Daniel Neris

Senior Backend Engineer 路 Node.js, TypeScript 路 Distributed Systems & P2P 路 Fintech & Web3

I build production backends in Node.js and TypeScript for fintech, banking and Web3. I co-founded Zuvia, the platform behind Brazil's first real estate tokenization on B3 infrastructure, with R$300M+ in transaction volume and 8,000+ investors. Now I'm focused on privacy-first, decentralized, peer-to-peer software on the Holepunch/Pear stack.

Open source

  • retry: asynchronous interviews that run peer-to-peer on Pear. Blind-pairing invites, one Hyperdrive per side, on-device transcription and answer review. No server, no API calls.
  • udp-from-scratch: reliable transport over raw UDP in Node.js with zero dependencies. Binary wire format, acknowledgements, retransmission and an anti-spoofing handshake.
  • event-driven-ecommerce-system: NestJS microservices over Kafka with a transactional outbox, saga with compensation, Redis distributed locks, dead-letter queues and a CQRS read model.
