Handees is a "service-hailing" marketplace (think Uber for artisans) that connects users with verified professionals on-demand. The core technical challenge was latency. Unlike a standard directory, Handees required:
Instantaneous communication between users and providers.
Live location tracking and status updates.
Scalable infrastructure that could handle traffic spikes without incurring massive idle server costs.
🛠The Build (My Solution)
I architected the entire backend from the ground up, focusing on a serverless, event-driven approach.
Real-Time Engine: I bypassed standard polling by implementing a bidirectional communication layer using SocketIO backed by Redis Pub/Sub. This allowed chat messages and order updates to be delivered in milliseconds.
Serverless Runtime using GCP cloud run.
