From idea to MVP, I help clients turn concepts into fully functional services capable of handling thousands of users without performance loss. My focus is on flexible architecture, intuitive UX/UI, and clean, maintainable code. I use modern technologies like React, Next.js, Node.js, Nest.js, PostgreSQL, and AWS to deliver secure, stable, and fast solutions that can evolve with your product. 🛒 E-Commerce Solutions I design and develop e-commerce systems that help brands sell more and scale faster. Whether it’s an online store or a custom marketplace, every project is focused on conversion, performance, and ease of management. I leverage a headless commerce approach with tools like Strapi, Shopify Hydrogen etc - giving clients full control over content and flexibility for growth. I optimize for speed, SEO, and integrate with payment gateways, CRMs, analytics, and marketing tools. ⚙️ Web Applications I develop web applications that combine functionality, performance, and usability. From dashboards and internal tools to CRMs and custom business systems — my goal is to build fast, secure, and intuitive products that solve real problems. I follow best practices in UI/UX design and use technologies such as React, Next.js, TypeScript, GraphQL, and REST APIs to create dynamic, maintainable, and scalable applications. 🌐 Web Platforms I help businesses create complete web platforms - ecosystems that connect multiple services, users, and business processes in one place. Whether it’s a marketplace, learning management system, community portal, or corporate hub - I handle both front-end and back-end to ensure consistency, security, and scalability. Each platform is built with future growth, integrations, and analytics in mind. 🧩 Headless Architecture I work extensively with headless architecture, building fast, flexible, and modern sites and applications without the limitations of traditional CMS. Using an API-first approach, I connect content, commerce, and third-party services seamlessly. This method provides flexibility, decoupled development, and easier scaling — perfect for businesses aiming for performance, customization, and exceptional user experience. 🤖 AI Integration I integrate AI-powered solutions into web products to enhance performance and deliver smarter user experiences. Using OpenAI, Google Vertex AI, and other tools, I help automate processes, generate content, analyze data, and build intelligent features like chatbots, recommendation systems, or smart search. My goal is to turn AI from a “cool feature” into a real business advantage. 𝐓𝐮𝐫𝐧-𝐤𝐞𝐲 𝐰𝐞𝐛 𝐝𝐞𝐬𝐢𝐠𝐧 𝐚𝐧𝐝 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 𝐚𝐫𝐞 𝐜𝐫𝐞𝐚𝐭𝐞𝐝 𝐡𝐞𝐫𝐞: My team includes a 𝐔𝐈/𝐔𝐗 designer.

Services I provide: 📲End-to-End Product Design (SaaS & Mobile): Turning complex ideas into clear, profitable user experiences. 🔎 UX Audits: Identifying the exact friction points where you are losing money. 📐 Scalable Design Systems: Building the foundation so your team can ship features 2x faster in Figma. 🏁 Prototyping & Validation: Functional prototypes that look and feel like the real thing before a single line of code is written.

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!
