🇳🇮 Nicaraguan developer · 📍 Based in Tuxtla Gutiérrez, Mexico · 🌎 Open to remote opportunities
I'm a self-taught engineer who grew from building static pages to shipping complete products with authentication, data, security, testing, CI, and cross-platform delivery.
I work across the stack, but my favorite problems live where product thinking, backend engineering, and applied AI meet. I care about privacy, useful software, safe defaults, and owning the full path from an idea to something people can actually use.
current_focus: "Local-first AI, RAG, developer tools, full-stack products"
building: "TrinaxAI"
working_style: "Understand deeply · Build simply · Test the risky parts · Ship"
languages: "Spanish (native) · English (professional growth)"
TrinaxAI is an open-source, local-first AI assistant that keeps inference and user data on their own hardware by default. It combines a FastAPI backend, React/TypeScript PWA, developer CLI, and a RAG engine for private files and code.
- Hybrid vector + BM25 retrieval, reranking, cited answers, collections, and multi-pass research
- Sandboxed coding agent with workspace confinement and approvals for dangerous actions
- Scoped and revocable device pairing for private features across a local network
- Local memory, voice, vision, attachments, optional web search, and cross-device sync
- Installers and CI for Linux, macOS, and Windows, plus automated releases and CodeQL
- 90+ Python/frontend test files covering the agent, CLI, RAG, security, pairing, state, and services

2022 ── HTML, CSS, JavaScript fundamentals
2023 ── Learning by building small web experiences
2024 ── Python and deeper programming foundations
2025 ── Django applications, authentication, databases, and CS50W
2026 ── Production platforms, computer vision, secure systems, and TrinaxAI v1.0
The constant has been simple: every project should teach me something the previous one could not.
