• Test Automation: Built and maintained frontend automation frameworks using Selenium and Robot Framework (Python), ensuring robust test coverage for web applications. Automated mobile apps for Android and iOS using Appium.
• Performance Engineering: Conducted end-to-end load testing, creating comprehensive scenarios to simulate system-wide load, integrating scripts from all related products. Adopted a shift-left approach by incorporating load testing tools (JMeter, Gatling, k6, CloudTest) into CI/CD pipelines for early performance insights. Monitored web page performance metrics (LCP, FID, CLS) using Sitespeed in CI/CD to ensure a seamless user experience.
• AI Tools & Prompt Engineering: Leveraged AI tools like Microsoft Copilot and GitHub Copilot for prompt engineering to generate, review, and optimize code, enhancing development efficiency and code quality.
• Resilience and Chaos Testing: Validated system reliability through Gremlin-based resilience testing, and implemented chaos engineering practices.
• Cloud Management: Managed cloud infrastructure with IaC, writing Terraform scripts and provisioning AWS resources (IAM, ECS, EC2, S3, ElastiCache, Redis, SES) to support QA activities.
• CI/CD Integration: Developed and optimized automated testing pipelines with Jenkins and GitLab, including multi-project pipelines, job scheduling, and automation.
• Development & Tooling: Enhanced developer productivity by creating an internal portal (Cortex) as a one-stop shop for engineers, integrating tools like New Relic, VictorOps, AWS resources, IaC pipelines, and GitLab repos. Implemented scorecards to monitor quality, resilience, security, and architecture thresholds, blocking pipelines when criteria were unmet.
• Monitoring & Metrics: Analyzed performance metrics during testing (e.g., response times, error rates, LCP) and implemented optimizations to improve system reliability.
• Leadership and Collaboration: Led QA initiatives, mentored teams, and drove process improvements to align with organizational quality standards and objectives.

Continuous Testing: Integrated continuous testing with API development, enabling early and frequent testing across dev and QA environments. Automated API tests run every hour in production, covering various end-user flows, and providing results within a minute to ensure environment stability.

Performance Testing: Created load testing scripts simulating real-world scenarios, distributing track across application parts. Implemented InfluxDB and Grafana with JMeter for real-time load monitoring. Analyzed New Relic data during load tests, checking service behavior and server resource utilization, reported areas for improvement, highlighting bottlenecks, and risks.

UI Automation: Developed a data-driven UI automation framework using Java, Selenium, and Appium. Deployed test scripts on Jenkins for continuous integration. Enhanced the framework for better coverage, and executed parallel tests for Android, iOS, and web applications.
