I’m a manual QA tester with hands-on experience testing web and mobile applications, focusing on user flows, UI behavior, and edge cases to ensure products work as intended.
I’ve completed multiple QA projects on Upwork with 5-star feedback, helping clients identify functional issues, inconsistencies, and usability problems before release.
My testing approach includes functional and exploratory testing, mobile vs web consistency checks, and validating expected vs actual behavior. I document findings with clear reproduction steps, screenshots or recordings, and concise summaries so developers can quickly understand and fix issues.
I’m comfortable reviewing designs (e.g., Figma) against implementation, testing real user scenarios, and creating structured checklists or test notes. My goal is simple: make issues easy to reproduce and easy to fix.
If you need a reliable tester for short-term testing, regression checks, or validating new features, I’m happy to help.

I've been a professional software developer and business owner for nearly 20 years so my experience is quite broad. I'm not just a developer though, I will look at commercial viability and can use my experience of managing people and supporting company-wide systems to apply business sense to my solutions.
I particularly enjoy working for small businesses where I can design the full solution, I can a manage integrations across a wide spectrum, everything from Google Sheets to Salesforce. I've worked with countless tools such as MailChimp, Retool and Shopify and can generally navigate around any tool that you need.
For the last 2 years I've specialised largely in Retool applications but with the progress in AI capability with tools like Claude, I've now moving away from low code and back into custom development using Next.js, Vercel and Supabase as it's just so fast.
I do have ethical standards though so please don't come to me with any dodgy scraping / bot type work as I have no intention of making the internet any worse than it already is :)
