Gaurav Walawalkar manages high-stakes financial operations by blending systems architecture with strict fiscal discipline. His career focuses on building the control systems that allow enterprises like Amazon and American Airlines to scale their technology footprint without eroding profit margins. At Amazon, Gaurav authored the long-range financial roadmap to move a business segment from a $200 million baseline toward a $12 billion revenue goal, managing a combined portfolio of nearly $1.2 billion in revenue and operating expenses. Moving past manual spreadsheets, he engineered an automated transaction policy that acts as a real-time margin filter. This system programmatically screens out low-yield commercial bids to protect profitability during high-volume growth phases. Earlier, at American Airlines, Gaurav led a fundamental restructuring of how the airline evaluates its underlying technology assets. Serving as the Functional Product Owner for the enterprise Apptio deployment, he managed the migration away from legacy annual project funding into an agile, product-centric total cost of ownership model. This taxonomy gave engineering leaders instant visibility into unit-level infrastructure consumption across complex hybrid cloud environments.
