BACKGROUND

I'm a Technical Designer with 4+ years of experience bridging gameplay programming and systems design in Unreal Engine 5, C++, and Blueprint Visual Scripting. I specialize in building scalable gameplay systems, data-driven content pipelines, and AI behaviors that are easy to tune and extend without touching the codebase. I recently completed my Master's in Expanded Media (grade 1.2) at Darmstadt University of Applied Sciences, and was recognized as Top Rated Plus on Upwork with a 100% job success score across four years of freelance work.

Vaporwave Skateboarding

"Vaporwave Skateboarding" is a vaporwave-inspired endless runner game for Android and iOS, commissioned by Star Computer Labs.

  • Role: Gameplay Programmer & Technical Designer

  • Main Contributions:
    • Shipped a commercial endless runner on Android and iOS as gameplay programmer and 3D artist on a 10+ person team
    • Built an audio visualization system using frequency modulation to filter the active background track into frequency bands and drive object scale in real time
    • Designed season pass progression, store economy, and character customization as interconnected live-service systems
    • Integrated third-party marketplace plugins for Google Play Games Services and Apple Game Center, modifying the plugin architecture in C++ where needed

  • Tools & Technologies: C++, Blueprint Visual Scripting, Unreal Engine, Visual Studio, Blender 3D, Krita, Substance Painter

Ascend

"Ascend" began as a VR traversal prototype and evolved into a complete stealth-action game for my Master's thesis. The full game features one blockout level combining traversal mechanics with stealth-based AI encounters, supporting both VR and non-VR platforms. The full source code is available here.

  • Role: Gameplay Programmer & Game Designer

  • Main Contributions:
    • Developed a complete VR and PC stealth-action game as Master's thesis, running both platforms from a single codebase with only three configuration changes between them
    • Designed and implemented a four-state stealth AI with a visible detection bar and tunable thresholds, so difficulty adjusts without touching the codebase
    • Authored narrative and dialogue, directed ElevenLabs voice-overs, and implemented checkpoint and sonar scan systems
    • Built traversal mechanics across six types including rope climbing, ziplines, balance beams, and elevators, each adapted for both VR and PC interaction models

  • Tools & Technologies: Blueprint Visual Scripting, Unreal Engine 5, Blender 3D, Krita

Preview image for the Survive & Fry game

Survive & Fry

"Survive & Fry" is a cooking game developed for GitHub's Game Off 2023. I served as the Game Designer and Gameplay Programmer. The game draws inspiration from Overcooked, but with a unique twist, where players cook meals to cure zombies instead of escaping from them. The full source code is available here.

  • Role: Gameplay Programmer & Game Designer

  • Main Contributions:
    • Designed and shipped a cooking game for GitHub Game Off 2023 in C++ on Unreal Engine 5 within a one-month deadline
    • Built a preparation pipeline where players chop vegetables, combine ingredients, add an antidote, and scale the portion before serving
    • Ingredient types are defined in a DataTable, adding a new ingredient requires a new row and six lines of code with no changes to validation or interaction logic
    • Shipped with no visible bugs, praised by the community for being smooth and well crafted

  • Tools & Technologies: C++, Unreal Engine 5, Visual Studio

The Explorer

"The Explorer" is an accurate, explorable 3D rendition of our solar system, created using real public data from NASA and high-quality textures from SolarSystemScope. The project aimed to make learning about the solar system both fun and visually engaging. Background music was sourced by PurplePlanet.

  • Role: Technical Designer & Developer

  • Main Contributions:
    • Built a data-driven 3D solar system where all planetary content is authored through CSV, adding a new planet requires only a new row and a material setup
    • At runtime the system reads the CSV to spawn navigation buttons, populate info panels, and define camera interpolation paths with no hardcoded content
    • Camera interpolation travels between bodies using coordinates defined in each CSV row, communicating solar system scale through movement
    • Designed the information architecture and navigation flow to make complex planetary data intuitive and engaging for a general audience

  • Tools & Technologies: Blender 3D, Krita, Blueprint Visual Scripting, Unreal Engine 5

Range

"Range" is a Virtual Reality shooter prototype developed independently. I managed all aspects of the project except for the gun assets, which were sourced from the Unreal Marketplace and extensively modified for VR use.

  • Role: Designer & Developer

  • Main Contributions:
    • Built a VR shooter prototype around a master weapon class with Blueprint-exposed properties for mesh, audio, damage, ballistics, magazine, and effects
    • New weapon types are created by overriding only what differs in a child class, no code changes required
    • Designed physical VR interactions including weapon grab, two-hand grip, manual magazine reload, and per-weapon haptic feedback
    • Built a timer-based practice range with static and moving targets and personal best tracking

  • Tools & Technologies: Blueprint Visual Scripting, Unreal Engine 5, Blender 3D, Krita

XRiddle

"XRiddle" is an Augmented Reality project exploring the coexistence of AR Foundation Framework and Vuforia's Image Tracking API within a single Unity application through controlled lifecycle isolation. Target images were sourced from Unsplash. The full source code is available here.

  • Role: Designer & Developer

  • Main Contributions:
    • Combined AR Foundation plane detection and Vuforia image tracking in a single Unity application by keeping ARSession active and toggling only VuforiaBehaviour and ARPlaneManager between modes
    • Implemented canvas reparenting to prevent Vuforia's DefaultObserverEventHandler from deactivating tracked UI when a target is lost
    • Designed a two-mode AR experience where image targets trigger puzzle content and surface detection handles world placement
    • Shipped on Android with an iOS-ready architecture

  • Tools & Technologies: C#, Vuforia, AR Foundation, Unity3D, and Visual Studio
