Senior Frontend & Full Stack Engineer
Building products with TypeScript, React, Next.js, and Node.
Senior engineer with 5+ years shipping production web and mobile apps for teams across Brazil, the US, and globally. I focus on the spot where polished frontend craft meets pragmatic full-stack delivery — React/Next.js on top, NestJS/Node and Postgres underneath, and increasingly AI APIs in between. Comfortable owning features end-to-end, from product discovery to telemetry.
- 🛠 Senior Frontend @ Arena.im / MyAvatar.ai — frontend for an AI first Avatar platform and building widgets that ship inside ESPN, Reuters, and Fox Sports.
- 📡 Wiring product telemetry with RudderStack + Datadog + Intercom to turn user behavior into roadmap decisions.
- 🤖 Daily driver for Claude Code as a pair-programming agent — planning, refactors, code review, and one-shot scripts straight from the terminal.

AI — building with & building alongside
Tooling & Infra
I treat AI as a teammate, not a magic wand. Day-to-day that means:
- Claude Code in the terminal for planning, refactors across large diffs, generating tests, and reviewing PRs before I ship them.
- Building with LLM APIs in production — Gemini for video/avatar generation and ElevenLabs for voice cloning at Arena.im / MyAvatar.ai, with the Vercel AI SDK for streaming UI.
- Custom agents & slash commands scoped to repo conventions, so the model follows the codebase's rules instead of inventing its own.
- MCP servers to give agents access to project context, design files, and internal data sources.
