• Working with First and Last Mile team to enhance the pickup and delivery operations globally.
• Implemented a REST API from scratch which provides more accurate itinerary planning for first and last mile operations affecting millions of packages daily.
• Implemented multithreading using CompletableFuture and ExecutorService, resulting in a 63% reduction in response time.
• Improved unit test code coverage from 30% to 90%, significantly increasing the reliability and maintainability of the application while reducing potential defects.
• Developed a start-stop Jenkins pipeline to restart applications on specific servers instead of full redeployment, reducing recovery time from 4m 30s to under a minute and ensuring rapid resolution of unexpected downtimes.
• Enhanced application robustness by implementing user input validation and global exception handling.
• Created comprehensive API documentation using Swagger with OKTA authentication.
