Turning business requirements into Azure solutions customers can buy

I'm an Azure Presales Solution Architect with nearly 17 years in cloud architecture and enterprise infrastructure, currently a Cloud Solution Architect at HCL Technologies.

I lead presales engagements end to end: customer discovery, architecture workshops, RFP and RFI responses, estimates, TCO and ROI analysis, and client presentations. My designs cover landing zones, hybrid networking, security, governance, migration and modernisation, built to be secure, scalable and commercially viable.

Hands-on depth in Terraform, Azure DevOps and Infrastructure as Code lets me validate solutions with proofs of concept and hand them over cleanly to delivery.
