What I'm looking for

I'm seeking senior leadership roles in analytics, data science, AI, or operational intelligence, where I can build scalable predictive solutions and turn complex data into proactive decisions.

At Enphase Energy, I lead near-real-time analytics for 86M+ connected energy devices serving 5M+ customers, turning five-minute telemetry into early detection of fleet and product issues. I architected automated root-cause detection with more than 95% remote diagnostic accuracy and an RMA intelligence platform that replaced a two-day-to-two-week manual process.

I've spent 21+ years building analytics systems, including 16+ years in energy and renewable energy. From predictive failure detection and AI call intelligence to Tata Power Solar's early remote-monitoring infrastructure and Infosys data platforms, I focus on finding unusual patterns, understanding why they happen, and turning them into scalable operational decisions.
