Nicolás Ludueña

I build infrastructure and tools for technically difficult systems.

I'm a senior full-stack engineer at TxPipe, working across blockchain infrastructure, developer tooling, and privacy-preserving applications. I care about protocol correctness, maintainable systems, and tools that make complex workflows easier to operate.

Selected projects

  • WitnessFitness — a second-place 2026 Midnight hackathon project for privacy-preserving fitness challenges: prove the workout, hide the health data.
  • envbro — a Rust CLI for local and peer-to-peer .env management, powered by Iroh.
  • BigRational — arbitrary-precision rational arithmetic for TypeScript.
  • Midnight asset tokenization — a second-place 2025 hackathon project for private real-world asset ownership and trading.
