Become a sponsor to Fabio Ritzel Borges

Hi, I'm Fábio Ritzel Borges (Fabinho)

I'm a Senior Full-Stack & AI Engineer from Joinville, Brazil, with more than 10 years of experience building scalable web systems. I care about clean code, strong performance, accessibility, and architectures that age well.

What I Do

• Backend & APIs: production GraphQL services and federated architectures with TypeScript and Node.js (Apollo Federation, WunderGraph) for US and European companies.
• Frontend: modern React and Next.js applications, WCAG 2.1 AA accessibility, reusable component systems, and Core Web Vitals optimization.
• AI & Agents: agentic AI systems and tooling — multi-agent frameworks, RAG pipelines, and LLM-powered products with the same discipline I apply to production web systems.

Featured Open Source Work

• agenthood — a society of 18 specialized AI agents with impeccable standards. Enforces engineering standards, reviews code and commits, manages multi-tier memory, and runs autonomously via a TypeScript CLI. Ships as an npm package, a VS Code extension, and an Academy. Live at agenthood.flabs.tech.
• agenthood-site — the Agenthood marketing site, including the Studio chat playground with SSE streaming, 6-provider routing, BYOK, and a runtime dashboard.

Why Sponsor Me?

Your sponsorship gives me time and focus to keep creating and maintaining open-source tools that I believe are genuinely useful. It helps me:

• Maintain agenthood and agenthood-site — fixing bugs, shipping releases, writing docs, and answering issues so the tools stay reliable for everyone using them.
• Cover infrastructure costs — hosting the Studio playground, vector databases, and API usage that keep the live demos running for free.
• Build new features and open-source projects — from AI agent tooling to portfolio and dev-tooling experiments.

If my work has helped you in your own projects or sparked ideas you've used, I'd be grateful for your support.

Thank you for being part of the open-source journey.
