Acerca de Gabriel
With 6+ years as a Data Engineer/Analytics Engineer, I've designed scalable pipelines using Python, Spark, and Databricks, migrating legacy SQL/SAS architectures into modern, cost-efficient systems that cut manual reporting from hours to minutes. Now I'm applying that same foundation to AI engineering: building multi-agent pipelines with Python, FastAPI, PostgreSQL, and OpenAI/Anthropic APIs that let teams query and analyze their data through natural conversation, no SQL required. I sit at the intersection of data and AI: strong enough in pipelines and architecture to build reliable systems, and hands-on with LLM-powered tools to make those systems intelligent and self-service. If you need someone to design a data pipeline, modernize a legacy system, or build an AI agent that turns your data into answers, I can bring both sides together.
