Part-Time Web App Tester needed

My team ships client-facing web applications every week and I need an experienced tester who can jump in on a part-time basis to keep quality tight release after release. You will own the entire test cycle for each build, running functional, usability and performance passes across the current browsers and devices we support. You’ll write lean test cases, execute them, log any defects with clear reproduction steps and evidence, then verify fixes before we push to production. I typically queue up two to three small releases a week, so expect roughly 10–15 hours of work spread across Monday–Friday; timing is flexible as long as critical issues are reported before the daily stand-up. Key deliverables for every sprint: • Compact test plan covering functional, usability and performance scopes • Detailed bug/issue list with screenshots, console/network traces or short clips • Final sign-off report summarising coverage, unresolved issues and performance metrics Please be comfortable with browser dev tools, responsive break-point checks and, when needed, quick scripts in Selenium or similar to repeat performance runs. Communication happens in Jira and Slack, and we review findings live during our weekly demo. If you have a knack for spotting edge-case flaws in web apps and can document them clearly and quickly, I’d like to keep you onboard long term.
