PROFILE

Vladimir Rangelov

Over a three-month period, contributed to the rdkcentral/firebolt-apis and firebolt-openrpc repositories by delivering features and stability improvements focused on API efficiency, CI/CD reliability, and test coverage. Implemented API request cleanup in JavaScript to omit null optional parameters, refactored the transport layer, and added unit tests to improve payload efficiency and maintainability. Enhanced CI/CD pipelines using GitHub Actions and CodeQL, resolving workflow permission issues and integrating static code analysis for better security. Expanded component test coverage in C++ with CMake, refactoring test infrastructure to ensure consistent execution in CI, thereby reducing regression risk and accelerating feedback for API evolution.
