Optimized third-party API, DB, and blocking calls, achieving ~45% reduction in platform thread usage, ~35% memory savings, and ~1.5x throughput. Built a secure logging framework with dynamic regex and JSON key-based masking to enforce PII protection. Built an automated code generation algorithm with ~90% mapping accuracy, reducing microservice setup time from ~3 hours to 20 minutes.  Upgraded the bulk code generation platform to support parallel generation of multiple microservices, improving delivery speed by over 60%. Executed performance and load testing using JMeter and service profiling using VisualVM. Implemented authentication and authorization mechanisms including JWT, role-based access, and protected endpoints.
