Worked on expanding credit score compatibility in the mxenabled/path-mdx-model repository by implementing Vantage Score support within CreditReport ScoreVersions. Used Java and enum-based version management to add VANTAGE_SCORE as a valid score version and upgraded to VANTAGE_SCORE_3, enabling accurate recognition and processing of Vantage Score credit reports. The approach focused on maintainable code changes and disciplined data modeling, executed through two targeted commits that improved score-version handling. This work reduced processing errors and improved scoring accuracy, supporting better risk decisions and future enhancements. Demonstrated skills in Java development, data modeling, and versioning within a production codebase.
