I build the systems your business can't afford to get wrong.
18 years shipping production infrastructure across fintech, crypto, and enterprise. From React frontends to Rust backends, Solidity smart contracts to D3 visualization platforms. One person, zero handoff delays, full ownership from architecture to deployment.

What I Build
Complex System Architecture
Matching engines, trading platforms, real-time data pipelines, message queue systems. The kind of infrastructure where a bug costs real money.
Blockchain & Cryptography
ZK-SNARK circuits, smart contracts on Ethereum and Solana, cross-chain protocol layers, Rust-to-WASM pipelines. Privacy-preserving systems that actually ship.
Frontend at Scale
Micro frontend migrations, 60fps trading UIs, D3 visualization platforms, PWAs with offline capability. For teams that have outgrown their monolith.
How I Work
Roles
Technical Lead, Senior IC, Staff Engineer, Frontend/Backend Architect. I am comfortable leading teams or going deep as an individual contributor.
Engagement
Contract (3–12 months) or full-time. I take on 1–2 engagements at a time to give each one full attention.
Stack
React, Next.js, TypeScript, Node.js, NestJS, Rust, WebAssembly, Solidity, PostgreSQL, MongoDB, Redis, Docker, AWS, GCP. I pick the right tool for the job, not the one I used last.
Timezone
Based in Brazil (UTC−3). Full overlap with US East Coast. 4–5 hours overlap with Western Europe. Async-first by default.
By the Numbers
Hard problems don't get easier with time. They get more expensive.
Tell me what you are building and what is blocking you. I will tell you honestly whether I am the right person for it.
