Flutter/Dart Enthusiast • Full-Stack Developer • Emergency Medical Responder • Deputy Unit Leader (Emergency Response Unit)

With over five years of experience as a Flutter developer and a broad tech stack (Flutter, Dart, JavaScript, TypeScript, Python, FastAPI), I deliver high-quality, user-centered mobile applications. My expertise in CI/CD, project management, and team coordination, combined with my passion for open-source projects, makes me a strong fit for innovative software development initiatives. My volunteer work as an emergency medical responder and deputy unit leader of the Central Emergency Response Unit in Ludwigsburg district demonstrates my ability to take responsibility and communicate effectively in critical situations.
