About this Gig

Building a crypto or Web3 product and need a backend that won't lose or miscount anything? I build the server side: APIs, balances, rewards and access rules that stay correct under real traffic.

With 4+ years in production and hands-on crypto/Web3 experience, I've built ledger-based audit systems, reward and metering logic, and transaction tracking. I've also run real-time ingestion at ~1,000 events/sec, with peaks up to ~100,000/sec.


What you get:

  • APIs for your app, wallet-aware where you need it
  • Ledger and audit trail for every balance change
  • Rewards, points or usage-metering logic
  • Roles and access rules
  • Live updates and webhooks for your frontend
  • Clear docs and a handover call


Stack: I mostly work in TypeScript and Node.js, and can also match your existing stack.
