PROFILE
Aahan Aggarwal
Worked on the facebook/pyrefly repository over four months, focusing on backend and data processing improvements using Rust and JSON. Delivered four features and resolved three bugs, including a major refactor of the Glean module to adopt new fact constructors and naming conventions, which improved maintainability and onboarding. Enhanced schema safety and serialization efficiency by introducing safer value types and optional field handling, while also surfacing Python docstrings in Glean bindings. Addressed reliability by implementing hash-based JSON filename generation and fixing name resolution in GleanState, ensuring robust data integrity and cross-platform compatibility. Emphasized clean code, testing, and software quality assurance throughout.
