E-Sports Tournament App Development

I'm creating a dedicated platform for running online e-sports tournaments and I’m looking for a developer who can take it from concept to a polished, production-ready release.

Core scope
• Tournament flow: create brackets, schedule rounds and progress winners automatically.
• Team management: captains sign up their rosters, edit player details, and handle substitutions inside the app.
• Secure entry: each event generates a unique code or password; only users with that code can join.

While those three items are mandatory, I’m open to your ideas on extras—live leaderboards, chat, or even streaming hooks—provided they don’t slow down the main release. I’m flexible on stack; if you can justify Flutter, React Native, or a web-first SPA with a shared backend, I’m happy to discuss. Code needs to be clean, documented, and deployable to both iOS and Android stores (or web, if you pitch a PWA).

When you reply, please share:
• Your proposed architecture and any third-party services you’d lean on for auth, real-time updates, or cloud storage.
• A timeline that breaks down design, core build, testing, and launch.
• Links to previous tournament, gaming, or event apps you’ve shipped.

I’ll provide detailed wireframes and branding once we agree on direction. Looking forward to collaborating and getting the first tournament live soon.
