I help businesses fix what's costing them conversions, then build the version that actually works. That means two things: I run structured UX and CRO audits that turn vague "something feels off" feedback into a prioritized, evidence-based report and I design and develop complete, production-ready websites in Framer, Webflow, and Wix Studio. Most people hire me for one or the other. Many end up using both, since the audit almost always feeds directly into the build. I'm Top Rated on Upwork with 50+ completed projects and an Awwwards Honorable Mention, and I work as part of a small agency team (a design lead and an automation lead) so larger projects get more hands without losing a single point of accountability. You're always working directly with me. UX & CRO Audits I audit sites the way a researcher would: heuristic evaluation, user flow mapping, friction-point identification, and competitor benchmarking, all tied back to your actual conversion goals rather than generic best practices. Recent audit work includes a full platform audit delivered as a 22-page report with interactive prototypes, giving the client both the diagnosis and a visual path to the fix. You walk away with a clear, prioritized list; what's broken, why it matters, and what to do about it not just a pile of opinions. - Where it applies: SaaS platforms, e-commerce, marketing sites, and lead-gen funnels. Web Design & Development I design and build complete websites end to end, from information architecture and visual identity through to a fully responsive, performant build. I work primarily in Framer, Webflow, and Wix Studio, and I've delivered everything from marketing sites and SaaS platforms to GoHighLevel funnels and editorial-driven layouts. Design and development happen together in my process, not as separate handoffs, so what gets built matches what was designed, no lost-in-translation gaps. If a project needs AI integration or automation (workflow automation, personalization, intelligent features), I bring that in when it genuinely improves the product, not as a bolt-on. Background 7+ years of design experience spanning editorial/print (large-scale publications, catalogs, packaging) and digital product design, with certifications in Branding & Typographic Communication (Domestika) and Grid, Layout & Color Mastery (Obys Agency). How I work I ask direct questions before I start about your users, your goals, and what "success" actually looks like for this project because the right answer usually isn't the first one you'd guess. I respond quickly, and if I'm not the right fit for what you need, I'll tell you honestly rather than take the job anyway. Glen
