry represents a real investigation — finding, understanding, and fixing issues in codebases used by millions.
Contribution arc
Arrow's RapidJSON → simdjson migration
Migration foundation
Introduced simdjson and migrated Arrow's ObjectParser—the base for the wider C++ transition.
Core API & build rollout
Built JsonWriter primitives, enabled exception-free simdjson, and carried the migration through Arrow's build targets.
Subsystem migration wave
Extended the work across Parquet, Dataset, Flight SQL, integration code, extensions, tensors, and test utilities.
Final parser & chunker work
Driving the remaining JSON parser and chunker changes through review while reducing deserialization boilerplate.
One umbrella, many focused PRs: the work is shown as a single migration program—architecture, migration tooling, subsystem rollout, and review—not as a wall of individual pull requests.
