Built and owned the test automation infrastructure for an AI product company, from framework design to IoT hardware validation. My mandate wasn't just QA; it was making quality a first-class engineering concern across a fast-moving team. Designed a Playwright-based automation framework from scratch,increased regression test coverage by 40% and cut manual testing effort by 15 hours per week, freeing the dev team to ship faster without blind spots. Pioneered AI-assisted test automation using Playwright Test Agents (Planner, Generator, Healer modules) to auto-generate and self-heal test scenarios reduced script maintenance overhead by 25% even as the product evolved rapidly. Led E2E and IoT testing for Wiliot hardware systems: validated real-time telemetry data flows over MQTT using device simulations, achieving 99.9% data accuracy a standard typically required in production-grade hardware deployments. Championed a shift-left testing culture, embedding QA checkpoints into sprint planning and CI pipeline gates to catch issues at the source rather than post-merge.

Served as the core automation engineer for a Node.js/React ERP product responsible for API test coverage, release quality, and CI/CD integration across a two-year product lifecycle. Architected an API automation framework in Cypress for RESTful services, directly reducing API-related production defects by 30% and giving the team confidence to release more frequently. Executed comprehensive E2E test scenarios across the full ERP stack (Node.js backend, React frontend) — identified and documented 150+ high-severity bugs before release, preventing significant post-launch incidents. Integrated automated test suites into the CI/CD pipeline (Jenkins/GitLab), enabling continuous regression feedback within pull request workflows and cutting feedback cycle time substantially. Validated complex MySQL database schemas with structured SQL validation scripts, ensuring data integrity across web and mobile platforms under real transaction loads.

First dedicated QA role in a product company, built automation coverage from near-zero, introduced structured bug workflows, and validated data integrity across a multi-platform product. Automated 200+ test cases in Cypress across web and API layers, reaching 85% automation coverage for core business modules, a foundational coverage milestone for the product. Implemented structured Jira bug workflows to formalise the defect lifecycle, accelerating the defect-fix cycle by 15% and improving cross-team visibility into release readiness. Designed and executed SQL validation scripts against MySQL schemas to ensure cross-platform data integrity, caught schema-level discrepancies that functional tests would have missed entirely.

About

Quality engineering, for me, has always been more than finding bugs. It’s about building systems that help teams ship confidently and move faster without breaking things. Over the last 4+ years as an SDET / QA Automation Engineer, I’ve worked on building and scaling automation frameworks using Playwright and Cypress, integrating them into CI/CD pipelines, improving regression coverage, and reducing flaky execution across fast-moving products. At DotAi Corp, I worked on AI-assisted test automation using Playwright’s Planner, Generator, and Healer modules to reduce maintenance overhead while supporting rapid product changes. I also handled IoT validation for Wiliot hardware, testing real-time telemetry over MQTT with high data accuracy. Previously at CRESC Datasoft, I built Cypress API automation frameworks for REST services, helped reduce API-related production defects, and worked extensively on database validation, CI/CD integration, and end-to-end quality workflows. What I enjoy most is building automation that stays maintainable as products scale — fast feedback pipelines, meaningful coverage, and frameworks teams can actually rely on long term. 📍 Bengaluru, India · Open to remote opportunities
