Summary
🤩
RockstarDavid Roman is an experienced iOS engineer with 11 years in software and over five years building large Swift apps used by millions. He has led architectural overhauls—refactoring legacy UIKit codebases into modular MVVM and TCA architectures—to improve developer velocity, testability, and long-term maintainability for consumer and crypto products. As a hands-on engineer and former CTO/co‑founder, he shipped SwiftUI apps early in the framework’s life and published complementary open-source libraries to address gaps he encountered. His work spans high-scale consumer features (search, visual fit, payments) and security-sensitive crypto flows, including multi-step signing and hardware wallet support with automated tests. Comfortable delivering under tight deadlines, he also brings product instincts from founding a marketplace and collaborating across web, extension, and mobile teams. Colleagues rely on him for UI craftsmanship, animation-heavy experiences, and pragmatic architectural guidance.
