Lead Data Engineer, Alert Pipeline · CryptoAlertAI
Former Etherscan engineer · Smart contract security · Last updated: 2026-06-03
David O'Connor engineers the alert delivery pipeline at CryptoAlertAI: the cron jobs that poll exchange APIs every 5 minutes, the Redis cache layer, and the Telegram push notification infrastructure. He spent four years at Etherscan working on the gas tracker and the verified-contract index, and has disclosed three CVEs in widely-used DeFi libraries. David validates that every alert latency claim on the site is measurable and that backtest data is reproducible from raw exchange API logs. He holds a B.Eng. in Computer Science from Trinity College Dublin. David holds no tokens beyond ETH for gas (disclosed quarterly) and accepts no audits-for-pay arrangements with projects covered.
