Dedicated Resource · TypeScript
A dedicated TypeScript developer from Typescriptaz works in your repo, not in a slide-deck pool. We provide senior TypeScript developers who treat types as a product tool: clean domain models, strict compiler flags, no any graveyards. Permanently employed, fluent in English and German, and dedicated to your backlog—individually or as a full team.
Use
From monorepos to shared SDKs: in many teams, TypeScript is the glue between frontend, backend, and mobile. That's exactly where your developer steps in. They clean up types, draw clear boundaries between packages, and ensure refactorings show up in the editor—not only in production—whether the code is in a React frontend or a NestJS API Lives.
Since TypeScript’s native compiler runs in Go, builds and type checks are many times faster. To benefit, you need a clean setup: Project References, clear tsconfig inheritance, and tools that match the new version. We plan the migration so your delivery continues.
For you as the IT lead, this mainly means fewer surprises. A strictly typed project surfaces errors where they’re cheap to fix—in the editor and in CI. It also reduces risk when people change roles, because the code itself documents where data flows.
Typical mandates: SaaS core systems, B2B portals, design systems, platform teams.
Tools: TypeScript, Node.js, React, NestJS, tRPC, Effect, Prisma

Quick explanation
TypeScript is a Microsoft‑developed extension of JavaScript that adds static types. The code is checked before execution and then compiled to plain JavaScript — so it runs anywhere JavaScript runs: in the browser, on the server with Node.js, and in mobile apps. For businesses, TypeScript is mainly a tool for quality and scalability: large codebases remain understandable, errors surface earlier, and multiple teams can safely work on the same code. With version 7, the language gained a native compiler that significantly speeds up builds.
Dedicated Team
Expertise
Seniority isn’t shown on the resume but in code review. Our team looks for it with TypeScript.
01
A senior uses generics, conditional types, and discriminated unions where they prevent errors—not to show off. The result is types your team understands and can maintain, even when the senior isn't in the room.
02
Project references, incremental builds, pnpm workspaces, Nx or Turborepo: anyone familiar with large codebases knows where build time is lost. With TypeScript comes a native compiler that changes the pace—and a few tools that still need to catch up.
03
Types only apply to your own code. At APIs, forms, and queues, you need runtime validation, for example, with Zod or Valibot. An experienced developer enforces this line consistently so unchecked data never lands in the middle of the system.
04
From JavaScript to TypeScript, from loose to strict mode, from version 5 to 7: a senior plans such changes in stages with measurable interim goals, so features keep going live.
Typical situations
01
Lots of any, little confidence in refactoring? We introduce Strict Mode module by module while your team continues delivering features.
02
If web, backend and app use the same models, they belong in a single package with versioned types—rather than three copies that drift apart.
03
Public types are a promise to your customers. We ensure breaking changes are caught before anyone installs them.
Risk under control
TypeScript projects rarely fail because of the language, but because of half‑hearted migrations and types nobody understands anymore. We specifically mitigate these three risks for you:
A project with half‑hearted strictness is often worse than one without. That's why we define up front which modules become strict in what order and measure progress—e.g., by the number of remaining any occurrences. That way you always know where you stand.
Clever type constructs that only one person understands are a single point of failure. Our senior engineers document core types, explain them in reviews, and keep them as simple as possible. The knowledge stays with the team, not in one person’s head.
With TypeScript, the compiler changes fundamentally. Linters, test runners, and build plugins that rely on the old API need to be checked. We test the migration first on a branch and switch only when your CI is green across the board.
A monorepo without clear boundaries slows down and becomes harder to understand with each package. We define dependency rules between packages, measure build times, and separate what doesn't belong together—so the repo can scale with the team.
Transparency
Business case
A dedicated TypeScript developer pays off mainly through fewer bugs and faster onboarding. Every error the compiler catches does not become a support ticket. New team members understand typed code faster because interfaces and data models are described in the code itself. And with shorter build times, you win back minutes for your team every day that add up to real weeks over months. For decision‑makers that means: more predictable releases, lower follow‑up costs, and less dependence on individual knowledge holders.
The first two weeks
Analysis, first delivery, clear plan. Read about how we work in general at How we work.
01
Where are any, ts‑ignore, and unsafe casts hiding? The inventory shows where cleanup yields the most benefit.
02
At the same time, the first tasks from your backlog go into review—no waiting for the perfect plan.
03
After two weeks, a proposal is on the table: what becomes strict first, what can wait, and how you measure progress.
After kickoff
How a typical engagement develops after the first two weeks—aligned with your backlog.
01
Type inventory, build analysis, and the first features from the backlog. At the end of the month there’s a prioritized roadmap for Strict Mode and package structure.
02
The most important shared packages are strictly typed, runtime validation is introduced at system boundaries, and build times are measured regularly.
03
More modules will follow, the switch to TypeScript will be prepared or implemented, and the team will work according to documented conventions.
Example scenario
A product team runs a web app, API, and admin interface in a monorepo. Types have grown over the years, builds take a long time, and refactoring regularly breaks things. A senior TypeScript developer starts with a type inventory and a plan that addresses shared packages first.
After a few sprints, core packages run in Strict Mode, API types are generated from a single source, and new features require fewer back-and-forths between frontend and backend. If demand grows, an Intermediate joins—the dedicated TypeScript team forms step by step.
For management, the bottom line is the result: fewer support bugs, shorter build times, and new developers who are productive after days instead of weeks.
Collaboration
For ongoing product development, the monthly plan is standard: a senior developer working 40 hours per week who owns both architecture and features. For well‑defined initiatives—such as migrating a single package to Strict Mode or switching to TypeScript—an hour bundle is often sufficient.
Unsure how large the effort is? Start with the discovery package: a code review, onboarding, and a sprint quickly show where your codebase stands and what a realistic plan is.

Straight talk
TypeScript is not the right choice for every project. For small scripts, short‑lived prototypes, or pages with little logic, the overhead of types and a build step can outweigh the benefit. A team facing an imminent deadline should not start a large migration. In those cases, we’ll tell you — and recommend starting new modules with types and migrating the rest later.
For IT decision-makers
Can the person explain when they deliberately avoid complex types?
Has she already supported a migration to Strict Mode in a large codebase?
Do you validate data at system boundaries at runtime — or do you rely only on types?
Do they know your build setup with monorepo, bundler, and CI — and its bottlenecks?
Do you record decisions so your team can understand them without you?
Glossary
A collection of compiler options that forbid unsafe patterns, such as implicit any or missing null checks.
Splitting large codebases into subprojects that are built independently and incrementally.
A type that distinguishes multiple variants via a common field — ideal for states and events.
Validation of external data at runtime, for example with Zod or Valibot, because types don’t exist at runtime.
Often a good fit
Frequently asked questions
For most projects, yes—especially large monorepos with long type‑check times. Beforehand, we check which tools still rely on the old compiler API—a stable programmatic API is only planned for a later 7.x release.
Yes. With allowJs and checkJs you can migrate an existing codebase file by file. New modules are created directly in TypeScript; older ones are converted when they're touched.
Yes—if that's what you want. Our TypeScript senior engineers know Node.js and NestJS and carry types from the database schema all the way to the UI. For pure backend work you can also book a dedicated Node.js developer.
The correct term is “dediziert”—from English “dedicated,” meaning devoted to a task. “Dezidiert” means “decided.” Someone searching for a “dezidierter TypeScript developer” almost always means the same thing: a person assigned permanently to your project who doesn’t work for other clients on the side.
Yes—with one difference: we don’t deliver a project from a black box; we provide senior developers or an entire team that works directly in your repo. That makes us more of an outsourcing partner than a traditional agency. TypeScript agency Read on the homepage.
In Vienna, Klagenfurt, Graz, and Karlsruhe — all in Central European Time and fluent in English and German. For companies in Germany and Switzerland, this is Software nearshoring from Austria No time difference.
In published benchmarks, full builds are about eight to twelve times faster than with TypeScript. How much of that you realize depends on the project—so we measure before and after the migration.
Usually not. The language fits into existing pipelines with Vite, esbuild, webpack, or tsc. We add type-check steps in CI and optimize where it’s needed.
With clear metrics: remaining 'any' occurrences, proportion of strict modules, production errors, and build times. You receive these metrics regularly so progress isn’t left to guesswork.
Bottom line
A dedicated TypeScript developer brings order to growing codebases, makes bugs visible early, and helps your team deliver faster and with more confidence. You get senior know-how, transparent progress, and the option to scale into a dedicated TypeScript team—without recruiting risk and with full ownership of the code.
