I will build a reliable backend for your crypto or web3 app
Backend Engineer: Payment Systems, Real Time Pipelines, APIs
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.
