I write a test plan covering scope, types of testing, environments, and priority bug areas. For web testing engagements this includes a browser and device coverage matrix. Week 2 onward: structured manual testing in your sprint cadence. Daily bug reports in your tracker. Regression testing after every release. API testing running in parallel with functional manual QA. Weekly QA summary reports for the engineering and product team. I ask before assuming and flag risks early. I overlap with EU and US business hours and respond within 4-8 hours during the working week. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE QA AUDIT - START HERE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Share your staging URL and a brief on the riskiest area of your product. I will run a focused manual QA pass, log the first bugs I find with full reproduction steps and severity labels, and send back a sample bug report and a test plan outline within 48 hours - no cost, no obligation. It gives you a clear picture of the quality of my manual testing work before any contract starts. Not at the testing stage yet? Share your product brief and I will send back a recommended QA approach and test coverage plan tailored to your stack and release schedule.

With 15+ years of experience in Software Quality Assurance, I've helped startups, SaaS companies, enterprises, and product teams establish scalable QA processes that improve software quality, reduce production risks, and accelerate release cycles. Throughout my career, I've partnered closely with founders, engineering managers, product owners, and development teams to build quality into the software development lifecycle rather than treating testing as the final step.
