UI/UX Designer | Mobile App Design | Web Design | Figma Expert | SaaS

👉🏼 Whether you’re building a mobile app, a SaaS tool, or a website, I bring clarity, structure, and conversion-driven UX/UI. 🔥 I design fast, clean, dev-ready flows and interfaces that help teams launch and scale. Before becoming a full-time UX/UI designer, I spent years building my own digital services, designing high-conversion websites, teaching entrepreneurship, and working in strategy and data analytics (including Deloitte). ⚡️ This gives me something most designers don’t have: product intuition, user psychology, and business-first thinking. 💡 I specialise in minimalist UX, structured flows, and polished UI that improve user understanding and business performance from day one. 🎨 What I Do 🔹 Mobile App UI/UX (iOS & Android) — onboarding, paywalls, activation flows, feature UX 🔹 SaaS & Web App UX/UI — dashboards, workflows, internal tools, AI tools 🔹 Web Design (Landing Pages & Marketing Sites) — conversion-focused (Elementor / Webflow) 🔹 UX Audits & Product Redesigns — identify friction fast and fix it 🔹 Design Systems — scalable components, consistent tokens, reusable patterns 🔹 Wireframes, Prototyping & User Flows — clear end-to-end journeys 🔹 Dev-Ready Figma Handoff — organized, component-based, easy for engineering ⭐ Clients describe my work as: “Strategic, fast, and incredibly well-structured.” — AI Decorator (Mobile App) “She distills chaos into clarity.” — VaultIt (Mobile App) “Her insights translate directly into revenue.” — Rod Wallace, PhD (Web) 💪🏻 Why Clients Work With Me ✔ Product thinking — shaped by entrepreneurship, analytics, and behavior psychology ✔ Conversion-focused UX — onboarding, paywalls, trial starts, retention loops ✔ Experience that goes beyond UI — I handle research, prioritization, UX, UI, & strategy ✔ Fast execution + clarity — clients consistently highlight how I simplify complexity ✔ Trusted collaborator — responsive, thoughtful, and proactive ✔ Business-first mindset — every design decision is tied to outcomes ✔ Dev-friendly files — structured components and clear handoff 💬 What Clients Say AI Decorator — AI-Powered Mobile App “Sofia was key in taking our AI Decorator app from idea to a polished, high-performing product… Her work on the onboarding flow and paywall directly contributed to us reaching a 15% initial CR on our first release.” VaultIt — Mobile App Visual Redesign “She’s not just a designer — she’s a strategic product thinker. Sofia took our app to a level we didn’t think was possible… She distilled chaos into simplicity and brought emotional clarity to the experience.” Mobile App Conversion Improvements “After implementing her proposal, our A/B test showed a 17% increase in initial conversion rate, which translated into a huge MRR uplift.” Conversion-Focused Website (Elementor) “YOU GET MORE SALES! Her insights are uncanny… Sofia identifies opportunities that turn visitors into engagement and then into revenue.” — Rod Wallace, PhD 💻 Industries I Work Best In Mobile Apps • SaaS • AI Tools • Health & Wellness • EdTech • Productivity Fitness • Lifestyle • Online Services • Digital Businesses 🛠️ Tools & Methods Figma • FigJam • Elementor • Webflow UX Research • User Flows • Behavior Psychology • Prototyping Design Systems • Wireframing • Interaction Design Conversion Optimization • Analytics • A/B Testing If you need clean, strategic, dev-ready UX/UI for your app, SaaS platform, or website, I’d love to help.
