Professional Summary
Software engineer with more than 8 years of self-taught and professional experience developing complete technology solutions, covering mobile and web applications, game engines, programming languages, interpreters, compilers, generative AI systems, and enterprise SaaS platforms.
Founder of Gitbon Labs, a technology holding company from which I lead product development across two main divisions: GitbonTech (enterprise software, SaaS platforms, and traceability solutions with RFID and AI) and GitbonGames (2D/3D video games, generative AI integration, and custom graphics engines).
I have built projects that demonstrate exceptional command of C++ and C#, software architecture, compilers, tree-walking interpreters, 2D graphics engines built from scratch, generative AI API integration (Google Gemini) in Unreal Engine 5, and multi-tenant architecture for SaaS systems.
I have competed in international hackathons with more than 35,000 participants, and my projects have received national recognition for their social and technological impact. My deliverables are characterized by zero critical post-launch defects and 100% client satisfaction on completed projects.
My approach is based on a structured, phase-based methodology: detailed BRIEFs for each phase (with scope, objectives, deliverables, and risks), implementation reports with tables, diagrams, and metrics, thorough QA (smoke tests, unit testing, and client acceptance), and complete final documentation including technical manuals, user guides, and architecture diagrams. I also offer one month of free post-delivery support, ensuring stability and client satisfaction.
Career goal
I am looking for opportunities to apply my technical vision in high-level professional environments, preferably in the video game industry, enterprise software, and AI integration, where I can add value from day one and continue growing as a systems engineer.

Professional Experience
Gitbon Labs — Founder and Lead Developer
End-to-end leadership and development of technology products under the GitbonTech (enterprise software) and GitbonGames (video games) divisions. Responsible for the architecture, implementation, testing, documentation, and product strategy of each project.
Key achievements:
- GSH (Game System Hub): Complete 2D engine and custom scripting language (.gsh), built from scratch in C++20 with Raylib 5.0. Lexer, parser, AST, tree-walking interpreter, actor system, AABB physics, 2D camera, audio management, layer system (Z-index), lazy loading of assets, embedded IDE with a runtime viewport, and a sandbox for hot-reloading code. Stable 60 FPS on low-end hardware; 40% faster asset load time through lazy loading. Playable demos: Breakout, arena shooter with AI pursuit, platformer, and space combat.
- Logic Breach: Investigation and interrogation game in Unreal Engine 5 with a 1947 noir aesthetic, integrating the Google Gemini API to generate dynamic, adaptive dialogue in real time. AI interaction systems, character states, asynchronous communication with external APIs, contradiction detection (95% effectiveness), and C++/Blueprint synchronization. Gemini 3 Hackathon (Google / Devpost), 35,535+ participants worldwide.
- Batalla Espacial Ultra: 2D action game for Android built in Godot with GDScript. Wave system, 5 enemy types, Power-Up system, final boss, progressive difficulty, lives, scoring, High Score, and coins. Stable 60 FPS on 90% of low-end devices.
