• Devised and implemented a custom exception handling solution for our lambda-based async service, maintaining lambda instances despite increased runtime exceptions.
• Migrated in-station and on-road events from legacy to new service, establishing a unified notification authority. Developed a shadow-testing framework with AWS resources (Kinesis Stream, Athena) for event comparison via SQL queries.
• Executed load testing for both synchronous and asynchronous tier-1 services, simulating production traffic in the Gamma environment. Achieved a 5% reduction in the host fleet as a result.
• Integrated A/B testing into an asynchronous Lambda-based service with AWS Evidently, enhancing testing efficiency and enabling comprehensive analysis. The outcome contributed to an optimized user experience.
• Implemented a regression test suite for a tier-1 asynchronous service, enhancing deployment validation in the pre-production environment. Resulting in 90% decrease in downstream tickets.
• Demonstrated operational excellence by resolving critical tickets on package replanning and notification generation. Developed scripts to re-trigger events, update DynamoDB entries, and modify S3 files, showcasing proactive problem-solving skills.

• Assisted the LifeCycleManagment team inside Core Transport Technology org:
• Led the design and developed a custom analytics tool using various AWS resources like kinesis-firehose, S3, Athena for an async tier-1 service that is responsible to generate notification for customers based on any given event from upstream. This tool provided visibility into lifecycle of a package, as well as reducing debugging time by 90 percent for the service.
• Designed implemented a solution for onboarding a new upstream to monitor Revised EDD program events. Developed a Lambda handler via CDK on the async gateway service, enabling efficient communication of revised estimated delivery dates to customers, significantly enhancing overall customer experience.
• Engineered a JavaScript script facilitating message pushing to SQS, enabling robust load-testing of freshly developed Lambda handlers, ensuring their scalability and performance optimization.
• Enhanced team runbooks, elevating service coverage from 82 to 100 percent for unit tests (line and branch).
