About Anjan Chatterjee

Healthcare Data and ML/GenAI Architect focused on solving real problems with the right technology, not the newest for its own sake.I design and deliver secure, governed platforms that unify data across complex healthcare ecosystems and translate analytics and AI into capabilities that people actually use in their workflows. My work centers on three outcomes: faster operations, better quality, and sustainable cost performance.I\'ve led architecture for multiple business-critical implementations where the stakes are high: patient care systems, regulatory compliance, operational resilience. In these environments, I set technical direction and delivery standards across data governance, security, auditability, and monitoring. Beyond delivery, I contribute to the research community through publications on governed GenAI, healthcare architecture patterns, and operational AI deployment at scale.
