I am a Godot Game Developer with a strong academic background in software engineering fundamentals. Unlike many hobbyists, I approach game development with rigorous logic, ensuring that your game's code is not only functional but also clean, scalable, and bug-free. Currently completing a Technical University Degree in Programming, I combine creative mechanics with solid architectural principles. My Core Expertise: Godot Engine (4.x): Proficient in both GDScript and C#. Game Logic & Physics: Applying university-level Math & Physics (Vectors, collision logic) to create smooth gameplay. Systems Design: Building robust systems for inventories, state machines, and save data (using my SQL/Database background). Code Quality: Strict adherence to OOP (Object Oriented Programming) and clean code practices. I am looking for opportunities to help indie developers and studios with prototyping, mechanic implementation, and debugging. I am a native Spanish speaker and fluent in English, ready to communicate clearly and efficiently. Let's build something solid.

I'm an Upwork member with 100% Job Success and Top Rated Plus Python and C++ programmer with extensive experience in sound, image and video processing. I have been working for a long time with the OpenCV, GStreamer and NVIDIA Deepstream SDK libraries, using GPU hardware with CUDA and other HPC libraries. My work experience includes professional video players & editors, transcoders (using different types of inputs, such Blackmagic Decklink capture cards and all the video formats: HLS, SRT, fMP4, WebRTC), DSP systems, JUCE framework, object detection and tracking, Deep Learning systems (YOLO, Pytorch, Tensorflow, TensorRT), AI hardware like NVIDIA Jetson Orin and Raspberry Pi devices. I have also experience in ultrasound signal processing. In ML and LLM models I'm working training Reinforcing Learning PPO models and LORA fine tuning methods on AI. Also I have experience with TTS and Speech Recognition systems using models like Whisper, WhisperX and PiperTTS. In Hardware and PCB design I have good experience in Arduino and IDF Espressif systems, based on ESP32, ESP32s2 and ESP32s3 chips with standard thermal cameras and ESP32 Drones, using MQTT messaging and SSL certificates (WiFi, Bluetooth and external sensors). I can design and build a custom PCB board. I like to choose projects that interest me and that match my skills and give me a challenge or bring something new.

Most game projects don't fail because of missing features. They fail because the systems underneath weren't built to scale. I build the systems that hold. I'm Technical Director at Override Systems. I've led the architecture on shipped PC, console, and mobile titles — not just features, but the data flow, authority models, and structural decisions that determine whether a project survives production. What I Do Gameplay & Combat: combat flow, player mechanics, ability systems, interaction models Data-Oriented Architecture: custom ECS, UE5 Mass Entity, performance-critical pipelines Multiplayer & Networking: authoritative replication, GAS, Steam/Edgegap dedicated server backend AI Systems: behavior trees, decision logic, pathfinding, simulation Tooling: editor tooling, configuration systems, designer-facing pipelines Shipped Work Lead & Architect — Grow Empire: Rome (Unity, mobile, 10M+ players) Lead & Architect — Toxic Crusaders (Unity, PC/Console) Lead & Architect — Mythic Legions (Unity, PC) Built Clockwork — custom archetype-based ECS in C# for high-performance simulation How I Work Architecture first. I ask about data flow and authority before writing a line of code. I lead small focused teams, write the hard systems myself, and flag problems early. I don't hide complexity behind magic frameworks. If you have a multiplayer or systems-heavy project and need someone to own the technical direction — send me the scope.
