API Optimization & get JSON values for variance data

My current working API system is experiencing slow response times, particularly during data processing within the API. While I'm not certain about the specifics of the data processing tasks causing the delays, there's a need to improve the efficiency of the system. I also require that variance data is pulled and displayed correctly in drop down boxes.

Key Responsibilities:

- Identify bottlenecks in the current API system and implement improvements

- Ensure the API pulls results faster

- Utilize JSON values for variance data
