Recent results:
- Reduced API latency 40% with Spring WebFlux microservices + vector databases(FAISS/OpenSearch)
- Cut production incidents 35% via self-healing Agentic AI integrated with Istio service mesh
- Delivered 99.99% uptime on a multi-cloud (AWS + Azure) healthcare platform with 100% SOC2/GDPR compliance
- Reduced attack surface 80% with a custom Java Zero Trust WAF (mTLS, OAuth2, OWASP Top 10)
- Transformed legacy IBM BPM into Kafka-driven microservices — 21% throughput gain, 18% cost reduction
- Enabled 50% faster vendor onboarding via a modular API platform (28+ fintech integrations)
Core stack: Java (8-21), Spring Boot/Cloud/WebFlux, Microservices, Kafka, REST/GraphQL/gRPC, AWS (EKS, Lambda, Bedrock, API Gateway), Azure (AKS, APIM), Kubernetes, Terraform, Docker
Currently specializing in Agentic AI and LLM integration (RAG/GraphRAG, LangChain4j, AWS Bedrock) — building intelligent automation and self-healing enterprise platforms.
AWS Certified Solutions Architect (Associate; Professional in progress). Comfortable as a client-facing architect across distributed, multicultural teams.
I can help you with:
- Solution architecture and cloud migration (AWS/Azure)
- Spring Boot microservices and event-driven architecture
- Agentic AI / LLM integration and RAG pipelines
- API strategy, governance, and secure design
- Legacy modernization (monolith → microservices)
- Zero Trust security architecture
- Technical leadership, architecture reviews, and mentoring
Let's talk about what you're building.
