# Davi Reis Vieira

> Davi Reis Vieira — founding team, tech at Refer. Programming since 11, when Counter-Strike mods turned into a career. Computer Engineer (Insper), AWS CTO Fellow, Fundação Estudar Tech Fellow. This is his personal site — an interactive desktop OS (DaviOS) with the same content available as a plain page and as Markdown.

In his own words: I started programming at 11 because I was bad at Counter-Strike. Instead of practicing, I wanted to know what was going on behind the game — and whether I could change it. That curiosity turned into reverse engineering, bug bounties, GTA roleplay servers and Flight Simulator add-ons I sold as a teenager, and it is still how I work: open the thing up, understand it, make it do something new. Today I'm on the founding team at Refer, building the technology that matches exceptional engineers with the AI companies shaping what comes next.

## Profile

- [About Davi Reis Vieira](https://davireis.com/about): The whole profile on one readable page — story, experience, projects, education, certifications, awards and contact.
- [Full profile in Markdown](https://davireis.com/llms-full.txt): The same profile as a single Markdown file, convenient for LLM context.

## Projects

- [StackPort](https://stackport.cloud/): See everything running in your AWS emulator. An open-source browser for AWS resources across 35 services, working against LocalStack, MiniStack, Moto, or a real AWS account through one interface. Read and write — browse S3, invoke Lambdas, push SQS messages — with live updates over WebSockets, a CLI for CI pipelines, and guided lessons that run against your own emulator.
- [StackPort — GitHub](https://github.com/DaviReisVieira/stackport)
- [MD Formatter](https://davireis.com/md-formatter): Readable Markdown and llms.txt, the moment you open them. A browser extension that notices when a page is a Markdown document and renders it in place — the way a JSON formatter handles raw JSON. Built for the llms.txt era: an index renders as browsable link cards rather than a wall of bullets. No configuration, no tracking, and no network requests of its own.
- [MD Formatter — Add to Chrome](https://chromewebstore.google.com/detail/jhikgiggooiokohjghdcojppgpildepg)
- [MD Formatter privacy policy](https://davireis.com/md-formatter/privacy): What the extension does and doesn't do with your data.
