About Me

Senior Fullstack AI Engineer and Solution Architect building the next generation of enterprise intelligence systems — where large-scale LLMs meet production-grade engineering.

I design multi-agent orchestration platforms, RAG knowledge pipelines, and document intelligence systems that process millions of records. My work spans from the model layer — fine-tuning embeddings, crafting agent graphs — all the way to the infrastructure layer, deploying on Kubernetes across AWS and Azure.

I think deeply about system design: not just making AI work, but making it reliable, observable, secure, and scalable for real-world enterprises. Banking, Telecom, Insurance, Retail, Fintech — I've shipped across all five domains.
