QA Engineer Jan 2021 - Jan 2023
YSBM Group
Served as the sole QA Engineer for a core web project, owning manual testing, regression coverage, defect reporting and automation
recovery while supporting ongoing feature delivery.
• Owned QA activities across the project, covering manual functional testing, regression testing, defect reporting and release validation.
• Took over an automation suite that had been unreliable for around two years and gradually restored it by fixing failing code, updating
selectors and stabilising test execution.
• Maintained and extended Laravel Dusk automation while continuing to test new functionality and support delivery priorities.
• Implemented automated coverage for new features, ensuring regression checks kept pace with ongoing development.
• Analysed test failures, identified root causes and worked with developers to resolve defects and improve stability.
• Created clear bug reports with reproduction steps, evidence, expected and actual behaviour and impact notes.
• Suggested migration from Laravel Dusk to a more modern automation framework, contributing to the later transition toward Cypress.
• Used Trello for test case management and task tracking.
Key Contributions
• Recovered and stabilised a legacy automation suite that had been broken for two years, increasing the test pass rate from 2% to 90% and
turning it into a reliable tool for regular regression checks.
• Balanced sole-QA ownership with automation maintenance and new feature testing in a fast-moving project.
• Helped modernise the project's automation approach by recommending a move away from Laravel Dusk.
