I am a Senior Lead Engineer with over 13 years of hands-on experience designing and deploying production AI systems. My expertise spans the full stack of modern AI — from low-level CUDA GPU programming and embedded edge inference to cloud-native LLM applications with retrieval-augmented generation.

"Transforming complex real-world problems into measurable impact through machine learning and AI engineering."

Across my career I have built lane detection and autonomous driving systems, enterprise facial recognition platforms, IoT-powered toll management, and conversational AI chatbots that reduced customer query resolution time by 40%. I have a proven track record shipping models from experimentation to production on AWS, Azure, and GCP.

Currently deepening my work in Generative AI and LLM orchestration — building RAG pipelines, agentic systems (LangGraph, AutoGen), and multi-model deployments using LangChain, LlamaIndex, and AWS Bedrock. I believe the best AI engineering is invisible: it just works, reliably, at scale.

I thrive in cross-functional environments that bridge research and product — translating cutting-edge AI advances into tools real people use every day.
