Senior QA Engineer with 5+ years of experience delivering reliable, scalable software by embedding quality across the entire development lifecycle. I work with fast-growing startups and enterprise teams in agile environments, combining strong manual testing, modern test automation, and DevOps-aware practices to ensure end-to-end quality, faster releases, and higher confidence in production.
I specialize in building and maintaining scalable automation frameworks that reduce regression risk and support continuous delivery. My approach focuses on shift-left testing, realistic test coverage, and collaboration rather than isolated test execution.
Key strengths and experience include:
• End-to-end quality engineering across web, API, data-driven, and AI-powered systems
• Test automation using Playwright, Cypress, Selenium, and MABL with strong cross-browser coverage
• API testing and automation using Postman and RestAssured (Java), including integration and performance testing with JMeter
• Experience testing AI/ML applications, including MCP (Model Context Protocol) integrations for LLM-driven automation workflows
• DevOps-aware QA with hands-on experience in Docker, Kubernetes, Git, Jenkins, and CI/CD pipelines
• Backend and data validation using SQL to ensure data integrity and reliable system behavior
In addition to automation, I bring strong manual testing expertise and a proactive quality mindset.
Additional capabilities include:
• Exploratory, usability, accessibility, regression, smoke, and acceptance testing
• Close collaboration with developers, product managers, and designers to ensure true end-to-end quality
• Participation in code and design reviews to improve testability and prevent defects early
• Test data creation, environment management, and validation of complex test scenarios
• Defect tracking and test management using Jira, TestRail, and Confluence
Beyond testing, I have built workflow and process automation using platforms such as n8n, Zapier, Make, HubSpot, and custom API integrations, delivering solutions that reduced manual effort and improved operational efficiency.
I bring strong ownership, leadership, and communication skills, manage multiple test initiatives effectively, and adapt quickly to new tools and technologies. My focus is always on practical, maintainable quality engineering that supports real business outcomes.
