1. Reduced bootup time of the core web application • Worked onreducing the bootup time for our core web application by migrating network calls to on-demand basis. • Optimised application performance by decoupling interdependent services through the implementation of service specific DAO layers. • Incorporated caching mechanism at Adapter layer. • This project reduced the bootup time from 3 minutes and 41 seconds to 2 minutes and 23 seconds. 2. Migrated core application to Serverless Architecture: • Designed the failure handling system for the event driven architecture and provided monitoring and alerting for risk mitigation. • This project reduced the overall cost incurred by the application by 74.5% 3. Took charge of improving Valuation web application’s codebase. Improved on code quality and test coverage resulting increase in the coverage by 35%. 4. Removed vulnerability from existing applications by upgrading Mybatis and Datelib versions.
