Let's start the technical round. Could you implement a Rate Limiter architecture in Node.js using Redis?

rate_limiter.js
async function checkLimit(req) {
  const key = `rate:${req.ip}`;
  // Token bucket logic
  return await redis.eval(...);
}
verified Evaluation

Time Complexity: O(1). Perfect! The Token Bucket algorithm correctly handles burst traffic. Your communication was also confident. Next question...
