About Me

Organizations today sit on massive amounts of data, but struggle to connect the dots — cleaning, linking, and turning it into real decisions is often slow, messy, and expensive.

I solve that problem by building scalable, interoperable data systems that transform raw inputs into insightful dashboards, predictive models, and decision tools. My work bridges data architecture, analytics, and strategy, ensuring leaders can act quickly with confidence.

I’m Sri Hari Sivashanmugam, a Data Scientist & Consultant with expertise in public health, government, and mission-driven organizations. My approach is simple: tackle complex data challenges with clear, actionable solutions that deliver measurable impact.
