I'm a Brazilian software engineer who loves designing and building clean, intuitive user experiences with React and TypeScript. Recently, I've become very interested in learning more about AI and building agents that make businesses more productive. I also enjoy creating side projects and turning them into real businesses.

I was one of the most active contributors to coder/coder (10k+ stars), with 1,000+ PRs merged.

• Add workspace timings
• Add notification UI components
• All my contributions to coder/coder

These helped me broaden my skills across AI, UX, and project execution:

• AI Agent Developer from Vanderbilt University
• Google Project Management from Google
• Google UX Design from Google

I love turning ideas into real products. Here are a couple that grew into actual businesses:

• PasseJá - An AI-powered study platform with over 15,000 users and an MRR of around $400 USD. Developed using Next.js, TypeScript, React, and the AI SDK, with PostgreSQL and Drizzle for data management, and hosted on Vercel.
• TweetPik - Built and grew TweetPik to over $6,000 MRR before selling it to TweetHunter for $100,000 after two years of operation. Developed the platform using React, Next.js, TypeScript, and FaunaDB. TweetPik was featured as the #2 Product of the Day on Product Hunt during its launch.
