Here is a little background

Hey 👋 I am a Senior AI & Data Engineer currently based in Ciudad Guzmán, Jalisco, Mexico. I am obsessed with building production-grade AI systems that solve hard problems.

I don't just write scripts; I architect Autonomous Agents, RAG pipelines, and follow the lifecycle of Classical ML models and Fine-tuned LLMs that drive real automation. Currently at EY, I’m pushing the boundaries of enterprise data systems by replacing legacy heuristics with predictive models and Semantic Reasoning.

I am looking for a challenging technical role where I can deploy complex AI architectures, from training custom models to orchestrating multi-agent workflows, rather than just maintaining data pipelines.
