What I'm looking for

I seek engineering roles where I can build and lead AI-driven, scalable systems, mentor teams, and deliver measurable product and operational improvements in secure, cross-functional environments.

I am a Senior AI and Full-Stack Engineer with 9+ years building scalable, cloud-native systems across fintech, retail, and healthcare, delivering production-grade services and ML-driven products that serve millions of users.

I design and ship end-to-end solutions — from microservices and real-time APIs to LangChain/RAG LLM agents and MLOps pipelines using MLflow, Ray, HuggingFace, and Pinecone — that reduced failures, triage time, and latency across multiple products.

I lead cross-functional initiatives, mentor engineers, and integrate secure payment and compliance workflows (PCI, HIPAA, SOC 2, GDPR) while leveraging AI coding assistants to accelerate delivery and improve engineering quality.
