Working as part of the Access team to enhance a high-performance API that provided user management, routing, and authentication services for Marketplace and Medicare related applications, supporting millions of requests annually. I later transitioned to the Data team, where I contributed to the development and maintenance of the Healthcare.gov Data API, ensuring reliable and efficient service for millions of healthcare-related requests. In collaboration with clients and stakeholders, I provided technical assistance and ensured smooth integration of services. My work involved using a range of tools and technologies, including AWS (S3, EC2, ECS, CloudWatch), Splunk, New Relic, Docker, Confluence, Jira, and Terraform, to build scalable and efficient solutions. I primarily used the Go programming language and PostgreSQL database to support the delivery of secure, high-quality back-end services.
