About Me
Building with AI as my teammate
I wrote my first line of code in 2010, in C. Today I work mostly with TypeScript, React, Next.js, Tailwind CSS, and shadcn/ui. I use Cursor, Zed, and CLI agents as an integral part of my workflow, maintaining architectural oversight while shipping faster.
I worked at Google for 4.5 years before leaving to build my own products. Now I operate as an Indie Founder, orchestrating an AI-assisted workflow: I plan the architecture, the AI drafts the implementation, and I review and refine. System design and code quality remain my responsibility.

Portfolio
Selected Works
Building developer tools, AI-native applications, and products.
Acerto AI
Automated B2B System
An automated collection and notification system. Built the MVP to validate the idea quickly and solve a concrete business problem without writing unnecessary custom code.
Why it matters: Event-driven workflows solving real business needs.
Override.sh
Browser Extension & AI
A browser extension for custom CSS/JS modifications. Gives the AI direct access to the DOM to write and apply visual or functional patches on the fly.
Why it matters: It is fun! And bridges the gap between browser extensions and LLMs.
GhostKeys
AutoHotkey v2 & Rust
A system-wide keyboard remapping utility simplifies typing Brazilian Portuguese and English on a physical US-layout keyboard. Built leveraging a 4-step AI workflow to deploy complex system logic in languages I had zero prior experience with.
Why it matters: Proving that strong fundamentals translate across any syntax.
Self-Hosted Infrastructure
VPS & Orchestration
Configured and managed a custom VPS using Coolify and Docker. Currently hosting my LLM router (LiteLLM) and automation pipelines.
Why it matters: Hands-on experience in server management outside of PaaS.
Concept Compass
AI Mind-Mapping
An infinite mind-map generator using OpenAI's OSS models. Built specifically to test and learn Kiro, an AI-powered, spec-driven coding assistant. My first contact with OpenRouter, now an essential tool for my AI workflows.
Why it matters: Deep-diving into AI integrations and routing models.
DevMagic
DevContainer Configuration
A devcontainer setup that "just works". Built in public to help developers avoid configuring the same environment settings over and over again.
Why it matters: Solving the "works on my machine" problem.
Adapta AI Challenge
🏆 Top 3 / 2,000+ applicants
OOH analytics tool built in ~24 hours for Brazil's largest AI hackathon. Presented to ~7,000 people at the Adapta Summit main stage.
Why it matters: High-pressure, high-visibility delivery. Selected from ~80 finalists (2,000+ applicants).
Viralei
AI Video and Content Generation · Top 9 / 36
Turns legislative bills into engaging TikTok-like videos using AI. Built and deployed the MVP in 4 days with Next.js.
Why it matters: Demonstrates high velocity and product sense.
VSCode Improved
Extension Bundle & DX Tools
A VS Code extension bundling quality-of-life improvements. Built to improve my own workflow.
Why it matters: Hands-on experience with the VS Code Extensions API.
