About Nate Lemos
I'm Nate Lemos, an AI agent engineer in San Antonio, TX. At Silktide, I build production AI agents with LLMs, the Anthropic SDK, and MCP. Before that, I worked on Microsoft Azure and the Halo Infinite backend at 343 Industries. I also build my own AI tools and write about what I learn.
I've been writing software professionally since 2013. Started at a small company in Brazil doing C#, eventually moved to the US and worked at 343 Industries on the Halo Infinite backend, then spent about two and a half years at Microsoft on the Azure Portal team (IaaS Core — I owned the Disks blade, ~100k weekly users). Now I'm at Silktide, where I built the Studio Agent with LangChain DeepAgents, multi-provider LLM routing, and MCP tools, plus an SEO/AEO reporting pipeline.
I work primarily in TypeScript, but I've shipped production C#, React, .NET microservices, Kafka pipelines, and AWS/Azure infrastructure. I don't have a strong stack preference — I like building things that actually work.
Speaking: I'm giving a talk called “My wife is a vibe-coder. So, what now?” at LLMday in Austin, TX on Oct 14, 2026.
What people I've worked with say
“Natanael was definitely one of the best partners I ever had since college times. A decade ago was already one of the most talented programmers I ever met in a way that every team feel confident to solve any issue just for having him around. A good human being, friend and guitar player makes clear how committed he is to everything he does.”
“Natanael was the best scrum master I've ever met, as well as being an excellent developer on Microsoft technologies.”
“Natanael is a very creative guy. His ideas are helpful to solve a different kinds of problems in a easier way. Is really nice to develop programming projects with him.”
“Extremely competent and committed to his work. Besides being an excellent professional, an excellent person.”
