I have brought here my biggest and favorite works
as a professional.

Engineering Health and Team Transformation

At Kaufland e-commerce GmbH, I transformed team collaboration and engineering health across cross-functional teams by implementing mentoring-based leadership, structured discovery processes, and enhanced code review practices. This strategic approach delivered faster project delivery velocity, reduced context switching, improved team satisfaction, and fostered a culture of architectural thinking and knowledge sharing.

Team Leadership

In my capacity as Head of Development, I successfully managed a global team of remote engineers, revolutionizing our development process with unified cycles and sprints, which markedly increased productivity and technological exploration.

Innovative Development of the ROOBEO Platform

Leading the development of the ROOBEO platform, I played a pivotal role in integrating cutting-edge technologies, enhancing business processes, and collaborating with product and business owners to secure our position at the forefront of the e-commerce solutions sector.
