I'm a solo Dev. I have more than 9 years of experience in Mobile development and web development. I have been working with the cross-platform framework React Native for 6 years and am still working. This is my main stack right now. I use TypeScript and JavaScript to make React Native apps. I tried the Flutter framework back in 2020, and I like it. I now use Flutter to develop cross-platform applications, and I like it more and more. I feel that I will soon switch completely to Flutter only! Flutter is less of a headache :) Back in 2012, I started my career as a front-end web developer with JavaScript. Since 2015, I started developing for Android applications, and after a year of work, I bought myself the first MacBook to make native applications for iOS. Do you remember Objective-C? I do)) I'm interested in long-term customer relationships, so I am ready to participate in your project from idea to production and provide high-level support after delivering the main work. - I have been using FlutterFlow as well since 2023, and I like it.

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.
