About Me

    I am a passionate full-stack software engineer based in Berlin, Germany. With over a decade of experience, I've had the privilege of building and maintaining robust web applications for diverse industries, from fintech to transportation and healthcare.

    Throughout my career, I've developed a wide range of technical skills, including Python, Django, React, and Golang, and have worked extensively on microservices architectures and UI/UX implementations. I thrive on crafting solutions that enhance user experiences and streamline business operations.

    I've worked with amazing teams at Payla, Agile42, HelloFresh, The Silverlogic and more, where I've built everything from risk management systems to consumer portals and internal tools. Beyond my professional work, I love mentoring aspiring developers, contributing to open-source projects, and exploring innovative side projects like quiz apps and poker planning tools.

    I'm always excited to tackle new challenges and create impactful digital solutions. Let's build something awesome together!
