Manual QA tester and AI app builder helping you find bugs before release, improve user journeys, and turn an idea into a working web app. I bring 5+ years of hands-on manual testing and 18+ years in web delivery. MANUAL QA & SOFTWARE TESTING • Functional, regression, exploratory, smoke, cross-browser and responsive testing for websites, SaaS products and mobile apps. • End-to-end checks of signup, login, forms, dashboards, user roles, checkout and subscriptions — including test-card payments and failed transactions. • Test cases and release checklists based on requirements, real user journeys and edge cases. • Actionable bug reports: steps to reproduce, expected vs. actual results, environment, severity and screenshots. Retesting fixes and checking for regressions. • Usability testing and UI review against designs, with practical feedback for developers. AI APP BUILDING & VIBE CODING Since 2025, I have used AI-assisted development to build and release products. I can help scope an MVP, guide AI implementation, refine the interface, troubleshoot integrations, deploy and manually test the result. My projects use Next.js, Supabase, Vercel and GitHub, with Flutter/Android for mobile work. I combine product thinking, Figma and Adobe XD interface design, and careful release QA. Selected work in my portfolio: • Reachlyst — AI-assisted outreach SaaS and Chrome extension. • Webara — a web app for product decisions, using Next.js and Supabase. • KinOrbit — Android family location app, including permissions and release testing. • Cook From This / What to Cook? — Android recipe app with AI-assisted features. WORDPRESS & E-COMMERCE 15+ years with WordPress: WooCommerce, Elementor, theme customization, customer support, troubleshooting, migrations, performance improvements and compatibility testing. My earlier work with the Pebas team contributed to a commercial theme portfolio with nearly 17,000 ThemeForest sales and 30,000+ customer support requests handled — shared team results. TOOLS & DELIVERY Jira, Trello, ClickUp, browser DevTools, Figma, Adobe XD, WordPress, WooCommerce, Shopify and Webflow. Working knowledge of HTML/CSS and JavaScript/PHP; basic Postman and SQL. My QA specialty is hands-on manual testing. For a focused QA engagement, you receive a prioritized issue list, reproducible bug reports and a clear summary of what was tested and what still needs attention. For an app-building engagement, we agree on the user flows, scope and acceptance criteria before implementation. Based in Serbia (CET/CEST), available 30+ hours per week for ongoing work or a clearly scoped first project. Send me your product, current issue or MVP idea through Freelancer, and we can define the next step.
