Hey! I’m Julien — a mobile developer with 8 years of experience building apps people love to use. I spent five years as co-founder of Revolt Games, where I built Neopolis, a real-world strategy game that grew to 5M players, raised $3M+, and was featured twice in Apple’s Best Games. Now I work as a freelancer and building apps through my studio Appton, usually with my dog Shelby sleeping next to my desk 🐶. What I bring: • Strong mobile expertise (Flutter) • Fast execution and clean architecture • A product mindset (not just coding) • Great communication & transparency • Reliable delivery (startup founder discipline) What I can do for you: • Build your entire app (MVP to production) • Improve UI/UX and animations • Optimize performance • Add features or refactor code • Publish and manage store releases • Work long-term as part of your team If you’re looking for someone senior, fast, and easy to work with — I’d love to join your project.
