★ WebSockets & Real-time Technologies & Infrastructure 8-week engagement

REAL-TIME · WEBSOCKETS

# Real-time built for production. Consistency, reconnection, scale.

Live updates, presence, chat, and collaboration. The hard part is not the socket, it is consistency, reconnection, and scale. That is what we design for.

\[THE SHORT VERSION\]

## The socket is easy. The state is not.

Opening a WebSocket is trivial. Keeping clients consistent through reconnects, scaling fan-out across servers, and handling presence and ordering is the real work. We design those failure modes first, often using Durable Objects or Redis for coordination.

When it fits

-   Chat, presence, and live dashboards
-   Collaborative editing and multiplayer features
-   Anything where polling is too slow or too costly

\[HOW WE BUILD IT\]

## How we build with WebSockets & Real-time.

01

### Scope and fit

We decide where WebSockets & Real-time earns its place in your system, and where a simpler tool wins. No resume-driven architecture.

02

### Build on a tested foundation

We integrate WebSockets & Real-time against a foundation we trust: typed code, CI, and observability from the first commit. Boring infrastructure, modern surface.

03

### Eval before launch

An eval suite proves the build behaves before it reaches a user. We measure, then ship.

04

### Handoff with ownership

Your team gets the code, the tests, and a runbook. No lock-in to us or to a vendor framework.
