Stats-Driven M7 Rating Website

I want to launch “M7 Rating,” a modern, minimalistic site that converts a player’s Premier statistics from Tracker.gg into a single M7 score on a 22.8-point scale. The site must pull data only from Tracker.gg Premier, apply the rating formula, and display the result on each player’s profile.

Account flow is straightforward: new users register with a display name, Discord handle, and their Tracker.gg profile link. Only those who register are tracked. Discord information remains hidden from the public and is visible only to me (the owner) and any users I promote to “team manager.”

Inside my owner dashboard I need to:
• create and edit teams
• assign or remove players from those teams
• promote or demote users between “player” and “team manager” roles

Team managers gain visibility of their roster’s Discord handles but no wider admin rights.

The UI should feel clean and uncluttered—think generous white space, crisp typography, and intuitive navigation that works on desktop and mobile. I’m open on the tech stack; just outline the framework (React, Vue, Next.js, etc.), backend language, database, and how you’ll schedule or cache Tracker.gg API calls while respecting rate limits.

Acceptance criteria
• Secure sign-up/login capturing the three required fields
• Automated stat pull and M7 calculation, refreshed on a reasonable schedule
• Role-based permissions exactly as described
• Owner dashboard and team-management tools fully functional
• Responsive, modern/minimal design matching the site theme

Tell me how you plan to build it, any similar projects you’ve delivered, and an estimated timeline from kickoff to launch.
