Let me tell you about myself

---

I'm a Senior Mobile Developer with over four years of experience working with .NET Xamarin, Swift/iOS, and Kotlin + Java for Android, plus an additional year in the JavaScript ecosystem using Vanilla JavaScript, TypeScript, Angular, Node.js, and Express. Before that, I spent around five years collaborating on web development projects using CMSs and no-code platforms such as Weebly, and more than ten years working in various roles within the communications and media sector.

As of autumn 2025, I've just launched my second app on the App Store, focused on improving my iOS development skills.

In September 2023, I joined Avenga as a Senior Mobile Developer for ProCredit Bank. As the most senior member of the frontend team, I took ownership of a large part of the project's visuals and user flows for a new instant payment module, ensuring compliance with country-specific requirements and delivery deadlines, while also managing all iOS tasks related to the App Store. After the first successful phase, two additional phases were added, and once those were completed, I also contributed to backend tasks in .NET. My contract ended in mid-2025.

In spring 2023, I started working at Capitole Consulting on Vueling's internal mobile app for their cabin crew, built with .NET Xamarin Native. This experience helped me deepen my knowledge of native iOS (Xcode) and Android (Android Studio) design and architecture, particularly on iOS. Unfortunately, after nearly four months, my contract ended.

Back in November 2020, I joined EricSports, where I first worked on EricBoard, a 2D/3D online whiteboard for sports professionals developed with Three.js. The tool was nearly finished but required significant refactoring and usability improvements before release. I implemented new features, fixed bugs, and optimized performance, contributing to a successful launch that quickly attracted hundreds of users. Afterward, I moved to the EricOne suite to work on EricVideo, a cross-platform video analysis app for coaches. There I rapidly upskilled in .NET/C# and Xamarin.Forms, collaborating across the team on development, builds, and multi-platform deployments, especially for iOS. The product launched successfully a year later, and I continued improving and extending its functionality for a second version before transitioning out of the company in early 2023.

Before becoming a developer, I spent over a decade as a freelance professional in journalism, video production, and post-production, working on projects for international brands such as Docker, Netlify, Qualcomm, and Roche. Around 2016, I started exploring web development, initially focusing on content and design, but soon became passionate about programming. In mid-2020, I completed a Full Stack Bootcamp and began developing websites using JavaScript and later the MEAN stack (MongoDB, Express, Angular, Node).

I'm passionate about continuous learning and improving through real projects. People who have worked with me describe me as honest, focused, and persistent. I tend to be a bit of a perfectionist — sometimes at the cost of speed — but I always strive to balance quality and deadlines to deliver the best possible results.
