About me

Hi, I'm Sergio Corral. The curiosity to understand how things work has always been with me. Today, I focus on building backend infrastructure for AI agents — systems that are reliable, observable, and production-ready.

My core stack is Python and FastAPI, deployed on AWS serverless infrastructure (Lambda, ECS, CDK, DynamoDB). I work on event-driven pipelines, LLM integrations, voice AI backends, and MCP tool servers. I also have a background in full-stack development with React, Node.js, and Docker.

Earlier in my career I worked on blockchain automation — bots interacting with smart contracts on Ethereum and Ronin — which gave me a solid foundation in async systems, API design, and production reliability.
