My Days — personalised feed

Replaced a reverse-chronological feed with a scoring pipeline. Six signals, interest learning per user, a diversity pass so one author can’t dominate, and a penalty for posts you’ve already seen.

GreenBidz

A live bidding platform. Two bids can arrive in the same tick, so bid acceptance is serialised server-side and every client converges on the same state rather than the last write winning.
