About Me

Clarity Through Connection.

A data and analytics consultant who believes the best insights come not from algorithms alone, but from the marriage of analytical rigor and human wisdom.

About Me

For over 17 years, I've worked across manufacturing, banking, retail, healthcare, automotive, and technology — helping organizations turn complex data into clarity, strategy, and meaningful business decisions.

But what truly defines my work lies beyond dashboards and analytics.

As a meditation teacher and mindfulness practitioner, I bring a rare blend of analytical depth and human awareness into every engagement. I believe the ability to understand people is just as important as the ability to understand data.

The same stillness that deepens mindfulness also sharpens insight, reveals patterns, and helps build systems that genuinely serve human needs.

Today, I work at the intersection of data, leadership, systems thinking, and conscious transformation — through consulting, teaching, writing, and mentoring clients worldwide.
