@sergio4brandon

I build AI agents, APIs, and full-stack products for business workflows.

What I'm looking for

I'm looking to build reliable AI-powered products end-to-end, turning complex business workflows into APIs, automations, and data pipelines. I value fast-moving teams, quality software, stability, performance, and practical LLM applications.

I've built AI-powered products at Blau Corp, Platzi, Agora Partnerships, and Geek Studio, turning business workflows into APIs, automations, data pipelines, and web and mobile applications. At Agora Partnerships, I built Necta, a LangChain-based agent that executes sales, registers inventory movements, and answers natural-language questions about business KPIs.

Across Python, Node.js, TypeScript, React, Flutter, and AWS, I own systems from backend services and LLM integrations to mobile features, CI/CD, and observability. I've delivered more than 30 APIs, reduced report generation from one month to seconds, and implemented production RAG, embeddings, tool calling, and AI evaluation workflows.
