WebSockets Specialist

A WebSockets specialist builds the real-time features that make an app feel alive: live chat, collaborative editing, trading dashboards, multiplayer games, delivery tracking, and instant notifications. Instead of a page asking the server for updates over and over, you design connections that stay open so data can flow both ways right away. Your days include writing server and client code, deciding how messages are structured, handling disconnects and reconnects, testing under heavy load, and watching how the system behaves when thousands of users are connected at once. You work closely with front-end developers, infrastructure engineers, and product managers.
