Worked on the CAUCSE/CAUSW_backend repository, focusing on backend development and data quality improvements using Java, SQL, and Spring Boot. Delivered features that enhanced user onboarding by refining phone number validation and standardizing formats, ensuring consistent data representation and reducing downstream errors. Addressed privacy concerns by remediating anonymous post handling, updating serialization logic to prevent exposure of writer details in API responses. Improved search accuracy by fixing data retrieval for user admission attachments and streamlined code maintainability through targeted refactoring. The work emphasized robust DTO design, validation, and database management, resulting in a more reliable and secure backend system.
