About
Based in Zurich, I help businesses improve existing websites and SaaS interfaces by combining practical front-end understanding with user-focused functional QA. I’m the founder of KC WEB and WE FAST, and I work on responsive business sites, e-commerce journeys, registration forms, and dashboard-style experiences—always with clear navigation, reliable states, and smooth user flows.
I approach each project with a structured mindset: audit what’s broken or unclear, prioritize the most impactful fixes, implement or coordinate improvements, and then validate links, forms, responsiveness, and key journeys before release. From UX/UI consistency and information hierarchy to basic SEO and Lighthouse checks, I aim to deliver tangible quality upgrades and simple, confident user experiences.
