I will audit up to 500 lines of Node.js or TypeScript code

Security-focused review of one public or sanitized Node.js/TypeScript component up to 500 lines. You receive: severity-ranked findings with file:line evidence; checks for injection, auth/authz, SSRF, secrets, unsafe parsing, race conditions and dependency risks; concrete fixes; patched snippets or a review-ready PR when agreed; focused regression tests; and one revision. Fixed price: 50 USD in USDT or USDC. Delivery: 24 hours after scope confirmation. No call or interview. Send a repository link or sanitized code with acceptance criteria.
