At MedImpact Healthcare, I led a team of 27+ engineers and architects delivering a multi-cloud healthcare platform on AWS and Azure. It achieved 99.99% uptime and 100% SOC2/GDPR compliance. I also modernised IBM BPM and Camunda into Kafka-driven Spring Boot microservices, achieving a 21% throughput gain and an 18% infrastructure cost reduction. A custom Java Zero Trust WAF with mTLS, OAuth2 and OWASP Top 10 mitigations reduced the attack surface by 80%. In my independent consulting work, I designed API and integration architectures and developed Agentic AI platforms using LangChain4j, RAG and GraphRAG. Spring WebFlux microservices with FAISS/OpenSearch reduced API latency by 40%, while Agentic AI with Istio cut production incidents by 35%. ``` ## Experience ### Senior Solution Architect Independent Consulting.
