Leadership narrative

Engineering leader with 19 years building and scaling SaaS platforms and the organizations behind them. Shipped a production ML scheduling system for 20,000+ field technicians at Verizon years before AI was a boardroom priority, then scaled a Trimble cloud platform team 6× (5 → 30 engineers) while adding $28M in net-new ARR.

Most recently launched a Built To Order AI business from 0→1 with 5 paying enterprise customers at 40% operating income, delivering custom AI solutions as a new high-margin revenue line. Known for turning customer commitments into shipped product, retaining top talent (92%), and embedding AI into how teams build, not just what they build.

Title is Engineering Director; operating scope has consistently exceeded that band. India Engineering Council representative for 500+ engineers for more than 6 years, leads a Trimble India–level high-performance culture initiative, authored org-wide engineering playbooks, and partners on a $50M ARR portfolio. Functioning at Senior Director / VP scope for more than a year.
