I'm a Full Stack Web Developer & AI Engineer with 10+ years of experience across frontend, backend, testing, and DevOps. I've shipped products for companies in the US, Europe, and Brazil, always balancing solid architecture with real‑world delivery.
On the backend, I design and build production GraphQL APIs and federated architectures with TypeScript and Node.js. I've engineered AI‑powered checkout systems for major US telecom partners using Apollo Federation and WunderGraph, handling 1,000+ transactions per day with CI‑enforced contracts and New Relic observability. I also contributed to a reusable AI agent skills repository that standardized workflow automations across multiple client integrations, reducing new project onboarding time by 40%.
On the frontend, I have deep experience building modern React and Next.js applications for e‑commerce, enterprise dashboards, and complex form workflows. I've led Core Web Vitals and SEO improvements, implemented WCAG 2.1 AA accessibility, and created reusable component systems using TypeScript, Storybook, Jest, and Playwright.
I also build agentic AI systems and tooling. Agenthood is my open‑source multi‑agent framework where a squad of specialized agents enforce engineering standards, review code and commits, manage multi‑tier memory, and run autonomously via a TypeScript CLI. The project includes a browser‑based Studio playground with SSE streaming, 6 providers, and server‑side rate limiting.
My best work happens where scalable GraphQL backends, high‑quality React frontends, and AI agents meet — designing contracts, building the systems behind them, and shaping the UX that teams and users actually rely on every day.
