Lead Data Scientist \| GenAI Architect \| LLMs, RAG, Agentic AI Systems \| Driving $M\+ Business Impact through AI Innovation

## About

Lead Data Scientist with 12\+ years of IT experience, including 8\+ years specializing in AI/ML and Generative AI, delivering enterprise\-scale AI solutions with measurable business impact\. My core expertise lies in designing and deploying LLM\-powered systems, RAG architectures, recommendation engines, and end\-to\-end AI platforms that improve efficiency, automation, and revenue outcomes\. I have built and scaled GenAI\-driven systems across enterprise environments, including LLM\-based workflow automation \(Excel, PDF, Email\), scalable RAG frameworks using Azure OCR and Azure GPT, and recommendation engines using LightFM that directly contributed to business ROI improvements\. My work spans both predictive analytics and GenAI innovation, enabling organizations to move from experimentation to production\-grade AI adoption\. Beyond model development, I have led AI roadmap initiatives, stakeholder engagements, and cross\-functional collaborations across marketing and product teams\. I actively contribute to mentoring data science teams and driving AI adoption strategies that align with enterprise goals\. I am currently targeting senior roles such as GenAI Engineer, GenAI Architect, and Lead Data Scientist, where I can continue building impactful AI systems that combine innovation, scalability, and measurable business value\.
