Kawsher was a great find. We brought him on for software QA and he delivered consistently for over a year, thorough, reliable, and easy to work with.
He caught issues early, communicated clearly, and never needed his hand held. Exactly what you want in a contractor: someone who takes ownership and just gets it done.
Would absolutely recommend him to anyone looking for a solid QA analyst. Thanks for the great work, Kawsher, you made our team better.

I partner with SaaS and digital product teams to identify and resolve critical defects before they ever impact production. My approach integrates structured manual testing, exploratory testing, API validation, comprehensive regression coverage, and targeted automation—all aimed at giving your engineering team the confidence to ship quickly without compromising quality.
What I Bring to Your Project:
𝗥𝗲𝗹𝗲𝗮𝘀𝗲 & 𝗤𝗔 𝗣𝗹𝗮𝗻𝗻𝗶𝗻𝗴 – Strategic test planning, risk assessment, and resource mapping to define the right balance of manual and automation testing.
𝗠𝗮𝗻𝘂𝗮𝗹 & 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 𝗧𝗲𝘀𝘁𝗶𝗻𝗴 – Comprehensive functional, regression, and exploratory testing executed through both manual techniques and automated scripts for efficiency and depth.
𝗖𝗿𝗼𝘀𝘀-𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝗖𝗼𝘃𝗲𝗿𝗮𝗴𝗲 – Cross-browser, responsive, and device-specific testing across web, mobile, and tvOS platforms, supported by automation where repetitive coverage is required.
𝗖𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝗨𝘀𝗲𝗿 𝗝𝗼𝘂𝗿𝗻𝗲𝘆𝘀 – End-to-end validation of payments, subscriptions, transactions, user permissions, and role-based access controls, combining manual scrutiny with automated regression suites.
𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆, 𝗗𝗮𝘁𝗮 & 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 – Data accuracy validation, OWASP ZAP security scanning, and integration testing, leveraging automation for continuous security monitoring.
𝗕𝗮𝗰𝗸𝗲𝗻𝗱 & 𝗔𝗣𝗜 𝗩𝗮𝗹𝗶𝗱𝗮𝘁𝗶𝗼𝗻 – Backend testing, API validation, and CI/CD pipeline integration using Playwright, Appium, JMeter, and Postman for robust automation, alongside manual exploratory checks.
𝗔𝗰𝗰𝗲𝘀𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗔𝘂𝗱𝗶𝘁𝘀: WCAG 2.1 and 2.2 compliance testing with ADA accessibility audits to ensure your website or application is inclusive, legally protected, and accessible to all users.
𝗥𝗲𝗽𝗼𝗿𝘁𝗶𝗻𝗴 & 𝗥𝗲𝗹𝗲𝗮𝘀𝗲 𝗥𝗲𝗮𝗱𝗶𝗻𝗲𝘀𝘀 – Clear defect reports with evidence and reproduction steps, fix verification, and a final release-readiness summary—backed by both manual test results and automation test executions.
I believe in keeping things practical. My process starts with understanding your product, its users, the technology behind it, and how you handle releases. That gives me the context I need to pinpoint the most valuable user journeys and the areas where defects could hurt your business most.
I'm also comfortable working with whatever tools you already use—Jira, Linear, TestRail, Slack, GitHub, or your Agile and release workflows.
To ensure my recommendations are truly relevant, could you share a little about your product?
I'd appreciate knowing your product type, the core user flows you prioritise, your technology stack, and any particular release challenges you're dealing with. In return, I'll give you a clear view of the areas I'd focus on first and the testing approach I believe would serve you best.
