Selected Work

Retain

Retain is an AI powered flashcard app that helps students learn faster by automatically generating flashcards from PDFs, images, handwritten notes, and more. It uses adaptive spaced repetition, personalized study plans, and supports modern card types like Cloze and Image Occlusion.
From the very beginning, I contributed as a UI/UX Designer by shaping the core user flows, designing the visual interface and component system, and ensuring a clean, intuitive learning experience across web and mobile. I collaborated closely with the development team to turn early concepts into a polished, user friendly product.

Solar Defense

SolarDefense is a space themed tower defense game where players must protect their own solar system from energy hungry alien invaders. The core objective is to defend a central star by strategically placing defensive structures on surrounding planets, combining classic tower defense mechanics with orbital positioning and upgrades.
Beyond combat, SolarDefense features a light economic simulation that requires players to manage planetary resources while expanding and upgrading their defenses. With lasers, EMPs, and increasingly challenging enemy waves, the game rewards smart planning, efficient resource management, and long term strategy.

CityScaper

Pelicad, formerly known as CitySpacer, was one of the early augmented reality applications designed to make urban planning tangible and accessible. By overlaying planned buildings and infrastructure directly into real world environments, the app allowed citizens to experience future city spaces before they were built. This approach helped bridge the gap between municipalities and the public, strengthening communication, transparency, and civic participation.
The project gained significant public attention and became widely known through its appearance on the German TV show equivalent Shark Tank *Die Höhle der Löwen*. As part of the team, I contributed to the UI/UX design by crafting intuitive user flows, designing clear AR interactions, and ensuring that complex planning data could be understood easily by both citizens and public authorities.

Solaga

Solaga is a biotechnology company focused on developing scalable algae based technologies for sustainable CO₂ capture and biomass production. By leveraging the natural efficiency of microalgae, Solaga creates solutions that combine renewable energy, biotechnology, and circular economy principles.
As a UI/UX Designer, I supported the communication of complex biotechnological processes through clear interfaces and visual systems, helping translate scientific innovation into an accessible and credible digital presence.
