How often have you proposed or implemented new ideas in the project?

In Node.js projects, I regularly proposed and implemented new ideas, such as performance optimization through the use of asynchronous functions and promises, implementing caching to reduce database load, as well as improving code structure through modularity and adopting TypeScript for increased reliability. The frequency of such proposals depended on the project stage, but it usually happened when identifying bottlenecks or planning new features — approximately every few weeks.

Example of implementing caching using Redis:

const redis = require('redis');
const client = redis.createClient();

async function getUser(id) {
  const cacheKey = `user:${id}`;
  const cached = await client.get(cacheKey);
  if (cached) {
    return JSON.parse(cached);
  }
  const user = await db.query('SELECT * FROM users WHERE id = ?', [id]);
  await client.set(cacheKey, JSON.stringify(user), 'EX', 3600); // cache for an hour
  return user;
}
