2016 - 2017Expedia Group- Wrote a RESTful Java web service for the Task Execution Framework (TEF) and set up service dashboards, monitoring, and alerts using Splunk telemetry data.
- Set integration tests for an asynchronous processing framework to test end-to-end calls across multiple microservices and a Jenkins build job to automate running these tests in the build pipeline.
- Built the next generation of payment processing services that process 97% of Expedia's transactions, leading to a 25% reduction in annual hardware costs.

2015 - 2016Microsoft- Wrote an OData-based RESTful WCF data service for the team's component testing framework. The service implemented create-read-update-delete (CRUD) operations for three graph-client-helper library requests and could support additional ones.
- Optimized the end-to-end (E2E) tests' code flow for account provisioning flows, reducing their execution time from 60–80 to 40–45 minutes. Defined runner phases as part of quality improvements to help ascertain what code module caused a test failure.
- Cooperated with other senior developers to decrease the system test failure rate by 90% while reducing the test execution time by 50%. It also helped save hardware costs by more than 10%.
