Top Rated | 100% Job Success | 5.0★ on every rated contract | Senior Webflow Developer specializing in Figma-to-Webflow & Client-First architecture for agencies and tech companies. 100+ websites delivered for clients in the US, Canada, UK, Germany, Scandinavia and Australia. I build Webflow sites with a clean, scalable structure, so your team can add pages and content without breaking anything. Agencies and business owners come back to me because the work is reliable, clearly communicated and done right. 4 years focused exclusively on Webflow, 7 years in web design, and a marketing background before that. I know how a site is built, and how it's meant to work for the business behind it. I regularly work as a white-label developer for design and marketing agencies, delivering Webflow builds for venture-backed and enterprise-level companies in telecom, B2B SaaS, healthtech, fintech and retail. I stay available after launch for support and further development, so you never have to look for a new developer. "Exceptionally serviceminded and clever. Very easy to communicate with." — Client review ⚡ SELECTED WORK 📌 International bridal fashion label Ria Tener (long-term client, since 2019): full end-to-end redesign and build, from concept, copywriting and UI design to Webflow development. Complex B2B catalog architecture with 16 CMS collections, 300+ products, custom "Add to Favorites" functionality, advanced collection filtering and site search. The brand is retailed in 110+ bridal boutiques across 20+ countries. 📌 Multilingual eSIM platform (venture-backed telecom platform, through an agency): my role was Webflow developer on 50+ sites for different SIM providers, each branded to the provider. Up to 450 products per site, linked to countries and regions through a multilingual CMS. Zero errors on delivery was the core requirement. 📌 B2B SaaS procurement platform (venture-backed, through an agency): sole Webflow developer in a team of designers. I restructured the Resources CMS (URL logic, filtering, categories, redirects), built a reusable component system, fixed JavaScript errors and layout shift, and launched the rebrand with custom animations. 📌 Shopping center website (Germany): built in Webflow from the Figma design of a German agency's client. Store directory, events, blog, vouchers and site search on a CMS that non-developers can manage. Later extended with a WCAG audit and fixes, reaching a 90+ accessibility score. Repeat agency partner: 5+ further projects delivered since. 🛠️ WHAT I DO → Figma to Webflow development (Client-First, responsive, interactions, Swiper) → Website design and Webflow development, from landing pages to multi-page CMS sites, from concept to launch → CMS architecture: references, multi-references, filtering, search, 300 to 1000+ items → Custom features beyond native Webflow: favorites, advanced filtering and search (Finsweet or custom JavaScript) → Reusable component systems, so new pages ship fast and stay consistent → Member areas and gated content with Memberstack → Multilingual sites: native Webflow Localization, or a lightweight custom setup for smaller budgets → Migrations to Webflow from WordPress, Squarespace, HubSpot, Next.js and others, with SEO preserved → Accessibility (WCAG) audits and fixes, cookie consent and GDPR setup (Cookiebot) → Technical SEO basics on every project → Forms and Make automations (form-to-email, Google Sheets) → Post-launch support and updates 🤝 HOW I WORK I give honest scope and timeline estimates upfront, and I recommend what your project actually needs, not the biggest possible build. I keep communication clear, hand over a clean build with a recorded Loom walkthrough, and stay available after launch. I'm comfortable plugging into an agency's process and working under NDA, and I work best with agencies (white-label is welcome) and business owners who value quality work and good communication. 📩 Send me your project details and I'll reply with honest feedback on scope and timeline.
