Senior🎓
Top SchoolXenia Foxtrot is an SDE2 with 11 years of engineering experience who builds full‑stack web systems using C#, PHP, React, TypeScript and Rust, currently contributing to Amazon’s Kuiper Commerce team from Redmond. They have a proven track record shipping developer productivity and identity features at Microsoft and Dropbox, including an internal deployment tool that materially sped up release cycles and a GitHub-based sign‑in flow. Xenia pairs production engineering with low‑level language work—having contributed to OCaml’s core by implementing the tast_iterator for typed AST traversal—which highlights comfort across both systems and application layers. Colleagues rely on them for thoughtful cross-team collaboration and customer‑facing engineering support that turns feedback into product improvements. Beyond code, they bring a mathematical curiosity and a habit of shipping pragmatic open‑source patches that make dense systems easier to maintain.

Contributions summary:Xenia primarily contributed to the OCaml core system by implementing and updating the `tast_iterator` module, which is crucial for typed tree inspection. Their work involved defining iterator types and implementing the core functionality of `tast_iterator.ml` which enables open recursion. These contributions included modifying the structure and implementation details of the iterator, as well as fixing compilation errors.
