HipHopGrails
The flagship auction destination for hip-hop memorabilia and celebrity drops — engineered on Azure, .NET, Next.js and PostgreSQL.
HipHopGrails is the breakout auction platform for hip-hop culture — the first destination of its kind, often described as the Sotheby's of the streets. We built it end-to-end on a Microsoft Azure cloud, with a .NET microservices core, a Next.js front end and a PostgreSQL data layer. From the bidding engine to consignment workflows, identity, escrow and live event run-of-show, every layer is ours.
