Building what users
never see, but always feel
I began in the backend — REST APIs that handle millions of requests, databases that never sleep, server architecture that has to be right the first time.
As Lead Backend Engineer at Oak Network — the blockchain crowdfunding protocol backed by Kickstarter and a16z — I built the infrastructure powering Catarse, Vaki, and Rakunuew across Brazil and Latin America. Smart contract treasuries on Celo, PIX payment pipelines, and a production API serving over 2 million users.
From backend to
every layer of the stack
DevOps followed — Terraform modules, EKS clusters, ECS Fargate pipelines, and GitHub Actions across multi-environment AWS deployments. Then AI: multi-agent orchestration, LangGraph pipelines, and systems that don't just respond — they plan and act.
Catarse
Brazil's largest crowdfunding platform. Led backend — NestJS API, PIX payments via PagarMe, on-chain campaign treasuries on Celo, 2M+ users.

Case Studies
Production work across crowdfunding infrastructure, cloud platforms, agentic AI, and full-stack products — built at Oak Network and beyond, serving real users at scale.
Oak Autopilot — Multi-Agent AI Platform That Writes SDK Integrations
10 specialized agents across two LangGraph pipelines. Reduces SDK integration from days to ~14 seconds — codebase analysis, code generation, review, and PR creation, fully automated.

The frontier is
agentic AI
Systems that don't just respond — they plan, reason, and act autonomously. Multi-agent orchestration. LLM pipelines that do real work. Intelligent backends that think.
Like this fox crossing the terrain — always moving, always exploring what lies beyond the next ridge.
