★ TypeScript Languages & Frameworks 8-week engagement

TYPESCRIPT · TYPED EVERYWHERE

# TypeScript end to end. Shared contracts, refactor-safe, real types.

We write TypeScript everywhere it runs: frontend, backend, edge, and tooling. Types are the cheapest tests you will ever ship.

Stack

Strict TypeScript

Output

Production code + eval suite

Handoff

Full source ownership

\[THE SHORT VERSION\]

## Types catch a whole class of bugs before they exist.

TypeScript earns its keep by making invalid states unrepresentable and refactors safe, not by adding ceremony. We run it strict, and we share types across the network boundary so the client and server cannot drift.

When it fits

-   Any JavaScript codebase expected to live past a prototype
-   Teams that refactor often and want safety
-   Shared contracts between frontend and backend

\[HOW WE BUILD IT\]

## How we build with TypeScript.

01

### Scope and fit

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

02

### Build on a tested foundation

We integrate TypeScript 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.
