## The Problem
Static CVs don't show what you can actually build. A PDF lists skills — it doesn't prove them.
## The Solution
A production-grade interactive portfolio that **demonstrates the skills it describes**: dual-mode AI chatbot (text + voice) with agentic RAG, full LLMOps observability with custom dashboard, 71 automated evals as CI gate, prompt versioning, and a closed-loop that generates tests from production failures.
**Key Features:**
- **AI Chatbot "Santi"** — Text (Claude Sonnet) + Voice (OpenAI Realtime API). Responds in first person as Santiago. Agentic RAG with hybrid search (pgvector + BM25) and Haiku reranking
- **6-Layer Defense** — Keyword detection, canary tokens, fingerprinting, anti-extraction, online safety scoring, adversarial red team. Real-time jailbreak email alerts
- **71 Automated Evals** — 10 categories: factual accuracy, persona, boundaries, quality, safety, language, RAG quality, multi-turn, source badges, voice quality. CI gate on every push
- **LLMOps Dashboard** — Private `/ops` with 8 tabs: Overview, Conversations, Costs, RAG, Security, Evals, Voice, System. Real data from Langfuse + Supabase
- **Closed Loop** — Trace → online scoring → quality < 0.7 → auto-generate test → CI gate blocks deploy
- **Voice Mode** — OpenAI Realtime API, audio-to-audio, shared RAG pipeline, ~$0.25/session
- **6 Published Case Studies** — Bilingual (ES/EN) with JSON-LD, prerendered HTML, cross-linked RAG, and interactive architecture diagrams
- **Interactive Architecture Diagram** — GSAP-animated SVG with narrated audio, pan/zoom, dark mode sync. [Explore it →](https://santifer.io/self-healing-chatbot#architecture)
- **GEO-ready** — `llms.txt`, structured data (JSON-LD), AI crawler-friendly robots.txt

> Portfolio interactivo con chatbot IA (texto + voz), RAG agéntico, 71 evals automatizados, dashboard LLMOps y defensa anti-inyección en 6 capas
[](https://santifer.io)

## El Problema
Los CVs estáticos no demuestran lo que realmente sabes construir. Un PDF lista habilidades — no las prueba.
## La Solución
Un portfolio interactivo de nivel producción que **demuestra las habilidades que describe**: chatbot IA dual (texto + voz) con RAG agéntico, observabilidad LLMOps completa con dashboard custom, 71 evals automatizados como CI gate, versionado de prompts, y un closed-loop que genera tests de fallos en producción.
**Funcionalidades:**
- **Chatbot IA "Santi"** — Texto (Claude Sonnet) + Voz (OpenAI Realtime API). Responde en primera persona como Santiago. RAG agéntico con búsqueda híbrida (pgvector + BM25) y reranking con Haiku
- **Defensa en 6 capas** — Keyword detection, canary tokens, fingerprinting, anti-extraction, online safety scoring, adversarial red team. Alertas de jailbreak por email en tiempo real
- **71 Evals automatizados** — 10 categorías: factual, persona, boundaries, quality, safety, language, RAG, multi-turn, source badges, voice. CI gate en cada push
- **Dashboard LLMOps** — `/ops` privado con 8 pestañas: Overview, Conversations, Costs, RAG, Security, Evals, Voice, System. Datos reales de Langfuse + Supabase
- **Closed Loop** — Traza → scoring online → quality < 0.7 → auto-genera test → CI gate bloquea deploy
- **Modo voz** — OpenAI Realtime API, audio-to-audio, mismo pipeline RAG, ~$0.25/sesión
- **6 Case Studies publicados** — Bilingües (ES/EN) con JSON-LD, HTML prerenderizado, RAG cross-linked y diagramas de arquitectura interactivos
- **Diagrama de Arquitectura Interactivo** — SVG animado con GSAP, audio narrado, pan/zoom, sync dark mode. [Explorar →](https://santifer.io/chatbot-que-se-cura-solo#architecture)
- **GEO-ready** — `llms.txt`, datos estructurados (JSON-LD), robots.txt amigable con crawlers IA
