  • Reco rewrote JSONata with AI in a day, saving $500K/year.
  • Used AI to implement a pure-Go version of JSONata (gnata) in 7 hours for $400 in tokens.
  • Previous setup involved costly RPC calls to Node.js processes, costing ~$300K/year in compute.
  • gnata features a two-tier evaluation architecture for fast and complex expressions.
  • Achieved a 1,000x speedup on common expressions by eliminating RPC overhead.
  • Rolled out gnata in shadow mode for a week to ensure correctness before full deployment.
  • Additional optimizations in the rule engine saved another $200K/year.
  • AI-assisted code review was used, refining the process for future AI-generated code.
  • gnata is available as an open-source library with full documentation and a WASM playground.
