If you are looking for a senior technology consultant who has spent 18 years at Wipro building, selling, and delivering enterprise cloud and automation solutions — you have found the right profile. I am not a generalist. I bring deep, hands-on expertise across four high-value disciplines that most consultants offer separately: What I deliver for clients: Cloud Architecture & Implementation — I design and implement hybrid cloud solutions across AWS, GCP, and Microsoft Azure. My architecture work spans IaaS, DR/HA, multi-site backup, HCI, and Pay-as-you-Go commercial models. I have delivered 4,000+ Infrastructure-as-Code automation assets across public cloud and on-premises environments. Cloud & Managed Services Automation — I built an Infrastructure Automation Accelerator from scratch inside Wipro — a platform enabling managed services teams to deliver automated IT professional services across a client's technology estate. I understand automation from product design to customer deployment. Pre-Sales & Solution Architecture — I have spent years translating complex technical architectures into winning commercial proposals. I understand RFPs, bid defense, BOMs, RACI matrices, resource loading plans, and what it takes to win enterprise deals. I won a USD 500 million total outsourcing deal. AI-Augmented Consulting — I use Claude, ChatGPT, Gemini, and Grok as active working tools — not buzzwords. I deliver research, analysis, presentations, reports, and strategic documents significantly faster than traditional consulting, without sacrificing quality. Why clients choose me over other consultants: First — 18 years at Wipro as a Tier-1 global IT organization means I have worked at enterprise scale. I understand how large organizations think, buy, and implement technology. I do not need to learn your world from scratch. Second — I have operated across the full commercial lifecycle — from pre-sales pitch to alliance negotiation to product P&L to customer delivery. I can engage credibly at every level of your organization. Third — I am AI-augmented. Every engagement I take benefits from my applied AI toolkit — faster research, sharper documents, and more rigorous analysis than a traditional consultant working alone. Verified achievements: → USD 500 million total outsourcing deal — Wipro/Uninor, FY2009 → 4,000+ IaC automation assets delivered across AWS, GCP, Azure → 145% of annual sales target as Solution Architect → 125% of annual sales target in first year as Pre-Sales Manager → Harvard Division of Continuing Education — Product Management certification → AWS Certified Solutions Architect — Associate → Google Cloud Digital Leader + 6 Google Cloud certifications → 5 published Wipro whitepapers on cloud, automation, and data management How I work: I work fully remotely and am available for clients globally across all time zones. I am comfortable with async communication, structured deliverables, video calls, and milestone-based engagements. I deliver on time, communicate proactively, and treat every client engagement as a long-term relationship — not a transaction. Engagements I am well suited for include cloud architecture consulting, automation strategy and implementation, pre-sales support, solution design, RFP response, product management advisory, and AI-augmented research and analysis. Ready to start a conversation? Send me a message describing what you are trying to solve. I will respond within 24 hours with a clear view of whether and how I can help — no commitment required.
