Type-safe JavaScript across the whole stack, for fewer bugs and safer change.
Overview
TypeScript adds static types to JavaScript. Types are checked when the code is built and then removed, so the result is ordinary JavaScript that runs anywhere JavaScript does.
Teams adopt TypeScript because it catches whole classes of bugs before code ships, makes refactoring far less risky and documents how code is meant to be used. On codebases with several developers, it is one of the cheapest quality improvements available.
What we build
Shared types and schemas from database to API to UI, so a renamed field shows up as a compile error, not a production bug.
Incremental migration of existing codebases, file by file, tightening compiler settings as coverage grows.
Clients generated from OpenAPI or GraphQL schemas, so front ends always match the back end.
Zod schemas that validate input at runtime and provide static types from a single definition, used on client and server.
Well-typed packages that other teams can adopt without needing to read the source.
Our approach
How we keep TypeScript work tested, fast, secure and easy to release.
Strict mode and noUncheckedIndexedAccess for new code, with any exceptions documented rather than scattered.
Types stop at the network boundary, so every external input is validated with a schema before it is trusted.
Type checks run in CI alongside unit and end-to-end tests. Types reduce the tests you need, but don’t replace them.
Clear module boundaries, discriminated unions for state and generated types instead of hand-written duplicates.
Libraries, services and tools we commonly pair with TypeScript.

Usually, if the codebase is still actively developed. Migration can be gradual, starting with the most frequently changed files, so it never blocks feature work.
Slightly at first, while types are written. On any project that lives longer than a few months, it pays that time back through fewer bugs, faster refactoring and better editor support.
No. Types are removed during the build, so the code that runs is ordinary JavaScript.
