What I'm looking for

I’m looking to deliver reliable, production-safe releases in Agile teams—owning regression and UAT, building Selenium/Cypress/Karate automation, and partnering with developers to strengthen CI/CD quality gates while improving automation maturity.

I’m a Quality Engineering professional specialising in enterprise-scale software testing, automation engineering, and quality strategy. I deliver reliable releases by improving automation maturity and reducing production risk across complex platforms.

Over 10+ years, I’ve built and maintained automation frameworks for UI and API validation, and strengthened automated regression coverage. I’m experienced in Agile delivery, CI/CD quality gates, and DevOps integration—working closely with developers to reduce production defects.

My work spans UI, API, database, integration, regression, and UAT testing, with a focus on quality evidence, defect reporting, and stakeholder engagement. I’ve validated microservices and supported data migration validation to ensure data integrity.

I’m especially strong in test automation using Selenium, Cypress, and Karate, leveraging tools and platforms such as Jenkins, Azure DevOps, and TestRail. I’m motivated to keep raising the bar on automation effectiveness—advising teams and clients on QA strategy and process improvement.
