The story behind the data.

I'm a Generative AI & AI/ML Engineer based in Boston, with experience delivering production-ready solutions across Databricks, Azure, AWS, and GCP.

Currently at Databricks, I design and deploy RAG pipelines, LLM-powered applications, and vector search solutions — building enterprise chatbots, semantic search tools, and document intelligence workflows that process 10M+ records daily.

Before that, I built AI/ML solutions for healthcare and life sciences at Verily, improving prediction accuracy by 25% through end-to-end ML pipelines and responsible AI practices.

I hold an MS in Data Analytics Engineering from Northeastern University, and I'm certified across Databricks, Azure, and Google Cloud's Gen AI and ML platforms.
