Madhu Dharmarajan

Founder & Principal Consultant

28 years of enterprise architecture, digital engineering, and transformation consulting.

28 years. Six sectors. Twelve enterprise clients. Madhu Dharmarajan has spent his career at the intersection of architecture and transformation — leading the work that turns strategy into systems, and ambition into delivery. He has operated across the UK, India, Japan, Singapore, and APAC, building and leading the architecture teams that make complex change executable.

Senior roles at EY, Hewlett Packard Enterprise, Barclays Investment Bank, Wipro Consulting, Lloyds Banking Group, Capital One, Vodafone Japan, Oracle, and Deutsche Bank. The breadth is deliberate — financial services, energy, healthcare, public sector, and technology each demand a different kind of rigour. Icehusk brings all of it.

Published author. Public speaker. Thought leader in enterprise architecture. The work is serious, the track record is real, and the approach is always the same: architecture first, execution always.
