Summary
With over 15 years of experience as a Senior Developer, I have developed a strong expertise in development and system administration, particularly in backend systems. My skill set includes software architecture, software and database development, operations, and quality assurance. Over the past 8 years, I have honed my leadership and project management skills. I am passionate about emerging technologies and excel at integrating them into client projects. My primary goal is to deliver solutions on time and within budget. I have successfully collaborated with esteemed clients such as Project A, Rocket Internet, ABOUT YOU, Axel Springer SE, kfzteile24, innogy, and Zalando.
I have over a decade of experience designing, building, and scaling software platforms across e-commerce, energy, and SaaS industries. As Lead Software Architect at Innogy SE, I drove the development of the “bliss” app from concept to deployment in just five months, managed cross-functional teams, and optimized infrastructure to cut deployment time by half. At Zalando SE, I redefined and rebuilt the returns process, delivering a scalable Kotlin/Java application that improved efficiency and customer experience. Previously, I led engineering at Zimmerli of Switzerland, boosting store performance by 30% and user engagement by 15%, while planning roadmaps and managing international teams. My roles at Travojo, tausendkind, blogfoster, About You, Project A Ventures, Rocket Internet, and Axel Springer further strengthened my expertise in backend and frontend development, system architecture, cloud infrastructure, and platform scalability, with hands-on use of technologies such as Java, Kotlin, Node.js, React, Kubernetes, AWS, Azure, and Postgres.
