Eric Lewis is a Senior II AI Design Engineer with 14 years of hands-on experience building mobile-first products, developer tooling, and production architectures across startups and scale-ups. He’s led mobile teams and major migrations (Objective-C to Swift, native to React Native) while shipping high-quality apps used by millions and maintaining exceptional reliability. Eric combines product-facing iOS and cross-platform expertise with backend and API design—having driven adoption of GraphQL, modular architectures, and SwiftUI/Compose patterns at scale. He’s an active open-source contributor, improving iOS stability in React Native and enhancing SwiftUI apps like an Animal Crossing companion, showing attention to both UX polish and low-level robustness. Known for pragmatic engineering leadership and mentoring, he also quietly builds SDKs and internal tools (including an unreleased easy-to-use Cosmos SDK) that accelerate teams behind the scenes. Based in Acworth, GA, he blends research-minded R&D work at the intersection of life and machine with a knack for untangling thorny build and compatibility issues.
