Juan Esteban Patiño — Full-Stack Developer & AI Product Builder

Juan Esteban Patiño

Full-Stack Developer | AI Product Builder | Colombia

React Next.js TypeScript Python FastAPI Go Node.js PostgreSQL Docker AI Agents

I build complete products end-to-end — from AI agents and logistics platforms to e-commerce stores and healthcare tools. I take ideas from zero to production, combining modern frontend interfaces, robust backend architectures, and intelligent systems powered by LLMs.

My engineering stack is built for real-world scale and delivery. I work with React, Next.js, Vue, and TypeScript on the frontend, FastAPI, Go, Node.js on the backend, and LangChain, OpenAI, and n8n to ship intelligent agents and automation workflows that solve actual business problems.

I design data layers using PostgreSQL, MySQL, Supabase, and ChromaDB, choosing the right tool based on structure, scale, and intelligence requirements. I integrate RAG pipelines, voice agents, and multi-tenant SaaS architectures — packaging everything with Docker and structured CI/CD for consistent, reliable deployments.

This profile reflects my approach to software: build products that work in production, not just in demos. Clean interfaces backed by powerful logic, intelligent pipelines, and a relentless focus on shipping things that matter.

What I Build

  • Full-stack products with React, Next.js, Vue, TypeScript, FastAPI, Go, and Node.js.
    • AI agents and RAG pipelines with LangChain, OpenAI, ChromaDB, and n8n automation.

      • Multi-tenant SaaS platforms with async microservices, RabbitMQ, and Go API gateways.

        • Production-grade deployments containerized with Docker and backed by PostgreSQL and Supabase.
