• Associate · KoreKontrol Germany GmbH2015-07-01 –

  As a UI and front-end associate at KoreKontrol, my role is varied and includes a range of skills and responsibilities. These involve developing bespoke e-commerce software using Spryker OS and Symfony, researching and optimizing user experiences for our corporate clients, managing high-scalability cloud clusters through the use of AWS, Kubernetes and Rancher, providing IT operations and cloud systems engineering services using Docker and Kubernetes, overseeing the preparation of technical specifications and project management, as well as building cloud-based CI/CD pipelines with Kaniko and Jenkins.

• Software Engineer · siroop2016-02-01 – 2018-04-01

  At Siroop, I developed RESTful microservices with Spryker OS and Symfony using test-driven development in a CI/CD environment, while migrating a monolithic architecture to a scalable cloud solution. I also created front-end tracking scripts with Tealium, collaborating closely with cross-functional teams and maintaining thorough technical documentation to uphold high-quality standards. These efforts streamlined the e-commerce platform’s performance, enhanced user experience, and ultimately improved business outcomes.

• Senior UI/UX Designer · Delivery Hero2014-04-01 – 2015-05-01

  The primary challenge of this project was the consolidation of Delivery Hero's extensive portfolio of brands, each distinguished by unique visual identities, user experiences, and business processes. Operating in over 50 countries, the project required addressing diverse market conditions and user preferences, making the task particularly complex. Delivery Hero operates in the dynamic q-commerce (quick commerce) sector, which focuses on rapid delivery of goods, including groceries. This industry relies heavily on innovative technology, logistical efficiency, and data-driven decisions to ensure near-instant deliveries. The constant need to adapt to evolving consumer expectations creates opportunities for advanced user experience solutions.

• Senior UX/UI Designer · Kiveda Holding GmbH2013-01-01 – 2014-01-01

  As a member of the design team at Kiveda, my role has important impact on the growth of the company. From the day-one, I focused on harmonizing the 3D configurator, the e-commerce platform, and offline consulting services into a single, cohesive journey. A core objective was to enhance user interaction while maintaining visual consistency across every touchpoint—from complex online customization to in-person assembly support. Cooperation with a multidisciplinary team was key to refining the design process. By gathering data-driven insights through research, we ensured each decision aligned with real user behaviors and preferences, finally guiding the creation of new UI components and improving the flow of the entire platform.

• Web Design Expert · Rocket Internet SE2011-08-01 – 2012-11-01

  At Rocket's core team, my primary objective was to create a scalable design system that would serve Rocket Internet’s rapidly expanding portfolio of e-commerce ventures. The system needed to support a diverse range of brands, ensuring consistency in user experience while allowing for region-specific adaptations. The challenge was to establish a design foundation that could be efficiently implemented across multiple platforms, with minimal friction during localization efforts. A modular approach was adopted, leveraging atomic design principles to ensure flexibility. Components such as navigation elements, product grids, and checkout flows were standardized, allowing for quick assembly and adaptation across brands. The system was data-driven, with continuous user testing through tools like Optimizely and Axure, ensuring that all design choices were validated by user feedback before being deployed globally.

• Web Designer | Front-end Developer · PEQU.design2007-03-01 – 2012-10-01

  Before I ventured into product development, user experience, interface design, and eventually full-stack programming, it was my childhood fascination with computer graphics and illustration that truly set the stage for a creative journey. At the start of the previous decade, the internet acted more like a subtle appendage to integrated marketing rather than the central pillar it would later become. In that formative period, I embraced the role of an art director in an environment that sought to bridge time-tested advertising methods with emerging digital frontiers. Every project required a balance of conceptual art, consumer psychology, and technological savvy, blending imagination with the business realities of a transitioning marketplace.
