Real-Time Updates With WebSockets, Replacing Client-Side Polling
Company and product names are withheld under NDA. The problem, solution, and my role below are real, from my day-to-day work leading a 4-person backend team within an 11-person cross-functional org at a growth-stage startup.
The business problem
The product relied on client-side polling to stay up to date, which meant redundant API calls, unnecessary server load, and a noticeable lag between something changing and the UI reflecting it.
The solution
I replaced the polling approach with WebSocket-based real-time communication, so the backend pushes updates to connected clients the moment data changes, instead of clients repeatedly asking if anything is new.
My role
I led the 4-person backend team responsible for this system end-to-end — architecture, implementation, and rollout — within an 11-person cross-functional org.
Technical challenges
The main challenge was connection lifecycle management at scale — handling reconnects and delivering updates reliably to many concurrent clients without polling left in place as a fallback crutch.
Results
Redundant polling traffic was eliminated entirely, and users got instant data updates instead of waiting on a fixed refresh interval. This same backend also powers an AI-assisted search case study → for the same platform.
