Worked on the OWASP/Nest repository to deliver three key features focused on API security, reliability, and performance. Migrated the REST API fuzz testing framework to Schemathesis, introducing automated REST fuzz tests and middleware for handling null characters to enhance robustness. Improved CI/CD workflows and refined Docker configurations and environment variables to streamline deployment and testing processes. Enhanced database management commands and optimized API query parameters for safer, faster operations. Refactored GraphQL strawberry_django decorators to improve User data retrieval efficiency, resulting in better related-field fetching. Utilized Python and YAML extensively, applying skills in backend development, API testing, and deployment automation.
