Ryan A. Koval

Software Engineering, Architecture & Management

Ryan is a software engineering leader with 15+ years of experience across architecture, product, and engineering management. His career spans consulting, startups, acquisitions, and hyperscale platforms, with a consistent focus on turning complex technical domains into durable products that serve real business needs.

He brings first-hand startup-to-acquisition experience from Guilded, where he helped build and scale the product through its acquisition by Roblox, then expanded into engineering leadership on larger cross-functional platform work. Today at NVIDIA, he leads product engineering for internal automation used to operate some of the world's most demanding AI infrastructure.

Across roles as engineer, manager, founder, consultant, and CTO, he has stayed close to both the code and the customer. He is strongest where technical execution, product judgment, team development, and business context all matter at once.

Roblox began to grow rapidly in the second half of the 2010s, and this growth has been accelerated by the COVID-19 pandemic. Roblox is free to play, with in-game purchases available through a virtual currency called Robux. As of August 2020, Roblox had over 164 million monthly active users, including more than half of all American children under 16. Although Roblox has received generally positive reviews from critics.
