One Language. Every Layer. AI-Assisted.
TypeScript Development Services
AI-augmented TypeScript development end to end: our engineers use strict types and shared contracts across web, mobile, and backend so whole bug classes disappear at compile time, with 60 days of support.

What our typeScript development services cover
Not just TypeScript as a linter for JavaScript, but a typed system applied with intent across the stack.
Full-stack typeScript products
Web front ends, API backends, and mobile clients sharing types through a monorepo, so a backend field rename fails the client build instead of Friday night's crash report.
- ✓Shared types and validation schemas
- ✓Turborepo or Nx monorepos
- ✓End-to-end type safety with tRPC
- ✓One CI pipeline for all targets
JavaScript to typeScript conversion
Untyped codebases migrated incrementally with allowJs and per-module strictness, so your product keeps shipping while the type safety catches up.
- ✓Incremental migration plans
- ✓Strict mode without the big bang
- ✓Typed API boundaries first
- ✓CI type-check gates
Typed API platforms
Backends where the contract is the code: OpenAPI-generated clients, runtime validation with Zod, and errors modelled as values rather than thrown surprises.
- ✓OpenAPI and tRPC contracts
- ✓Zod runtime validation
- ✓Discriminated union errors
- ✓Generated SDKs for every client
Design systems and libraries
Typed component libraries with strict props, discriminated variants, and generated documentation, so misusing a component is a build error, not a design review.
- ✓Strict component prop types
- ✓Variant-based APIs
- ✓Generated docs and types
- ✓Semver versioned packages
Tooling and build modernisation
Slow builds, broken sourcemaps, and mismatched configs across repos replaced with coherent toolchain choices and cached pipelines.
- ✓TSConfig strategy per repo
- ✓ESBuild, SWC, or tsx pipelines
- ✓Path aliases and project references
- ✓Cached, affected-only CI
Type-level architecture reviews
Audits of existing TypeScript codebases that find the any leaking, the unsafe casts, and the state modelled as strings, then fix the design, not just the annotations.
- ✓Strictness and any audits
- ✓Domain modelling with unions
- ✓Branded types for IDs and money
- ✓Refactoring roadmap
What every engagement includes
Every TypeScript project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped TypeScript roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All TypeScript source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and framework upgrades ship free for a full year after handover.
insight
Why typeScript changes the whole stack
TypeScript pays most when it spans layers: one language and one contract system across web, backend, and mobile removes the translation layer where integration bugs live. Teams that adopt it well report fewer production incidents per feature, and onboarding speeds up because the types document the domain.
See it applied per surface in our Next.js development services, Node.js development services, and React Native app development pages, or talk to our full-stack development team about one TypeScript codebase for everything.
The stack behind our typeScript work
Toolchain choices we make deliberately, per project.
Compiler discipline
Strict mode always, no unchecked indexed access surprises, and tsconfig strategy per repository so moving code between packages never weakens the guarantees.
Validation at the edges
Zod or Valibot schemas parsed at every system boundary and inferred into types, because the wire does not care about your compile-time confidence.
Monorepo tooling
Turborepo or Nx with project references, cached builds, and affected-only test runs, keeping large TypeScript estates fast enough that CI never becomes the bottleneck.
Backend runtimes
Node.js LTS as the default, Bun or edge runtimes where their trade-offs fit, with frameworks chosen for the workload rather than the README.
Testing and quality
Vitest for units, Playwright for end-to-end, type tests with expectTypeOf for critical contracts, and mutation testing on money paths where it pays.
AI-augmented review
AI tooling drafts types, tests, and refactors while senior engineers review every merge, and type coverage is tracked as a metric so it cannot silently rot.
How a typeScript project runs
Six stages with sign-off gates, designed around shared contracts.
- 01
Discovery
Surfaces, domains, and integration points mapped in a workshop, ending in a fixed written quote and a monorepo layout proposal with contract boundaries drawn.
✓ step 01 complete - 02
Contract design
Domain types, API schemas, and validation rules designed first and reviewed by every client team, so implementations can start against stable contracts.
✓ step 02 complete - 03
Foundation sprint
Monorepo, CI, shared packages, and environments scaffolded first. A walking skeleton proves the full type chain from database to UI in week one.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with live demos. Type-check, lint, and tests gate every merge, and type coverage is reported so quality cannot decay quietly.
✓ step 04 complete - 05
Hardening and launch
Load and integration testing against the contract suite, security review, performance budgets verified, and staged rollout with monitoring from the first deploy.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and architecture records plus typed contracts that make any future team productive fast.
✓ step 06 complete

Why teams choose our typeScript engineers
Type safety is a habit, and ours is enforced by pipelines rather than intentions.
Strict mode without excuses
Any and unchecked casts are debt we refuse to write, and type coverage is tracked so the codebase you inherit is as safe as the one we demoed.
AI-augmented delivery
AI tooling accelerates typing, testing, and refactoring across our TypeScript projects while senior engineers own every domain-modelling decision.
Contracts before code
We design the types and API schemas first, so parallel teams build against stability instead of discovering integration bugs in staging.
Monorepo fluency
Shared packages, cached builds, and affected-only pipelines are our default craft, not a configuration experiment on your billing hours.
Migration experience
We have converted large JavaScript estates to TypeScript incrementally without pausing product delivery, and we bring that playbook to yours.
Track record since 2010
9,000+ projects and 3,900+ published products across 25+ countries, with typed full-stack platforms at real scale among them.
