Problem
AUB students arranging carpools had no dedicated platform - coordination happened informally, with no reliable way to find nearby drivers, verify identity, or rate ride partners.
Solution
AUBus Premium uses a hybrid client-server/peer-to-peer architecture: a multithreaded TCP server handles registration, OTP email verification, Google sign-in, and ride matching by area, time, and minimum rating, while drivers and passengers exchange text, voice, image, and location messages directly. The platform also supports group chats, a car catalogue, license-plate verification, live weather lookups, light/dark mode, and full English/Arabic/French localization.
What I Learned
Designing a custom length-prefixed JSON-over-TCP protocol made the value of explicit state machines clear - modeling the ride lifecycle as pending -> accepted/rejected -> active -> completed kept the client and server consistent under concurrent requests.
