During October 2025, Mahdi Baghbani enhanced the cs3org/reva repository by addressing a critical bug in OCM address parsing. He developed a robust solution in Go that accurately handles addresses containing multiple '@' symbols, ensuring correct extraction of user IDs and providers. By introducing validation to reject empty fields, Mahdi improved the reliability of cross-provider identity resolution and reduced the risk of misrouting. His work involved backend and API development, with a focus on string manipulation to strengthen parsing logic. Comprehensive test coverage was added to verify error scenarios, reflecting a thoughtful and thorough approach to backend engineering challenges.
