About

Payment platform engineer driving AI-augmented engineering practices. 14+ years building mission-critical systems at Adobe, Barclays, Paytm, and Citi — now combining deep domain expertise with AI to transform how engineering teams work.At Adobe, I lead payment revenue recovery programs (ABM Revival, SPM, PPD, EGP, FlexFactor) impacting millions of subscribers globally — owning end-to-end delivery from blueprint design and quarterly sizing through geo-expansion across 90+ countries, working directly with product, business, and cross-functional teams. In parallel, I am building the AI infrastructure that powers our team: an AI Skills marketplace, RAG-powered knowledge systems for automated feature sizing and research, lightweight MCP servers, and context-engineered workflows across Claude Code and Cursor IDE. I enjoy solving problems that sit at the intersection of distributed systems and real-world constraints — handling failures gracefully, making consistency and availability trade-offs, and evolving systems without disrupting live traffic. My day-to-day spans deep backend implementation, architectural reviews, production readiness, quarterly initiative sizing, and mentoring — alongside driving AI adoption across the team. I believe the most impactful engineers are the ones who understand the domain deeply enough to know what to automate — and what not to.
