I’m a Webflow Developer with 10+ years of experience in front-end development and web design. I started my career building complete websites from concept to launch, combining website design, front-end development, and technical implementation. Today, I focus on Webflow design and development, from pixel-accurate Figma to Webflow builds to complete responsive Webflow websites designed and built from scratch. My work combines responsive Webflow development, clean Client-First structure, Webflow CMS, custom JavaScript, GSAP animations, technical SEO, and website performance optimization. Because I understand both web design and development, I can preserve the original creative direction while making practical decisions about responsive design, usability, performance, and maintainability. On clean Webflow builds, I target a 90+ mobile Lighthouse score. Before launch, I document how analytics, tracking pixels, chat widgets, and other third-party scripts affect Core Web Vitals. Webflow University credentials: Webflow 101, CMS, Layout 1-2, and Expert track. WEBFLOW SERVICES - Figma to Webflow development: responsive, pixel-accurate builds organized into a reusable Webflow style guide and scalable Client-First system. - Custom Webflow design and development: complete Webflow websites designed and built from scratch around your brand, content, goals, and references. - Webflow landing page design and development: conversion-focused structure, visual design, responsive development, clear calls to action, and reusable sections. - Webflow CMS development: Collections, Collection templates, dynamic content, filtering, CMS architecture, and scalable content management. - Webflow website design: page layouts, visual hierarchy, responsive behavior, reusable components, Webflow design systems, and style guides. - Custom JavaScript and GSAP animations: ScrollTrigger, ScrollSmoother, SplitText, FLIP, custom interactions, and advanced website animation. - Webflow website redesign and template customization: visual updates, brand alignment, responsive fixes, usability improvements, and CMS cleanup. - Responsive web design and front-end development: desktop, tablet, and mobile layouts with cross-browser testing and consistent behavior. - Webflow performance optimization: Core Web Vitals, LCP, responsive images, lazy loading, third-party scripts, and render-blocking cleanup. - Technical Webflow SEO: schema markup, semantic HTML, Open Graph, redirects, sitemap configuration, and on-page technical setup. - Webflow migration: moving websites from WordPress, Wix, or Squarespace while preserving content, URL structure, redirects, and essential SEO settings. - Webflow maintenance and integrations: new pages, CMS updates, responsive fixes, forms, analytics, tracking pixels, HubSpot, Zapier, Make, and lightweight API integrations. WHY CLIENTS WORK WITH ME - I understand both web design and front-end development, so design decisions remain realistic, responsive, and maintainable. - 10+ years of front-end experience means I’m not limited by Webflow’s native features when custom HTML, CSS, or JavaScript is required. - I can follow an approved Figma design precisely or take responsibility for complete Webflow website design when no final mockup exists. - Custom GSAP animations and Webflow interactions are written in maintainable code and tested across desktop and mobile devices. - I explain how third-party scripts affect Core Web Vitals instead of promising unrealistic Lighthouse scores. - My experience with conversion-focused websites helps me think about structure, messaging, visual hierarchy, calls to action, and user flow. - My async-first workflow includes written updates, clear milestones, staging links, and documented decisions. - Clean Client-First handover allows your team to edit Webflow CMS content, update pages, and create new sections after launch. RECENT WEBFLOW PROJECTS Luxury real estate Webflow website: custom website design support, responsive Webflow development, GSAP ScrollTrigger animations, Webflow CMS, technical SEO, and performance optimization. Modular homes marketing website: conversion-focused Webflow design, CMS catalog, Client-First structure, reusable components, and responsive development. Webflow template customization: brand and visual updates, GSAP FLIP animations, responsive fixes, CMS cleanup, and Core Web Vitals optimization. HOW WE’LL WORK You share your Figma design, existing Webflow website, references, or project brief. I review the scope, provide a clear plan and milestones, then build in stages: style guide, responsive layout, Webflow CMS, custom animations, performance optimization, and technical SEO. You review each major stage before launch. Send me your Figma file, current website, or project brief. I’ll review the scope and respond with a clear Webflow implementation plan.
