The challenge

Saudi Arabia's construction industry had no digital marketplace. Clients couldn't find verified contractors, contractors depended on referrals, and there was no transparent pricing or bidding system.

  • No reliable way to discover and verify local builders and contractors
  • Contractors dependent on offline referrals — no digital visibility
  • No structured project posting or RFQ system
  • No trust layer — no verification, ratings, or reviews for contractors
What we built

DH Solutions built an Upwork-style two-sided construction marketplace — connecting homeowners and developers with verified contractors through structured project posting, bidding, and real-time communication.

  • Project posting system with budget, timeline, location, and attachment support
  • Verified contractor profiles with service categories, portfolio, and ratings
  • Competitive bidding system — contractors submit proposals, clients compare
  • Negotiation workflow between clients and contractors
  • Real-time messaging via WebSockets with project-based threads
  • Admin panel — verification, dispute handling, analytics, and moderation
