TypeScript DevelopmentTypeScript Development That Eliminates Entire Categories of Bugs
We write type-safe code across your entire stack — from frontend components to backend services to shared libraries. Fewer runtime errors, better tooling, and codebases that document themselves.

What We Build with TypeScript
Real projects we deliver for clients every month.
Type-Safe API Layers
End-to-end typed APIs using tRPC, Zod validation, and generated OpenAPI specs where the compiler catches contract violations before they reach your users.
Shared Library Packages
Internal npm packages with precise type exports, proper declaration files, and semantic versioning that multiple teams consume with full IntelliSense support.
Complex Business Logic Engines
Pricing calculators, workflow engines, and rule systems where discriminated unions and exhaustive pattern matching guarantee every edge case is handled at compile time.
Monorepo Architectures
Turborepo and Nx workspaces with shared TypeScript configurations, cross-project type checking, and incremental builds that keep large codebases fast and consistent.
JavaScript-to-TypeScript Migrations
Incremental conversions of existing JavaScript codebases with strict null checks, proper error boundaries, and zero downtime — file by file, module by module.
Why TypeScript?
The technical advantages that make TypeScript the right choice.
Catch bugs at compile time, not in production
TypeScript's type system eliminates null reference errors, property typos, and mismatched function signatures before code ever runs. Your monitoring dashboards stay quiet.
Self-documenting code that ages well
Types serve as living documentation. Six months from now, a developer opening your codebase can understand data shapes, function contracts, and component props without reading a single comment.
Refactoring without fear
Rename a field, change a return type, restructure an interface — the compiler instantly shows every file that needs updating. Large-scale refactors that would take days in JavaScript take hours in TypeScript.
The industry standard for serious JavaScript
Angular, Next.js, Deno, and SvelteKit are all built with TypeScript. Library authors publish type definitions by default. Choosing TypeScript means choosing the direction the entire ecosystem is heading.
How It Works
From request to delivery in four simple steps.
Share your TypeScript needs
Tell us what you're building or migrating. We assess your current codebase, tsconfig settings, and architecture to scope the work accurately.
We define types and build features
Our developers create precise type definitions, implement features with strict compiler settings, and ensure types flow cleanly across module boundaries.
Review the code and the types
You review working code along with the type contracts. We walk through complex generics or utility types so your team understands and can extend them confidently.
Merge and continue
Approved code merges into your repository with zero type errors. We move to your next request while your codebase grows safer with every commit.
One plan. Unlimited everything.
One simple plan. No tiers, no hidden fees, no long-term contracts.

Frequently Asked Questions
Everything you need to know.
Yes, and we do it incrementally. We start with strict tsconfig settings, convert files one module at a time, and add proper types progressively. Your app keeps running in production throughout the entire migration.
Always. We enable strict, noUncheckedIndexedAccess, and exactOptionalPropertyTypes. We avoid 'any' types and use proper generics instead. The stricter the compiler, the fewer the bugs.
We check DefinitelyTyped first. If type definitions don't exist, we write custom declaration files that accurately describe the library's API. No 'any' escape hatches.
Absolutely. We configure Turborepo or Nx with shared tsconfig files, project references, composite builds, and proper dependency graphs so type checking stays fast as your repo grows.
We use Zod or Valibot to validate data at API boundaries, form inputs, and external integrations. Types and runtime schemas stay in sync through inference, so you never have to define a shape twice.
