Created a new algorithm to perform accurate syntactic search with partial code fragments, implemented a tool prototype using TreeSitter in Rust to search over JavaScript files.

Designed a new IDE user experience to support interactive syntactic code search queries, implemented an internal Python prototype, and then integrated it into the Swift codebase.

Designed and implemented a tool in OCaml to type-check rewrite patterns for a C++ subset

Adapted the GumTree syntax-aware diffing algorithm to Python to extend FLOR to allow developers to compare metrics across historical versions of model training pipelines.
