Project Experience

Microservices API Regression Suite

Built comprehensive API regression suite for a microservices-based platform, automating 200+ API endpoints and reducing manual testing effort by 70%. Technologies: RestAssured, Java, TestNG, Jenkins.

Contract Testing Implementation

Designed and implemented contract testing for API integrations, ensuring compatibility between services and preventing breaking changes. Technologies: Pact, Postman, CI/CD, Git.

API Performance Testing

Developed automated API performance tests, identifying bottlenecks and optimizing response times for high-traffic endpoints. Technologies: Newman, JMeter, GitHub Actions, Monitoring Tools.

LLM API Contract Testing

Built automated test suite to validate a GPT-4-powered summarization API endpoint, covering response schema validation, hallucination rate checks, consistency under repeated prompts, and timeout/retry behavior. Integrated with CI pipeline for nightly validation. Technologies: RestAssured, Java, GitHub Copilot, LLM API Testing, GitHub Actions, Pact.

Work Experience

SDET - API Testing
