Senior QA Tester | Manual, API & Web Application Testing

I help businesses test web applications, APIs, integrations, and business workflows before issues reach their customers. I'm a Senior Software QA Analyst with 12+ years of experience in software testing, primarily working with web-based applications in Agile environments. My strongest areas are manual/functional testing, regression testing, API testing, integration testing, UAT, and end-to-end business-flow validation. What I can do for your project 🔹 Manual & Functional Testing Functional testing Regression testing Smoke & sanity testing UAT End-to-end testing Positive, negative, boundary & edge-case testing Test scenario and test case creation Requirements review and test analysis 🔹 API & Integration Testing REST API testing Request/response validation Status code and error handling JSON/XML validation API-to-UI validation Integration testing Data-flow validation Postman, Swagger and SoapUI 🔹 Defect Management Reproduce and investigate defects Document clear reproduction steps Capture screenshots/evidence Identify affected workflows Retest fixes Regression testing Jira/Azure DevOps defect tracking 🔹 Web Application Testing I have experience testing business-critical applications and workflows across areas including banking, lending, fintech, retail, travel, hospitality, and enterprise systems. How I approach testing I don't simply execute a checklist. I first understand the requirement, user journey, business rules, and system flow. From there, I identify the main scenarios, negative cases, boundary conditions, integration points, and regression risks. If something is unclear, I raise questions rather than making assumptions. When I find a defect, I provide clear steps, expected vs. actual results, supporting evidence, and enough context for the development team to investigate efficiently. Tools Test Management: Jira, Azure DevOps, Xray API Testing: Postman, Swagger, SoapUI Automation Exposure: Playwright, Selenium, Cypress Technical: JavaScript, TypeScript, Python, JSON, XML I also recently completed Playwright automation training and continue developing my automation skills while maintaining a strong foundation in manual and functional QA. What you can expect from me ✔ Detail-oriented testing ✔ Clear and actionable defect reports ✔ Strong understanding of business workflows ✔ Practical API and integration testing ✔ Independent work and reliable communication ✔ Collaboration with developers, BAs, Product Owners and stakeholders ✔ Focus on finding issues that can affect real users If you need someone to test your application, validate a new feature, investigate bugs, perform regression testing, or assess your API/integration flows, I can help. Send me your requirements, user stories, test cases, or application details and I can start from there.
