For the master project which spanned the whole study period, my fellow student and I developed a full-stack app for scanning and automatically storing invoices. The app is based on Flutter in the frontend and Strapi in the backend. We followed Clean Architecture principles and integrated CI/CD for seamless updates. Quality was ensured through test automation. Additionally, we implemented custom AI using LayoutLMv3 transformer for visual and textual document recognition and used Google ML Kit for accurate OCR functions.

Summary

  • I have been working in software development for over 5 years and have spent the last two years intensively dealing with Flutter and Dart. For backend work, I prefer using Node and TypeScript. Beyond pure development, I have an eye for DevOps - from system integration to deployment and maintaining solutions. Security is also paramount; I always rely on trusted practices and technologies to protect data and applications. 
  • Thanks to Flutter, I can create apps for various platforms including iOS, Android, Windows, MacOS, Linux, and the Web. I continuously learn and am always excited about every new project that offers fresh challenges and learning opportunities. Specializing in guiding projects from conception to implementation, my strength lies in bespoke development and close collaboration with my clients. 
  • As a freelancer, my goal is to provide custom and future-proof solutions tailored to my clients' needs. I'm particularly passionate about making tech language comprehensible, bridging the gap between vision and reality. 
  • In my free time, I love to travel and enjoy working from various locations, with co-working spaces often being my favorite spots. Sports, especially fitness, keep me in shape, while playing music provides the perfect balance to my digital routine.
