Full Stack Developer - Sports Broadcasting Schedule Site

I am looking for an experienced full stack developer to build a sports broadcast schedule website from the ground up. The concept is simple but powerful: sports fans waste time trying to figure out where to watch their favorite sport on any given day. Schedules are scattered, streaming deals change constantly, and nobody knows what channel anything is on. This site fixes that. Users come to the site, find their sport or series, and instantly see the full schedule with every broadcast option — network TV, streaming platform, and the actual channel number for their cable or satellite provider — with one tap links to watch. The site covers every major sport: all of motorsports (Formula 1 and all feeder series, full NASCAR ladder, IndyCar, MotoGP and feeder series, DTM, ELMS, GT World Challenge, and more), NFL, NBA, MLB, NHL, MLS, Premier League, Champions League, college football, college basketball, and dozens more. New sports are added on a rolling calendar before each season starts. Core features include a personalized homepage showing what is on this weekend, a live tab with an ESPN-style grid of upcoming events, full series and league pages with schedules and broadcast info, a channel number guide for all major TV providers, user accounts with Google and Apple sign in, a follow system so users see their sports first, and saved preferences across sessions. The tech stack is Next.js, Supabase for database and authentication, API-Sports for live schedule data, Tailwind CSS for styling, and Vercel for hosting. I have detailed project specifications, full design mockups, a complete series list with brand colors, database schema, streaming platform links, and channel number tables ready to hand over immediately after signing a standard NDA. I am a non-technical product owner. I know exactly what I want and will give fast clear feedback throughout the build. I need a developer who communicates proactively, follows a detailed spec closely, and can make smart technical decisions independently. Fixed price bids only. Please include two examples of live web apps you have built and your estimated timeline.
