Hire the Best Software Design Freelancers
in Portugal

You bring the idea. I turn your Figma design into a fully working Next.js, React, or HTML, CSS and JavaScript website that is clean, fast and ready for real users. ✅ UI UX designer who builds what she designs, no gap between Figma and code ✅ Full stack web developer across frontend, backend, and database ✅ Figma to React, Figma to Next.js, and Figma to HTML, CSS, JavaScript ✅ AI integration developer with hands-on LLM and vector database experience ✅ Responsive web design that works on every screen, every device ✅ Flutter app developer for cross-platform mobile and web ✅ HTML email signature developer for clean, responsive, cross-client compatible signatures I'm a full stack web developer and UI UX designer with a degree in Informatics and Computing Engineering. I work on the complete product, from wireframes in Figma to deployed web and mobile applications. Most clients come to me because they're tired of hiring a designer and a developer separately and watching things fall apart in between. I handle both, which means the frontend developer and the UI UX designer are the same person, and what gets designed is exactly what gets built. I work across frontend development in React, Next.js, Angular, and TypeScript, backend development in C#, .NET, Python, and C++, and mobile development using Flutter for cross-platform app development. I also do Shopify website development for ecommerce businesses that need a clean, conversion-focused store. On the AI side, I build AI-powered web applications with LLM integration and vector database development using QDrant, a niche stack that very few developers know well, which means less competition and faster results for the clients who need it. ✅ Industries I Have Worked With I've worked on projects across ecommerce, SaaS, and software products. This includes Shopify website development for ecommerce brands, SaaS dashboard developer work for startups building internal tools and client-facing platforms, and full stack web development for software businesses that need reliable, scalable web app development. I've also worked on AI-powered web application projects for teams integrating LLMs and chatbot development into their products. ✅ Tools and Technologies I Use For design, I work in Figma, from UI UX design and wireframes to full design systems and handoff-ready files. On the frontend, I use React, Next.js, Angular, TypeScript, JavaScript, HTML, and CSS. For backend and systems work, I use C#, .NET Framework, Python, and C++. My database experience covers MongoDB, PostgreSQL, and MySQL, and for AI integration developer work I use QDrant for vector database development. For mobile, I build cross-platform app development projects in Flutter. I also work with Microsoft Excel for data tasks and build professional HTML email signatures for individuals and teams. ✅ My Approach and What You Get Every project starts with clear questions so there are no surprises later. I give honest timelines, send updates as work progresses, and deliver organized, well-documented code that's easy to maintain. You get responsive web design that works across all devices, UI to code conversion that matches your Figma files accurately, and a full stack web developer who handles the whole project without you having to manage five different people. If something needs fixing, it gets fixed, no back and forth, no excuses. 📩 Let's Talk Send me a message with your project details and we'll figure out in one conversation if we're a good match.

I'm Oksana — a UX/UI Designer with a Software Engineering background and 3 years building end-to-end digital products. I've shipped 1,400+ screens across mobile apps and SaaS platforms, built complete design systems from scratch, and maintained a 100% Job Success Score across 29 contracts on Upwork. What that means for you practically: My Figma files are developer-ready from day one — auto layouts, components, variables, proper naming conventions, and clean layer structure. No back-and-forth, no rebuilding. My engineering background means I think in constraints, not just aesthetics. I understand how components get coded, which directly shapes how I build design systems and prepare developer handoff documentation. My workflow: I research before I open Figma. Every project starts with understanding your users, your competitors, and your product goals. I create wireframes and user flows to establish solid information architecture, then move into high-fidelity UI design. The result: intuitive, production-ready interfaces with full interaction design and responsive design across all breakpoints. I work best in ongoing collaborations where I become a reliable part of your product team. I'm comfortable working from a brief independently, communicating proactively, and hitting deadlines without hand-holding. What I bring to your project: Mobile app design (iOS & Android) — from onboarding flows to complex multi-screen user journeys. Web & SaaS product design — dashboards, portals, admin panels, B2B platforms. Design systems — scalable component libraries with tokens, variants, and auto-layout built for teams. UX audits & wireframing — heuristic evaluations with actionable redesign recommendations. Developer handoff — organized Figma files with specs, annotations, and assets ready for engineering. Recent work: Fealya — AI-powered wellness app (iOS/Android): 257 screens designed solo, complete design system with 8 personality-based color themes, semantic tokens, full component library, and automated developer handoff via Claude Code + Figma MCP. Fan Baits — B2C social platform: 1,150+ screens across desktop and mobile, rebuilt design system with 40 components and 148 variants using Figma variables. Tools: Figma (advanced — variables, Dev Mode, auto layout), Figma MCP, Adobe Photoshop, Adobe Illustrator, Framer, Webflow, Notion, Jira. If you need a designer who ships clean, buildable, developer-friendly interfaces and can grow into a long-term product partner — let's talk.
