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.”

“Unity/C# developer who built and continues to evolve a data-driven product configuration system for complex medical equipment—reverse-engineering undocumented, massive databases and generating 3D configured products with extensive rules—helping users (e.g., hospital sales workflows) save time and support increased sales. Also built an internal LLM-powered debugging assistant using structured Unity/backend telemetry and has hands-on Unity Netcode experience in smaller multiplayer prototypes.”

“Unity/C# developer who led an end-to-end refactor of a Duolingo-style gamified app’s core progression and UI system, redesigning architecture with MVVM/SOLID and event-driven UI updates. Delivered measurable performance improvements (rankings view from sub-35 FPS to ~55–60 FPS) plus draw-call reductions using UI Toolkit and sprite atlases. Also supported Photon-based VR multiplayer (Meta Quest) in an educational accident-simulator, focusing on real-time debugging and sync strategy.”

“Full-stack engineer who built an end-to-end healthcare logistics application on a Microsoft services stack, delivering Spring Boot microservices and a responsive React frontend. Strong focus on production concerns—API performance tuning (indexing/caching/pagination) and microservice reliability (timeouts/retries/circuit breakers)—with Dockerized deployments and standardized Jenkins CI/CD.”

“Backend/ML engineer with deep fintech and marketplace experience: built a real-time financial analytics + algorithmic trading platform (Python/Postgres/Kafka/Redis) and drove major DB performance wins (10x faster analytics; sub-10ms response consistency). Also shipped an end-to-end ML recruitment matching platform (scraping/ETL/modeling/Django deployment) with reported 92% matching accuracy, and emphasizes production reliability via monitoring, blue-green deploys, and robust workflow error handling.”

“Unity developer with hands-on experience evolving enemy AI from event-driven logic to FSMs and ultimately behavior trees, improving both performance and debuggability while making enemy reactions feel faster and more consistent to players. Has built multiple multiplayer games using Photon PUN 2 and Unity NetCode, focusing on server-authoritative synchronization and minimizing network traffic; also applies AI tools to accelerate prototyping and diagnose complex issues like OPC UA tag mismatches.”

Den Helder, Netherlands5y exp

“Unity game developer/designer who built the core combat, NPC, and player ability systems for an action game (MonstersVSZombies), including a mechanic where defeated enemies can be recreated as allied versions. Emphasizes modular, generic C#/.NET architecture to scale content quickly, and has hands-on VR optimization experience (mesh/draw call reduction and baking lighting to improve FPS).”
