What I'm looking for

I’m looking for an Agile QA role where I can own manual + API validation, improve data accuracy, and strengthen defect prevention (including WCAG/accessibility and regression). I want a team that values CI/CD-aligned testing and fast, collaborative delivery.

I’m an ISTQB-aligned QA Engineer with 3+ years of experience specializing in manual testing, API validation, and Agile QA delivery across high-traffic web and dashboard applications. I focus on rigorous data-payload validation and structured defect tracking to improve quality before release.

In my role at IOT83, I spearheaded API testing using Postman and Swagger, improving API reliability by 35% through rigorous data-payload validation. I also validated dashboard data flows and third-party integrations, resulting in a 45% uplift in operational reporting reliability for enterprise clients.

At Team Oreo, I combined QA with frontend understanding to execute functional, accessibility, and cross-browser testing for a WCAG 2.1-compliant application, ensuring 100% compliance across 5+ platform configurations. I identified and tracked critical UI defects through structured testing pipelines, reducing post-release user complaints and accelerating defect resolution times by 20% through close Agile sprint collaboration.

I bring end-to-end ownership of the defect lifecycle using Jira and repeatable regression approaches (Integration, Regression, and E2E). Whether diagnosing bottlenecks to reduce load times by 30% or supporting CI/CD alignment for zero-defect deployments, my goal is clear: reduce post-release production defects and help teams ship faster with confidence.
