I sit on the client side of the table. Presales, solution consulting and client engagement for enterprise technology programmes — since 1983.
AI-accelerated delivery. Human-grade judgment. Since 1983, knowing the difference.

Every seat at the table
I started in 1983 in Chennai, writing financial accounting, costing and share accounting systems — the kind of work where a wrong number is visible immediately. Twelve years later I was in Silicon Valley, first as a DBA migrating three thousand production databases for a telecom carrier, then architecting reverse logistics and order fulfilment for Hewlett-Packard across the Americas, Europe and Latin America.
​
In between I built things that had to be sold: a California division from nothing to $1.2 million in three years, an India development centre from zero past two hundred people, a data warehousing practice that grew fivefold in three. And I ran presales for an enterprise software services division, reporting to its CEO.
​
So I have been the vendor and I have been the buyer. I have written the proposal and I have been the client reading it, knowing exactly which paragraph was doing the work. That is the seat I choose now — the one in front of the client, where the question is what should be done rather than how to staff it.
​
MarkerIT has been the vehicle for that since 2004.
What I do
Four things
Presales and solution consulting. Shaping the pursuit, the solution and the commercial story before the proposal is written. Set up the presales function for an enterprise software services division and ran it reporting to the CEO; secured a first international client in Belgium's publishing and broadcasting sector; opened a first Microsoft Dynamics HR and payroll account in the UAE.
​​
Client engagement and executive relationship. Holding the relationship above the delivery line — the conversation the delivery manager cannot have. 100% retention across multinational accounts in two separate periods, with 250% growth on those accounts.
​​​
Independent programme review. A written verdict on what is actually wrong with a programme, from someone who is not running it and will not bid to fix it. Recovered a derailed sales-and-marketing rollout for a multinational financial-services conglomerate; lifted profitability fifteen per cent by closing non-profitable projects.
​​​
Sounding board to owners and founders. The conversation a principal cannot have inside their own company.
​
How I work
Three principles, and one habit
Holistic, high-calibre, honourable. In practice that means the finding goes in the report even when it ends the engagement.
​​
No stake in the recommendation. If a review concludes that a vendor should be replaced or a programme stopped, MarkerIT will not be bidding for what follows.
​​​
Priced as engagements, not as a headcount line. Scope and fee agreed in writing before work starts. That is how MarkerIT has operated since 2004.
​​​
The Habit: Management by walking around, with the go-and-see principle borrowed from the Toyota Production System.
