Carlos Galarza
Working on Executable Rationality and efficient AI.
I learn, research, experiment, and build things I find useful. Mostly AI these days. Agents, computer use, applied research. Right now I'm mostly building Sevra, a shared brain for AI agents.
Say hiplaying with
Sevra
A shared brain for AI agents. Company knowledge as plain files that agents read, update, and work across. Home of the db.md open standard.
VibeCraft
A complete computer for AI agents — dedicated machines where agents used real browsers, terminals, and filesystems. Building it taught me the brain was the product, not the machine. Became Sevra.
Math a Server Can't See
Encrypt two numbers in your browser, watch a server compute on them without ever seeing them, then decrypt the answer. Real fully homomorphic encryption with live metrics, and the privacy boundary drawn on screen.
Zero to GPT-2
An interactive walkthrough of GPT-2 from first principles. Built so I could finally understand transformers properly.
The Essence of GraphRAG
A visual, interactive walkthrough of the core idea behind GraphRAG and why it works differently.
Aven
Claude Computer Use as a desktop app. Built with Tauri and the Vercel AI SDK.
AI Therapist (ASMR)
An AI therapist with a whispering voice. A demo using the OpenAI Realtime API, ElevenLabs, and Fal.ai.
Make Your Own JS Runtime
How to build a JavaScript runtime on top of Deno Core and Rust.
Tauri + Deno PoC
Running multiple Deno tasks safely inside a Tauri app. Permissions, IO, and lifecycle.
CodePortal
An earlier platform for building apps with natural language. Predates a lot of what's happening now.
Figma app for Linux
Unofficial Figma desktop app for Linux, with local font support. Built it because I needed it.
Blocklify
JavaScript to Blockly blocks. Parses code and imports it into the visual block editor.
work with me
Most of my week goes into building Sevra. One or two days go to companies shipping AI agents to production, where I work as an embedded AI lead. I take one, maybe two clients at a time, and right now there's room for one more.
professional work
A few of the people and places along the way.
Will McLellarn
Founder, General Dev · Stanford alum
“Stop considering and work with Carlos. He’s been an incredible asset to my business, clear on strategy, excellent communicator, and the rare kind of builder who can actually ship. He led, contributed, and taught along the way, and brought real passion to every project.”
Naveed Hedayati
Head of Product, Co-Intelligence Labs
“Highly recommend Carlos – he helped unblock me and gave me a path forward in my MVP with Bolt, and then he even provided suggestions for ways to streamline the process as I moved forward.”
Randall Reilly
Trucking & Logistics
Years of trucking-industry hiring data spread across three dashboards. Clients needed training to run even basic queries. Most of the data went unused.
I built a chat interface that unified all three systems. Ask about hiring costs in Texas and you get the number, how it compares to neighboring states, and whether it’s trending up or down.
