Mid-level Unity Game Developer & Game Designer specializing in mobile and educational games

Málaga, Spain5y exp

“Unity game developer who built the economic system for an idle game (Hospital Empire), using spreadsheet-driven planning and iterative stat tuning to shape player feel. Has experimented with multiplayer networking via Mirror on an FPS prototype and uses GitHub Copilot to support modular/OOP-oriented planning and implementation; prefers remote/flexible work.”

“Frontend-focused contractor who contributed to Manitoba Hydro’s digital transformation by helping build and document an accessible design system with WCAG standards baked in, improving team efficiency through reusable components. Also delivered a Webflow CMS-driven Capoeira site (dynamic events/profiles) and shipped updates iteratively under tight timelines with strong QA and accessibility practices.”

“Unity/C# gameplay programmer with professional experience at Fabwelt Studios on the play-to-earn title "Arsenal," implementing player mechanics, interaction systems, and event-driven gameplay features. Also built a research-focused Tetris prototype as a master’s thesis, adding seedable RNG controls, data logging, and a playtest harness to study how randomness affects player perception.”

Junior UX Designer/Developer specializing in web and AI-driven portfolio experiences

1y exp

“Product/UX designer with strong front-end engineering capability who builds and deploys functional prototypes (React, Tailwind, Vercel) and bridges design-to-code via tokenized design systems. Has designed an AI-driven e-commerce fit/3D scanning experience (progressive disclosure, stress-map feedback) and is currently digitizing mass-casualty incident triage with haptics and spatially consistent, non-visual interactions to reduce medic distraction and error under extreme stress.”

“UI/UX Team Lead who built a design system from the ground up for Find Me (mobile + responsive web), focusing on reusable components, Figma variable-based workflows, and high-fidelity cross-functional handoff. Also designed an AI-driven predictive weather/travel comparison experience that simplifies complex climate data via a comparison model and layered UI, and uses prototyping to validate flows and catch issues early.”

“Robotics-focused engineer with hands-on experience building a lab robotic arm, combining software engineering with circuit design and hardware integration (DC motors, Raspberry Pi, gamepad control). Has worked on mapping (GMapping) debugging and implemented MQTT-based communication between Raspberry Pi and ESP32, plus used MATLAB/Simulink to simulate STM32 behavior for system-level testing.”

“Technical Game Designer on TimeSplitters Rewind who owned multiple Challenge Mode maps and shipped modes like stealth-focused “Infiltration” and “target practice,” handling AI placement/pathing, validation logic for multi-mode compatibility, and playtest-driven tuning. Currently prototyping a UE5 Blueprint-driven brawler with class systems, spawners, and Behavior Tree iteration (fear/roaming) over a fast two-week development loop.”
