Terminal: crypto payment orchestrator

Create a reliable integration layer so the main product does not need to know the RPC specifics of every blockchain.

Responsibilities

• Generate user-linked deposit addresses on demand.
• Process node callbacks, transaction IDs and confirmation changes.
• Map wallet labels to users and persist transfer history.
• Synchronize exchange rates and deliver user and operator notifications.

Role: backend/fullstack developer — service architecture, RPC integrations, data model and background processing.

I built authenticated API endpoints, adapters for Bitcoin-family nodes, Ethereum and Monero experiments, queue jobs for balance updates, a confirmation-aware transfer flow and scheduled rate imports from CoinGecko and CryptoCompare. Separate database connections keep service data apart from the product ledger.
