Summary
👤
Senior🎓
Top SchoolCésar Valadez is a founder and AI engineer with 11 years of hands-on experience building production-grade systems that scale, from real-time data pipelines at Zillow to automation platforms at PayPal. He leads ValkymIA, delivering pragmatic RAG pipelines, multi-agent workflows, CRM integrations and edge LLM deployments for SMEs, and built Sigrun — a reusable multi-agent RAG framework using LangGraph, pgvector and Ollama. Equally comfortable in data and application engineering, he has reduced latencies, cut legal review cycles by 90%, and shipped multi-tenant field platforms supporting thousands of concurrent users. Self-taught by choice, César combines deep full-stack fluency (React, Node, Spring Boot, FastAPI) with modern AI stacks (pgvector, Ollama, Claude API), favoring solutions designed for real business constraints rather than demos. Open to senior AI engineering or AI-focused full-stack roles, he is based in Mexico City and available for remote or hybrid work.
