Real-Time Technician Booking Platform
Sep 2024 – Apr 2025 · Final Year Project
Overview
A home-services marketplace connecting customers with service providers — plumbing, electrical, painting, and similar work — through competitive bidding rather than fixed pricing: a customer posts a job, providers counter-bid in real time, and the customer accepts and pays through the platform.
- Engineered an on-demand labor services platform on the PERN stack supporting 100+ concurrent users at 99.9% uptime.
- Implemented real-time price negotiation and emergency service prioritization via Socket.io, reducing average response time by 40%.
- Integrated a secure payment flow processing 500+ transactions per month.
Approach
- Built real-time bidding and counter-offer negotiation with Socket.io so customers and providers see price updates instantly instead of polling or refreshing.
- Modeled three distinct roles — customer, provider, and admin — with separate auth and permissions on a single PERN-stack codebase.
- Integrated a payment flow so an accepted bid converts directly into a paid booking without a separate checkout step.
