I have a strong background in optimizing and managing APIs, implementing testing frameworks, and improving project efficiency. I enhanced GraphQL API performance by adding data loaders, which reduced redundant calls by a factor of 10. Additionally, I implemented rate limiting in the API, effectively constraining endpoints to one request per second. My work in streamlining endpoint testing with Postman and Mocha, including developing and executing unit test cases, eliminated the need for manual testing, saving significant time. I also incorporated AWS CLI with Multi-Factor Authentication (MFA) to generate AWS CodeArtifact authorization, facilitating weekly back-end integration testing for the front end's shared component library. Furthermore, I facilitated over 200 SCRUM sessions, managed more than 300 KANBAN cards, and led five Agile retrospectives, ensuring project efficiency and continuous improvement. My contributions include designing over 40 pages of comprehensive technical documentation using Confluence, covering the GraphQL layer, front end, and integrations.
