Executive Summary
Strategic, hands-on IT executive with 45 years of technical delivery, engineering, and global IT services leadership — a career that began as a programmer in Chennai in 1983 and now spans continents, industries, and every major shift in enterprise technology since. A proven track record as a Delivery Head steering large-scale digital transformations, enterprise data migrations, and high-volume transaction processing systems for global Fortune 50 corporations, banking institutions, and non-profits across several countries.
​
Deep architectural expertise spanning .NET with Azure Cloud ecosystems, Big Data pipelines, and Conversational AI frameworks. Adept at scaling technology practices from scratch, managing large multi-disciplinary teams (300+ members), and serving as a trusted strategic advisor to C-suite and global stakeholders.
"
Nearly 30 years with one organization, while running an independent practice in parallel. The relationship with Congruent runs continuously from 1995 to today — Director of Strategic Consulting, then Technology Head, now VP of Delivery & Technology Engineering — the entire time also building and owning MarkerIT as a separate consulting practice since 2004. Very few people sustain both threads at once for two decades running.

BEYOND THE DELIVERY SEAT
Advisory & sounding board roles
Consistent with the "Sounding Board Services to Business Owners and Founders" line on LinkedIn — these are advisory relationships, not employment, kept separate from the career timeline above for that reason.
