I build Python backends, AI integrations, and game engine tooling in Godot 4.
I work as a developer at a government institution in Argentina. I led the migration of a production system from Java 5 to Django and Svelte. I work with a fragmented stack every day — Java, Django, Node, Laravel — so I know how to ship changes without breaking legacy code.
I'm open to freelance work in:
- RAG pipelines and LLM agent systems (Python)
- Backend development (Django, FastAPI, Node.js)
- Legacy migration and modernization
- Godot 4 tooling and GDScript
| Area | Tools |
|---|---|
| Backend | Python, Django, FastAPI, Node.js, REST |
| AI / LLM | OpenAI, Anthropic, Gemini, RAG, embeddings, multi-LLM agents |
| Data | PostgreSQL, pgvector, Redis |
| Architecture | Event-driven, microservices, outbox pattern, NATS JetStream |
| Infra / Obs. | Docker, Prometheus, Grafana, Loki, cAdvisor, Nginx |
| Game Dev | Godot 4.6, GDScript, hex grids, pathfinding, fog of war, combat engines |
Hexagonal grid toolkit for Godot 4.6+. Coordinates (offset + cube), pathfinding (Dijkstra + A*), 3-state fog of war with line-of-sight, batch rendering for large maps, and camera controls.
The simulation layer is render-agnostic and deterministic — logic runs on coordinates and data with no hidden randomness. Suitable for play-by-email, lockstep multiplayer, headless servers, replays, and AI/ML training.
Free MIT version + paid Pro version with extra features. Published on itch.io and the Godot Asset Library. Active sales.
A headless, domain-agnostic card combat engine for Godot 4.6 / GDScript. Handles turn FSM, mana, draw, attack/block, damage resolution, and pluggable AI. Fully deterministic for a fixed seed — reproducible bit-for-bit, ideal for replays and server-authoritative netcode.
Inject your game rules via Callables. The engine knows nothing about
your GDD, rarities, or loaders. CI-tested. Published on the Godot Asset
Library.
A custom agent harness with judge systems across Anthropic, Google, OpenAI, and Kimi. Embedding storage and automatic context compaction. Built from scratch — no LangChain, no framework lock-in.
Event-driven system for trading card game libraries. Microservices with NATS JetStream, PostgreSQL + pgvector for hybrid vector search, and full observability (Prometheus, Grafana, Loki). Five services complete and running.
