Nick Kaffine
Nick Kaffine is a Lead Mobile Engineer at Chalkboard focused on building and scaling mobile applications. He previously led mobile engineering efforts at Flexcar, including migrating native iOS and Android apps to React Native and evolving product architecture to support rapid iteration. His work sits at the intersection of engineering, product, and design, with a focus on making practical tradeoffs that balance developer velocity, user experience, and business impact. He is particularly interested in how those tradeoffs play out in real-world systems and how they shape the products teams ultimately build.
The UI Was Beautiful. The Frame Rate Wasn’t. Here’s Why We Didn’t Fix It.
This talk breaks down how a React Native app optimized for developer experience, iOS-heavy users, fast iteration, and polished, visually rich UI ended up with user-visible performance issues that we never fixed. Not because we ignored them, but because we never made them measurable enough to compete with feature work.
