Technology Expertise

▸Java Ecosystem: 25+ years with Spring Boot, J2EE, microservices, and cloud-native architecture
▸Cloud Platforms: Multi-cloud expertise across AWS, GCP, and Azure with Kubernetes orchestration
▸DevSecOps: Built security-first CI/CD pipelines reducing vulnerabilities by 45%

AI/ML Innovation

▸Generative AI: Production RAG systems, fine-tuning with LoRA, self-hosted LLMs
▸AI Security: Novel LLM-based threat modeling and vulnerability detection in CI/CD
▸MLOps: End-to-end pipelines from experimentation to production deployment

Tech Stack

With 25+ years of enterprise delivery, I favor pragmatic architecture choices over trend chasing.

I build durable platforms with clear trade-offs, biasing for security, observability, and performance at scale.
