Key Achievements

Highlighting some of my most significant accomplishments in my career.

Optimized API Response Time for High-Traffic Services

Successfully optimized critical APIs used in a high-traffic project, reducing response times from 16–21 seconds to an average of 2.8 seconds.

  • Identified performance bottlenecks caused by internal microservices making API calls, sometimes within loops (e.g., fetching organizational names for data validation).
  • Implemented Redis caching to store and serve frequently accessed configuration data locally, reducing redundant API calls.
  • Developed a fallback mechanism: queries first check Redis and only call the API if data is unavailable in the cache.
  • Leveraged multi-CURL to parallelize requests, further enhancing efficiency.

This achievement demonstrates my expertise in performance optimization, microservices, and caching strategies to handle large-scale applications effectively.
