🏅 4.8-4.81 App Store ratings, ⭐ 9.7/10 client satisfaction | ⚡ Written friction read within 24 hours | 📊 Every result shipped, not estimated | 🎯 WCAG 2.1/2.2 accessibility audits | 🚀 100+ projectssince 2017 MEASURED I am a UI UX Designer judged after launch: activation, task completion, retention, store rating. Every figure below carries a baseline and a shipped product, not a round number or an anonymous "Fortune 500 client". Named work: Logitech ($4.8B consumer tech brand) Luxoft (Technology company, 425+ global clients) Onyxia (cyber resilience, 40+ integrations) Housetable (renovation lending) Obviant (acquisition data) Nite Riot, CODE Furniture, Auxility - more under NDA. WHAT I DELIVER Most briefs reach me as one of these: Mobile UI UX Designer for an app rebuild, UI UX Web Designer for a site that doesn't convert, UI UX Designer SaaS Figma for an unreadable dashboard, UI UX Designer React when design and code have drifted apart, or product designer when the problem is the pricing model, not the screen. UI UX Designer Figma - user flows, wireframing, high-fidelity prototypes, token-based design systems on strict auto-layout, so AI-assisted dev turns Figma into code predictably. Every handoff carries states, interaction specs, and documentation. UI UX Designer SaaS - B2B dashboards, admin panels, onboarding, pricing and activation flows. A UI UX Designer SaaS brief starts at the funnel and information architecture, not the visual layer - dashboard design, data visualisation, usability testing. Mobile UI UX Designer - iOS and Android, consumer and clinical. Mobile app design, navigation, prototype testing, accessibility. Apps I've built hold 4.8 and 4.81 App Store ratings, 1,600+ reviews each. UI UX Web Designer - web design for SaaS landing pages, marketing sites, and web applications, plus wix web design and Shopify web designer work for platform-committed teams. A UI UX web designer ships responsive systems, not one-off pages. As a web designer in Figma or Webflow, I cover Figma web designer and Wix web designer handoffs, plus website development web design for WordPress teams needing a web developer's eye on migration. UI UX Designer React - token-mapped design systems, component specs, and variables named to match your codebase. It removes the translation layer between Figma and engineering. Graphic Designer - logo design, visual identity, colour palette, typography, brand guidelines. A reusable system, not one poster. WHERE I HAVE SHIPPED UI UX Designer Healthcare (patient/clinician, WCAG 2.1/2.2) UI UX Designer Crypto and fintech (payments, wallets) UI UX Designer CRM (records, pipelines) UI UX Designer Real Estate (proptech, lending) UI UX Designer AI (agent interfaces, approval gates) UI UX Designer Shopify (storefronts, checkout) Game UI UX Designer (HUD, menus) UI UX App Designer Arabic (right-to-left layouts) HOW I WORK 1. Audit behaviour before opening Figma: funnel data, clickpaths, support tickets, a task-flow walkthrough. Root cause is usually one step, not the product. 2. Restructure - information architecture and flow first. As a product designer, I'll tell you when the fix is sequencing, not pixels. 3. Design and hand off a Figma package: hierarchy, design system, states, edge cases, tokens, auto-layout. Developers shouldn't have to guess. 4. Measure. We agree the metric before I start and check it after launch. RESULTS, WITH BASELINES Healthcare platform (NDA) - onboarding completion 24.6% → 43.9%, a 79% relative lift. Clinician task cut from 11 steps across three views to 5 in one. CSAT 3.2 → 4.4. Fix: defer notification preferences, care-team invites, and goal-setting until after activation. Transcarent - 43% of members found lower prescription prices via the in-app matching flow. 4.8 App Store rating, 1,600+ reviews. Five care verticals unified into one needs-based navigation. Clair - 92% employer adoption across payroll partners, 4.81/5 across 1,600+ reviews, Top 100 in App Store Finance. Digibate - onboarding at 25.6% vs a 40-60% B2B SaaS benchmark, 30% lost at pricing. The audit changed the business model, not the screen: permanent Freemium to Free Trial. SmartTID - 210 success criteria audited against WCAG 2.1, 2.2, and EN 301 549, three environments, severity-ranked, delivered as VPAT 2.5. A landing page web design brief gets the same audit-first treatment: what's the website losing before redesigning how it looks - whatever the stack, Webflow, WordPress, Wix, or Shopify.
