I’m ready to launch an integrated gym management solution that covers a browser-based admin portal for owners and trainers plus companion mobile apps for members on both iOS and Android. Core functionality must include: • User registration and profile management for owners, trainers, and members • Workout tracking so members can log exercises, sets, reps, and progress • Class schedules with real-time booking, wait-listing, and trainer assignment The web interface will serve as the control center—creating classes, managing memberships, viewing attendance, and pulling basic analytics—while the mobile apps should mirror the member-side features in a clean, intuitive UI. I have no legacy systems to integrate, so you can choose the stack you’re most comfortable with as long as it is well-documented, secure, and scalable. When you respond, attach a detailed project proposal outlining: • Suggested tech stack for web and native/hybrid mobile builds • High-level architecture diagram • Milestone plan with estimated timelines • Any past work that demonstrates similar multi-platform deployments I will shortlist based on how clearly you address the above and how well your plan anticipates future feature additions like payment processing or wearable integration. Looking forward to reviewing your approach.
