Utkarsh Pandey modernized the juspay/connector-service backend by introducing a modular architecture, decoupling dependencies, and restructuring the codebase for maintainability. He implemented a cross-provider CurrencyUnit abstraction and an integrity framework to ensure robust data consistency across payment flows. In addition, Utkarsh developed a Source Verification Framework, standardizing response validation and enhancing security for multiple payment connectors. His work leveraged Rust and Python, focusing on API design, error handling, and system architecture. Over two months, Utkarsh delivered four features that improved backend flexibility, security, and data integrity, demonstrating depth in backend development and thoughtful application of modular design principles.

July 2025 monthly summary for juspay/connector-service.
