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 a senior software developer from Portugal with more than 20 years of experience building commercial desktop and mobile applications. I help teams build, stabilize, refactor, and extend products that involve real technical complexity. My work is focused on desktop and mobile software where senior technical judgment matters: Qt/C++ applications, native iOS and Android apps, performance-sensitive features, media and audio/video pipelines, computer vision, hardware integration, OS-level behavior, and long-term maintainability. I have worked on commercial products used by real customers, including projects such as Rocketbook - Document Scanning, Triller - Music Video Social Network, ROVR Radio - Audio Production & Dashboard, Toby - AI Real-Time Audio Translation, iContact - Camera Widget, VideoShop - Video Composition, iGreet - Augmented Reality Greeting Cards, LeanStreamer - Multiple Audio Encoding Streaming Tool, BigRoom - Automated AI Editor, and other desktop and mobile applications that required reliable implementation and careful technical decision-making. Clients usually hire me when they need help with: • building a desktop or mobile product properly from the ground up • refactoring an existing codebase without unnecessary rewrite risk • solving platform-specific issues that are blocking progress or release • implementing complex native features involving camera, audio, video, files, hardware, or OS APIs • improving architecture, maintainability, performance, and stability • adding senior technical depth to an existing team or codebase My core expertise includes Qt/C++, desktop software, native iOS and Android development, software architecture, refactoring, performance optimization, media processing, computer vision, and hardware or platform-level integration. I’m especially well suited for products that already exist and now need to be improved carefully. That may mean stabilizing a codebase, modernizing architecture, solving difficult technical issues, or extending the product in a way that remains clean and maintainable. I care about building the right foundation early, keeping the codebase understandable, and making technical decisions that still make sense in the long run. If your product already exists and needs senior technical help to move forward safely, I’d be glad to discuss it.
