🐞 I find the bugs nobody wants to exist
I'm Luis Aranguren, a QA Engineer with 1 year of experience in manual and automated testing. My mission is simple: deliver software with no unpleasant surprises. I specialize in hunting bugs — both the obvious ones and those hiding in complex flows — so your product works right from the first click.
🔍 What I offer
• Manual exploratory testing: I put myself in your user's shoes to uncover usability, functionality, and logic issues before they impact your customers.
• Playwright automation: I turn repetitive tests into reliable scripts that run on their own, saving you time and ensuring critical flows never break.
• API testing: I validate that your web services respond correctly, using Postman to ensure solid integrations.
• Git version control: I manage your test code as part of the project, making collaboration and change tracking seamless.
🎯 Why work with me
• Passion for finding bugs: For me, every bug is a small victory. I don’t stop at the obvious; I love exploring, breaking, and documenting every last detail.
• Clear communication: I deliver detailed reports with reproduction steps, visual evidence, and suggestions for fixes.
• Result-driven mindset: I know the goal isn't just to report, but to help build a better product. I work with you to prioritize and understand the real impact of each finding.
