David O'Connor owns calculator accuracy and security at CryptoInfo365. Every formula, every API call, every JavaScript handler ships only after his review. David spent four years as a backend engineer at Etherscan, where he worked on the gas tracker, the verified-contract index, and the transaction simulation engine. He has identified and disclosed three vulnerabilities in widely-used DeFi calculator libraries (CVE-2023-XXXX, CVE-2024-XXXX, CVE-2024-XXXX — full details on his GitHub). David validates that every API call from a CryptoInfo365 calculator originates from the user's browser (we never log or proxy) and that no calculator stores PII. He holds a B.Eng. in Computer Science from Trinity College Dublin and reads English, Irish, and basic German. David holds no tokens beyond ETH for gas — disclosed on his profile. He accepts no audits-for-pay arrangements with projects covered editorially. Contact: [email protected] for technical bug reports or security disclosure.
