Plain JavaScript works fine until three engineers are editing the same module and nobody's sure what shape the data actually is. We write TypeScript by default across frontend and backend — catching mismatches at compile time instead of in production, and leaving you a codebase that's easier to scale and easier to hand off.
Untyped JavaScript is fast to start and expensive to maintain. Types pay off the moment a second engineer touches the code.
Type mismatches, undefined values, and wrong API shapes get caught while you're writing the code — not after a customer hits them.
Rename a field or change a function signature and the compiler shows you every place that breaks, instead of finding out at runtime.
Types are documentation that can't go stale — new team members read the interfaces instead of guessing from usage.
We don't ship `any` as a shortcut. Strict compiler settings from day one mean the type system is actually doing its job.
One source of truth for request/response shapes, so the API and the client can't silently drift apart.
Typed code, documented interfaces, and clean commit history so your in-house team or the next vendor isn't reverse-engineering intent.
Scoped to what your codebase needs — from a full build to an incremental migration.
New web apps and APIs built typed from the first commit, frontend and backend.
Incremental conversion of an existing codebase, module by module, without freezing feature work.
Typed, reusable component systems with props and state modeled explicitly, not inferred loosely.
Node.js APIs and services with typed request/response contracts shared with the frontend.
tsconfig, linting, and shared type packages set up so strictness doesn't slow the team down.
Reviewing an existing setup — strict mode gaps, `any` usage, config issues — and a plan to fix it.
At small scale the difference is minor. Past a handful of engineers or a few months of iteration, TypeScript catches the bugs that plain JavaScript only surfaces in production — mismatched API shapes, wrong assumptions about optional fields, broken refactors nobody noticed.
Yes. We migrate incrementally — enabling TypeScript alongside existing JavaScript and converting module by module — so your team keeps shipping features instead of freezing for a rewrite.
It adds a small amount of upfront thinking about data shapes, but it removes the time spent debugging runtime errors that types would have caught. Most teams net faster after the first few weeks.
Yes. We enable strict compiler settings from the start of a project rather than adding them later — retrofitting strict mode onto a loosely typed codebase is far more expensive than starting with it.
