About

I help product and platform teams move faster, scale smarter, and deliver more value to customers. With 30 years of experience—from launching hit games to leading engineering transformations—I specialize in turning early-stage ideas into customer-ready products and building teams that scale. I’ve led zero-to-one platforms that drove 10X revenue growth, cut costs while maintaining velocity, and mentored engineers and leaders into new roles. Through strategic consulting and fractional CTO work, I’ve supported enterprise initiatives at Clorox Corporation, Samsung, Verizon, and Activision-Blizzard—bringing clarity to complex systems, unlocking efficiency, and shipping outcomes that matter. Whether it’s personalization, infrastructure, or bleeding-edge prototypes, I blend hands-on execution with executive vision to align product, people, and process around measurable customer impact.
