Case Study
Overview
A marketplace that connects homeowners with contractors through an automated, invitation-based system—eliminating the spam of traditional job boards.
Challenge
The client wanted to avoid the crowded, low-trust feel of platforms like Angi or Thumbtack. Contractors should only see relevant jobs, homeowners shouldn't manually select contractors, and response times needed to be fast for home services.
Solution
Built a fully automated invitation system: job posted → eligibility filtering → ranking algorithm → wave-based invitations (2hr/6hr/12hr windows). Contractors only see invited jobs, homeowners get quality bids quickly.
Our Process
- Phase 1: NestJS backend with auth, projects, bids, escrow, Stripe Connect
- Phase 2: Next.js frontend with Shadcn theme, auth flow, responsive design
- Automated invitation logic with eligibility engine and ranking algorithm
- Webhook reliability layers for payment processing
- Mobile-first design for contractors in the field
Outcome
A clean, trust-focused platform where contractors receive qualified invitations and homeowners receive fast, quality bids.
