During November 2025, contributed to the propeller-heads/tycho-indexer repository by developing a macro-based enhancement for the Price struct. This work focused on leveraging Rust’s macro system and struct design principles to streamline the struct’s interface, reducing boilerplate and improving usability across multiple modules. The approach enabled safer future refactors and promoted consistency throughout the codebase, aligning with project standards for maintainability. Although no bugs were addressed during this period, the feature delivered clear business value by accelerating future feature development and simplifying code paths. The work demonstrated a strong command of Rust, macro development, and thoughtful struct architecture.
