Have you had experience expanding and optimizing infrastructure or systems for load growth?

Yes, I have experience in expanding and optimizing infrastructure to handle increased load.

The main steps included:

• Analyzing bottlenecks using monitoring and profiling.
• Optimizing code and database queries to reduce response times.
• Implementing caching (e.g., Redis) to reduce database load.
• Horizontal scaling (adding servers) and vertical scaling (increasing resources).
• Using load balancers to distribute traffic evenly.
• Automating deployment and monitoring for quick response to changes.

Example: As the number of users increased, the API started responding slowly. After analysis, we identified slow database queries, optimized indexes, added caching, and configured horizontal server scaling, which allowed handling increased load without performance degradation.
