Currently exploring Agentic Workflows & AI Systems

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.

NestJS · PostgreSQL · ethers.js · Bull · AWS S3

Oak Protocol

The crowdfunding blockchain protocol itself — smart contracts audited by OpenZeppelin, Payment SDK and Contracts SDK powering Catarse, Vaki, and Rakunuew across LatAm.

Celo · Solidity · ethers.js · Privy · TypeScript

AWS Cloud Infrastructure

Production-grade AWS platform — EKS + ECS clusters, CloudFront CDN, VPC networking, S3 pipelines, and full GitOps CI/CD via Terraform and GitHub Actions.

Precisely engineered for
every layer

Backend

  • NestJS & Express
  • TypeScript & Node.js
  • PostgreSQL & Redis
  • BullMQ & REST APIs

Cloud & DevOps

  • AWS (EKS, ECS, S3, CloudFront)
  • Terraform & Docker
  • GitHub Actions & GitOps
  • Supabase & DynamoDB

AI & Web3

  • LangGraph & Claude API
  • Multi-agent orchestration
  • Solidity & ethers.js
  • Celo & Polygon

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.
