SOFTWARE ENGINEER
Cesar Goncalves
Building backend systems and AI tools that actually solve problems. Python, TypeScript, and a hospitality-trained eye for what users really need.
About Me
I build APIs and systems that are reliable and maintainable. Coming from hospitality, I learned that good communication beats perfect code.
I'm a backend engineer focused on AI applications, LLMs, and agent workflows. Currently building MCP servers that connect AI to business systems—enabling intelligent automation that teams can actually understand and maintain.
My toolkit spans Python and TypeScript, with experience in FastAPI, LangGraph, RAG systems, and the full DevOps stack—Docker, Kubernetes, CI/CD, and cloud deployments on AWS and GCP.
I hold a First-Class Honours degree in Computer Science from Birkbeck, University of London. If you're working on something interesting in AI or backend architecture, let's connect.
