An engineer who learned
to sell. Then to keep.
Then to grow.

Fifteen years. Three industries. One relentless obsession with revenue that compounds.

Fifteen years across IT infrastructure, EdTech, and SaaS — starting on hardware floors in Chennai, moving through enterprise sales, and eventually leading CS and revenue functions at Chargebee and Murf.ai. I've done the $1M→$100M journey twice, building teams across India, the US, and Amsterdam along the way.

My edge is knowing both sides of the revenue equation — how to win the deal and how to keep and grow it. At Chargebee I took a fragmented CS org to 140% NRR and a President's Club sweep. At Murf.ai I built the entire CS and Sales Development function from scratch, taking NRR from 114% to 128% in the first year — AI-first, lean, and built to scale.
