I’m a product and data leader with nearly two decades of experience building data platforms, analytics systems, and data-driven products. I started my career in Unit 8200 and later led data and product initiatives at companies like Sisense and ZipRecruiter, where I headed product for data, ML, and experimentation platforms. Today, I advise startups and growing tech companies on product strategy and data infrastructure, helping teams turn data into a real driver of decision-making and impact. I’m especially passionate about bridging product thinking and analytics, and empowering teams to operate with clarity, ownership, and measurable outcomes.
