Senior Engineering Manager at Atlan

I lead engineering teams building production AI agents — and I still ship the harness underneath them.

What I'm building · April 2026

About

Twenty years building. The last decade leading.

17+ years building bridges between data governance and engineering excellence. Today I lead AI-native context engineering at Atlan — 24+ engineers building the context layer for AI, unifying data products, domains, lineage, and contracts into a shared Enterprise Data Graph that organizations like Nasdaq, GM, FOX, Unilever, and HubSpot rely on. Over a dozen production agents now run on it. The harness we're building is taking customer-ticket resolution to ~5 hours with AI in the loop. In the year since I joined, Atlan moved from Visionary to Leader on the 2026 Gartner MQ for Data & Analytics Governance.

Before Atlan: nearly six years at Adobe — first as a Senior UI Engineer in the SF Bay Area shipping Adobe Experience Platform's ML workspace and Entity Lifecycle Management initiative, then as Software Engineering Manager (Remote, India) leading 12 engineers across Privacy, Unified Profile, Unified Permissions Framework, Use Case Playbooks, and Sandbox management. The platform serves The Coca-Cola Company, The Home Depot, GM, TSB Bank, MLB, Panera Bread, Henkel, Telefónica, T. Rowe Price, ServiceNow, and EY. Built the Bangalore and Noida teams complementing the US-side org.

Before Adobe: Staff Software Engineer at Juniper Networks (SF Bay, 2016–2019) — internal product manager + engineer for network editor, unified dashboard, visualization. Drove a 40% lift in development velocity, 30% reduction in licensing charges, 40% reduction in network authoring time. Built the Security Director mobile app that helped close two large enterprise accounts.

Before Juniper: six years at BMC, ending as Staff Specialist Product Developer — shipped a native Android app for ITSM (NPS +50%), led list-based asset visualization (retention +30%, churn −20%), built BMC's cloud lifecycle management portal and service designer (operations cost −80%).

What I care about: the system around the model. Models are commoditized — context engineering, memory, cost controls, observability are not. I still ship code in those layers myself, because directors who can't review a system design lose the room.
