Parth Negi

@parthnegi

Senior Java Backend Engineer at Capgemini who cut API response times from ~20 seconds to under 1 second and built secure microservices.

At Capgemini Technology Services, I architected a System-of-Record microservice that automated validation, deduplication, and policy-driven purging of member records. I also brought API response times from ~20 seconds to under 1 second through in-memory caching and asynchronous workflows.

I built secure microservices for regulated PII integrations and an MCP/REST adapter for an internal Claude-powered defect triage agent. Earlier at Capgemini, I migrated enterprise microservices from Java 8 to 11 and developed Spring Boot APIs, Kafka messaging, and automated tests.
