AI & Backend Engineer · Tech Lead — building AI agents, resilient backends, and the Python UI layer they were missing
Electrical Engineer with 20+ years in tech and Python since 2002. Currently leading the backend architecture of a health-insurance platform (NestJS, FastAPI, MongoDB, AWS) with real-time payment integrations across Venezuelan banks. Free Software advocate since the Debian Venezuela days ❄️ Arctic Code Vault Contributor.
- 🧩 Reflex AI toolkit — serving and operating AI agents in pure Python with Reflex:
- reflex-agentkit — AG-UI protocol client, streaming chat, tool-call cards and human-in-the-loop approval for LangGraph, PydanticAI and any AG-UI agent
- reflex-mcphost — an open MCP host: connect stdio / Streamable HTTP servers, browse tools, resources and prompts, render MCP Apps, with a consent layer
- reflex-agentlens — self-hosted agent observability from OpenTelemetry GenAI traces: run timelines, graph replay, token and cost analytics
- reflex-assistant-ui — port of assistant-ui (AI chat) to Reflex
- 📦 40+ Reflex custom components, 36 published on PyPI — React libraries wrapped as pure-Python components: dataviz (nivo, Perspective, rosencharts, monocharts, TanStack Charts, Chart.js), maps & 3D (MapLibre, Cesium/resium, react-globe.gl, map3d, Three.js), medical imaging (OHIF DICOM viewer, NiiVue, nnInteractive, ICD-11 ECT), editors & UI (React Flow, xterm.js, Mermaid, Schedule-X, Ant Design, React Bits, react-joyride, Pragmatic drag and drop) and more
- 🎨 Silverpoint — a charting library for React and Angular whose visual language is Renaissance drawing technique (silverpoint, hatching, hand-drawn marks), with its Reflex bindings and website
- 🤖 Prismal — open-source, security-first multi-agent orchestration framework built on LangGraph: central supervisor + specialist agents, reasoning patterns, RAG engines, provider-agnostic via LiteLLM, native MCP support — plus prismal-server (REST/WS/SSE), SDK, web chat, dashboard and TUI (evolution of the now-deprecated LightAgent)
- 🖥️ Umbral — a local-first agentic terminal written in Go
- 🌎 vigia-eew — cross-platform real-time earthquake early-warning agent (EMSC WebSocket + USGS FDSN fallback) with non-dismissable alerts on Linux, Windows & macOS
- 🐧 omagnome — opinionated, reversible, keyboard-first developer desktop for Ubuntu + GNOME (Omarchy's ideas, without leaving GNOME)
- 🧠 LangGraph agent architectures — tutorials and applied agents (recruitment analysis, MCP demos, data-analysis chatbots) with Reflex front-ends; teaching 16 agentic design patterns
- ⚡ Local LLM inference on AMD — ROCm, llama.cpp, and NPU (XDNA 2) benchmarking on Linux
- 53 new repositories created this year — 45 of them in Python
- 36 packages published on PyPI under seraph13
- 8 repositories in the prismal-ai organization (framework, server, SDK, web chat, dashboard, TUI, notebooks)
