The entire visual side of my fitness-and-nutrition app is already completed, and a portion of the front-end code is in place. What I now need is an experienced full-stack mobile developer who can take these designs and turn them into a fully working product for both iOS and Android. Here is where we’re starting and where I need your expertise: • User accounts must support both email/password and the usual social logins, with profiles that store workout history and recipe favourites. • Payments have to work smoothly for European users—think Stripe, Mollie, or any reliable gateway you can recommend that handles subscriptions and one-off purchases. • An admin panel / CMS is essential so I can upload workout videos, cooking clips and full recipe lists without touching code. • Video hosting and adaptive streaming should be streamlined; please advise on the best balance of cost and performance (AWS, Cloudflare Stream, Vimeo Pro, etc.). • You’ll set up the database, API layer, and any server-side logic needed to knit the front-end together. • Basic analytics and user management tools should be baked in from the start so I can track active users and subscription churn. • Finally, you’ll guide the build through TestFlight / Google Play Console all the way to live deployment, or suggest a cross-platform alternative if it speeds things up without sacrificing quality. I’m looking for someone who can think past the short term, propose a scalable architecture, and deliver an MVP that grows easily as my content library expands. If you have solid experience with subscription apps, video streaming, and admin dashboards, let’s talk through your approach and timeline.
