About Me
Marc Hayes is a full-stack developer who builds web and mobile apps. Passionate about taking ideas from concept to shipped product, he thrives on turning ambitious visions into polished, real-world applications.
He works across the entire stack — from React and Next.js on the web to Swift and React Native on mobile, backed by modern cloud infrastructure. Every project is an opportunity to craft something that people actually want to use.
Whether it's a SaaS platform, a native iOS app, or a full-featured web experience, the goal is always the same: ship quality software that solves real problems.
