- Manage and optimize testing environments using Docker Compose and CI/CD pipelines.
- Review code and test implementations to enforce best practices and maintainability.
- Test REST and GraphQL APIs for performance, reliability, and specification compliance.
- Document and maintain detailed test plans, test cases, and reports on results and coverage.
- Mentor junior QA engineers, providing guidance in automation, analysis, and debugging.
- Identify process improvements, propose test strategy enhancements, and drive automation efficiency.
- Collaborate with cross-functional teams to ensure timely delivery of high-quality software.
