Since 2003, I've helped companies improve digital products by making them easier to understand, easier to use, and more effective for their business. Today my work focuses on UX Audits, Customer Journey Analysis, usability improvements, onboarding optimization, and identifying product friction that prevents users from reaching value. I investigate how a product actually works from a customer's perspective, from the first landing page visit to onboarding, activation, and conversion. My goal is to identify where users become confused, lose trust, abandon the journey, or fail to complete key actions, then provide clear, prioritized recommendations that your team can implement. My audits typically cover: • Landing pages & messaging • Sign-up & onboarding flows • Customer journeys & user flows • Navigation & information architecture • Forms, dashboards & operational workflows • Mobile & desktop usability • Product friction & conversion barriers Recent experience includes improving SaaS, healthcare, transportation, and enterprise products. Route One Group (Transportation SaaS) Product Design Lead responsible for operational UX across a fleet management ecosystem used by 10,000+ commercial drivers. Designed workflows for ELD compliance, driver onboarding, fleet operations, billing, and dispatch, helping simplify complex business processes and reduce compliance violations by approximately 40%. Omio (Independent UX Audit) Conducted an independent UX audit of Omio. Produced a 10-page investigation report with annotated mockups, structured around Problem → Impact → Recommendation. Identified UX, visual, navigation, and journey friction issues with prioritized improvements. Sizov Report (B2B Analytics Platform) Investigated the trial request and onboarding journey for an institutional market intelligence platform. Redesigned qualification, email verification, and activation flows to reduce friction while preserving lead qualification and business control. Aesthetic Record Redesigned appointment scheduling and operational workflows for a healthcare platform. Simplified complex multi-step interactions and reduced booking time by approximately 50%. MedNote Designed onboarding and information architecture for a healthcare application managing family medical records. Created multiple user paths for different use cases while reducing cognitive load during first-time use. If you're getting traffic but users aren't activating, converting, or completing key actions, I'll help identify what's slowing them down and provide practical recommendations focused on business impact, not just design opinions.

I help B2B SaaS companies hit consistent revenue growth through high-converting marketing sites in Webflow and Next.js, built with technical SEO at the core. From UX strategy and Figma design to full Webflow or Next.js + Tailwind execution, I work end-to-end without handoffs, so your team moves fast and the site actually ships, with no endless revisions and no bottlenecks. 🚀 16+ years of experience 🖥️ 150+ websites shipped across SaaS, AI, and B2B tech 📈 Trusted by funded Series A–B teams across the US, UK, and EU "Ed is fantastic! He deeply understands how to structure a website to maximize conversion rates. I am so glad I got to work with him and I can highly recommend him to anybody else who needs UI/UX expertise." — Justin Baker, Founder ✅ WHY MARKETING TEAMS CHOOSE ME 1️⃣ SEO-First, Not SEO-Afterthought Most web design agencies and Webflow development shops bolt SEO on after launch, while I build technical SEO into the foundation from the first line of code: semantic HTML, Core Web Vitals, schema markup, internal linking, and an editable CMS structure that ranks and scales. 2️⃣ Diagnosis Before Execution I start by identifying what is actually blocking conversion or rankings, not by jumping straight into design. You get a clear fix plan with specific priorities before any pixel moves. 3️⃣ Strategy + Design + Execution in One Person I bridge business goals, ICP messaging, Figma design, and Webflow or Next.js delivery without briefing three different vendors or losing context between strategy and final build. 4️⃣ Conversion-Driven, Not Trend-Driven I build websites like sales assets, with clear hierarchy, positioning that resonates with your ICP, and conversion structure that drives demos and signups. 5️⃣ Founder and Marketing-Friendly Process I run async onboarding with clear milestones, no meeting overload, and a single Loom walkthrough when clarity is needed, so you stay focused on pipeline while I handle delivery. 6️⃣ Built to Perform and Scale I optimize every build for load speed, technical SEO, and internal team editing using Client-First methodology, so your team can edit and onboard new developers without restructuring from scratch. 7️⃣ AI-Ready Design System I build sites with a tokens.json source of truth, a synced live style guide, and Claude Code integration via SKILL.md and CLAUDE.md, so your team ships on-brand pages without waiting for design 🛠 SERVICES & SOLUTIONS ✅ Conversion & Credibility Breakdown I deliver a website and funnel teardown with a prioritized fix plan that identifies exactly what is blocking conversions or rankings. Delivered in 5–7 business days via Loom walkthrough and Notion summary. ✅ Technical SEO Audit I conduct a full technical SEO audit covering Core Web Vitals, semantic HTML structure, schema markup, internal linking, and indexation issues. You receive a prioritized roadmap with specific fixes per page, ranked by impact. Delivered in 7–10 business days. ✅ Implementation Sprint (7–10 days) I execute 1–2 high-impact fixes fast, including landing pages, pricing pages, or key conversion modules. Design is completed in Figma, and the build runs in Webflow or Next.js + Tailwind, depending on your stack. ✅ Website Rebuild or Migration (3–5 weeks) I rebuild or migrate 5–10 pages with a full CMS, component system, and SEO-optimized structure built for long-term rankings. Scope includes Webflow rebuilds or full migrations to Next.js + Tailwind + Sanity + Vercel, with positioning review, narrative mapping, conversion copy, and team training. ✅ Content System Activation I set up programmatic SEO infrastructure with Sanity or Webflow CMS, including content templates, taxonomy structure, and internal linking architecture. Your team publishes new content without requiring engineering support on every post. ✅ Growth Retainer (Monthly) I handle ongoing design, development, and SEO requests for SaaS teams that need continuous execution without hiring an in-house developer or designer. Turnaround is 2–3 business days per request. 🔧 TOOLS & TECH Webflow Stack Webflow CMS · Webflow Logic · Webflow Localization · Client-First (Finsweet) · Finsweet Attributes · Finsweet CMS Library · Relume · Memberstack · Wized · Jetboost · FigJam · Figma Next.js Stack Next.js (App Router · Server Components · ISR) · Tailwind CSS · TypeScript · Sanity Studio · Vercel · Vercel Edge Functions · SEO and image optimization libraries Performance & Technical SEO Google Analytics · Google Search Console · Ahrefs · structured data · Core Web Vitals · Open Graph · sitemap and robots configuration · GTM · Hotjar SaaS Integrations HubSpot · Stripe · Auth0 · Okta · Calendly · Salesforce · Zapier · Make · Airtable · Wized · Xano · Shopify 🎯 READY TO BUILD A WEBSITE THAT WORKS AS HARD AS YOUR SALES TEAM?

B2B SaaS products get complex faster than their UX can keep up. Dashboards become overloaded. Workflows mirror backend logic instead of user behavior. Role-based systems confuse users instead of guiding them. AI-era chaos make the product hard to use. I help B2B SaaS teams — from early-stage startups to scaling platforms — restructure complex workflows, simplify dashboards, and turn overloaded products into scalable systems. Through UX architecture and AI-accelerated delivery, not just visual UI design. My core work: • B2B SaaS dashboards and admin panels (data-heavy, multi-role, decision-centric) • Complex workflow systems, onboarding flows, and permission-based navigation • Figma design systems built for scale — components, tokens, auto-layout, dev handoff • AI product UX — structuring AI-powered platforms and AI-native SaaS into usable, scalable products • Early-stage SaaS: rapid UX architecture for founders moving from MVP to market-ready product • Information architecture for CRM, ERP, FinTech, RegTech, healthcare, and operations platforms How I work: • Start with UX audit and information architecture — before touching screens • Wireframes → high-fidelity Figma → interactive prototype → developer-ready handoff • Design system extraction: if you have a chaotic Figma file, I turn it into a scalable, documented system • AI-accelerated delivery: architecture sprints completed 2–3x faster than traditional agency timelines • Async-first, milestone-based — clear reviews, no guesswork What clients say and see: • Top Rated Plus | 100% Job Success Score | 112+ completed contracts • FinTech, RegTech, healthcare, AI platforms, real estate, cybersecurity, ERP/operations software • Served early-stage startups (pre-seed to Series A) through to scaling B2B platforms • Clients use words like: "restructured the entire product flow", "finally made sense of our admin panel", "shipped faster after the design system was in place" • 200+ UX/UI and product design engagements delivered across complex B2B SaaS and data-heavy platforms as the founder of LeverageUX. • 175+ millions raised by founders with our design assistance • Our work helped founders to win deals with brands like Microsoft, Tesla, BMW, DHL and Visa, etc. If your SaaS product feels powerful but hard to use — send me: • A screenshot or Loom of the problem area • What your users are confused about or where they drop off • What "done" looks like for this engagement I will tell you within 24 hours whether it's a quick fix or a structural problem — and what the right approach is. _________ Last updated: 15.05.2026
