During May 2025, contributed to the rosetta-models/common-domain-model repository by enhancing the Valuation type with a new scope attribute and introducing the ValuationScopeEnum, supporting both Collateral and Trade contexts. This domain modeling work in Rosetta enabled more granular valuation data, laying the groundwork for improved reporting and analytics across products. The implementation focused on backward-compatible schema evolution and careful enum design, ensuring existing integrations remained stable while extending functionality. Throughout the process, maintained strong Git hygiene and clear documentation, resulting in a robust foundation for scope-based reporting and decision-making within the valuation domain, without introducing any new bugs.
