Worked on the OpenGamma/Strata repository to deliver an FX Options Strike Price Inference feature, addressing the challenge of missing strike prices in FX option input data. Developed robust Java back end logic that automatically infers the strike price during parsing, reducing data gaps and supporting more reliable downstream valuations. Focused on enhancing data completeness and parsing robustness, the implementation included comprehensive unit testing to ensure code quality and maintainability. This targeted feature improved data quality for users, minimized manual data-cleaning efforts, and enabled more accurate risk calculations, reflecting a methodical approach to back end development and collaborative engineering practices.
