TypeScript Development Services for Code You Can Change Safely

Netofficials provides TypeScript development services for web products, portals and APIs that your team can keep extending with confidence. Typed code catches many frontend-to-API mismatches before release. One cross-functional team works from a written discovery scope, and you review progress at the end of every sprint. Send a brief to start.

Delivery
One cross-functional team covers front-end, back-end, QA and DevOps, so your TypeScript build runs from a single shared plan.
Contact
A named delivery lead owns day-to-day progress and keeps you informed, while a technical architect is accountable for code quality standards.
Ownership
The contract confirms IP assignment before the build begins, so your TypeScript codebase is yours from the first commit.
Reviews
Each sprint ends with a client-facing review, working from a written discovery scope you have already approved.
What you get

What we build in TypeScript

Typed web applications

We build customer portals, dashboards and SaaS front ends in TypeScript, where the compiler flags a mismatched field or prop before it reaches a browser. You get a codebase that is safer to change as features are added, with fewer regressions from small edits.

Typed APIs and shared contracts

We build Node.js back ends in TypeScript and share types with the front end, so the interface and the API agree on the same data shapes. Integration surprises surface during development instead of in testing, and your team can read the contract rather than guess it.

JavaScript migration and takeover

If your JavaScript codebase has become hard to change, we move it to TypeScript in stages while the product keeps running. Our technical architect sets the typing standards, and you get code your own engineers can pick up and extend.

Fit guidance

Is TypeScript the right fit for your build?

ConsiderationTypeScript suits best whenWe would suggest another approach when
Codebase sizeThe product will grow over several releases and more than one developer will change it, so typed interfaces keep changes safe.The build is a short-lived prototype or a one-off script; after scoping, we will say if plain JavaScript is the leaner option.
Team and handoverYour own engineers will take the code over and need types to act as living documentation of how the frontend, API and data models connect.Your team already maintains a stable codebase in another language; after scoping, we will recommend staying in that stack rather than adding a second one.
Frontend and APIWeb applications and APIs that share data models, such as a React or Next.js interface on a Node.js backend, where a changed API contract shows up as a type error during development.The work is a short-lived prototype, or the core logic sits in a backend language such as Python with little shared code. We will recommend the lighter or better-matched approach after scoping.
How an engagement runs

From written scope to TypeScript release

  1. Discovery

    We write down your users, existing APIs and first-release scope, and decide where TypeScript types should sit across the frontend, API and shared code.

    You receive
    • Written discovery scope for the first release
    • Open questions on existing code and APIs
    • Initial estimate with stated assumptions

    You sign off the written scope before design begins

  2. Design

    Our technical architect sets out the data models, API contracts and component structure, and you review them alongside the interface designs before development starts.

    You receive
    • User flows for each key journey
    • Interface designs to review before the build
    • Architecture notes on shared types and API contracts

    You approve the designs and architecture before any code is written

  3. Build

    Our cross-functional team builds in Agile sprints, with strict typing and code review as standard, and you see working staging builds at every sprint review.

    You receive
    • Staging builds to try at each sprint
    • Staging builds you can click through after each sprint
    • Sprint review notes with decisions and the next sprint's priorities

    You review working software at the end of every sprint

  4. QA

    Our QA engineers test the critical user journeys against the acceptance criteria you agreed, and log every issue for you to track before release.

    You receive
    • Acceptance checklist tied to the criteria agreed in discovery
    • QA report covering type checks and tests on critical journeys
    • Issue log showing each defect's status and fix

    You sign off the TypeScript build against the written acceptance criteria.

  5. Release

    We deploy to production, then hand over documentation and deployment access so your team can run and extend the typed codebase.

    You receive
    • Production release deployed with the agreed deployment access
    • Documentation your team can use to maintain the TypeScript code
    • Handover of repositories, environments and deployment access

    Your team can operate the release without us

Connected architecture

A TypeScript stack where every layer is agreed

LayerTypical choicesWhat we settle with you
InterfaceTypeScript with React, or React Native when the product also needs a mobile appStrictness of the type configuration, shared component patterns and how much of the existing JavaScript to migrate
RenderingNext.js for pages that need server rendering, or a client-side React application for logged-in toolsWhether public pages need indexing, how hosting is set up and what performance the product needs
API and dataNode.js with TypeScript, Python services, PostgreSQLHow typed API contracts match your existing services, and who owns each one
QualityType checks in the build, plus Playwright end-to-end tests and agreed test layersCritical user journeys, release risks and the acceptance criteria you sign off

Delivery & QA

Quality built into every sprint

  • Typed components and APIs reviewed by the technical architect against agreed code quality standards
  • Acceptance criteria written at discovery, so testing checks the journeys that matter to your users
  • A client-facing review at the end of each sprint, with QA results shown on a staging build
Engagement models

Choose how we build your TypeScript product

Project delivery

A fixed-price TypeScript build, such as a web application, portal or JavaScript migration, with a defined first release and a written discovery scope behind it.

  • Fixed price set against the written discovery scope, so the first release has clear boundaries
  • Acceptance criteria, milestones and test coverage for key user journeys agreed before the build starts
  • Sprint-end reviews of working builds, with a change request for anything outside the agreed scope

Dedicated team

A dedicated India-based team that keeps extending your TypeScript product sprint after sprint, suited to a roadmap that will keep growing after launch.

  • Frontend, backend and QA engineers chosen for your TypeScript stack and the way your API and interface connect
  • Dedicated India-based team with TypeScript, React and Node.js skills matched to your product
  • Source code and IP ownership assigned to you in the contract before the build begins

Staff augmentation

Individual TypeScript engineers who work in your repositories, tools and code review process, suited to teams that already have technical leadership and need more capacity.

  • Individual TypeScript engineers who join your repository, code review and release process
  • Work runs in your tracker and CI, under your own conventions for types and linting
  • Communication window and update cadence agreed with you before the first commit
Before you enquire

TypeScript project questions, answered

What drives the cost and timeline of a TypeScript project?

Five things drive the cost and timeline: the size of the first release, the number of integrations with existing APIs and services, whether you are building new or migrating JavaScript, how much interface design is needed, and the team size you choose. We capture these in a written discovery scope with an initial estimate before development starts, so you can see the assumptions behind the numbers. You can then pick fixed-price project delivery, a dedicated team or staff augmentation. Send a short brief and we will return questions and a proposed scope.

Who owns the TypeScript code and IP?

You do. Netofficials confirms IP assignment in the contract before any TypeScript is written, so the source code you pay for is yours from the start of the build. At release we hand over documentation and deployment access, so your own engineers or another vendor can pick the project up without depending on us.

Can you migrate our JavaScript code or work with our team across time zones?

Yes. We can add TypeScript to an existing JavaScript codebase in stages, or build a new typed application alongside your current systems, working inside your repositories and tools. A named delivery lead is your single point of contact. We agree the communication window, meeting schedule and update cadence before work begins, so time zone differences are settled up front. If a full rewrite would not pay off, we will say so after scoping and recommend a lighter route.

Send your brief for a TypeScript build

Tell us what you are building, or which JavaScript codebase you want to move to TypeScript. We reply with a written discovery scope, the team we would put on it and the questions we need answered before an estimate. If another approach would serve you better, we will say so after scoping. You then work with one named delivery lead, and IP assignment is confirmed in the contract before the build starts.
