I'm Erfan Hosseini

I build conversion-focused websites that turn visitors into customers

Front-end developer based in Lisbon • QA engineer background • Enterprise experience at Fabizi. I create landing pages and web front-ends for small-to-medium businesses that need results, not just pretty designs.

From QA Engineer to Business-Focused Developer

My journey started in QA engineering, where I learned to think like users—spotting problems before they happen and understanding how real people interact with interfaces. This experience became my superpower when I moved into front-end development.

Currently, I work at Fabizi (food-tech), gaining rich experience in enterprise-grade interfaces. But as a freelancer, I focus on web front-ends and landing pages for small-to-medium businesses across industries—helping them convert visitors into customers.

What makes me different? I combine QA precision with business thinking. I don't just build beautiful websites—I create conversion-focused interfaces that support your growth goals. Every project gets the same attention to detail I learned in enterprise environments.
