Sailaja worked on the juspay/decision-engine repository, delivering targeted backend improvements to payment gateway selection and emandate processing. She enhanced gateway filtering by addressing case sensitivity in gateway matching and introduced detailed logging to improve observability and streamline debugging. Using Rust, she corrected the MGA retrieval logic for emandate flows, ensuring the correct function was called based on merchant and reference IDs, and optimized performance by adding an early return path for specific transaction types. Her work demonstrated strong backend development and debugging skills, resulting in more reliable payment processing and reduced troubleshooting time for the team’s Rust-based systems.
