In February 2026, Pawan implemented upsert functionality for portfolio trading accounts within the Backbase/stream-services repository, enabling both creation and update operations for investment portfolios. He enhanced the service layer to improve trading account data handling and introduced robust error handling to ensure data integrity and reliability. Working primarily with Java and the Spring Framework, Pawan also addressed asset patch requests by enabling new value assignments and resolving related unit test failures. His work focused on backend development and RESTful API design, resulting in faster onboarding for portfolio management and improved maintainability, though the scope was limited to a single feature.
