TypeScript Development Company Strict Mode & Type-Safe. Build Your Typed Platform. Then Your Mobile App.
Partner with a typescript development company that builds type-safe web applications, enterprise platforms, and JavaScript to TypeScript migrations — with strict mode enabled from sprint one, zero compiler errors at handover, and typed API contracts that power Flutter iOS and Android mobile apps on the same backend. Fixed price. Direct TypeScript engineer access. Our AI-powered development pipeline builds typed AI service layers into every TypeScript platform that needs them. Trusted by clients across USA, UK, Canada and India.
A TypeScript Development Company That Ships Zero-Error Typed Codebases — Not TypeScript in Name Only
Many TypeScript projects are TypeScript in syntax only — allowJs enabled, strict mode off, noImplicitAny disabled, and any types scattered through the codebase wherever a type was too difficult to define. These projects get the verbosity of TypeScript without its compile-time guarantees. Runtime type errors still reach production. The team gains no confidence refactoring. The type annotations become noise.
We build TypeScript platforms with strict mode enabled from sprint one — strictNullChecks, noImplicitAny, strictFunctionTypes, and useUnknownInCatchVariables all on. Type coverage is a metric reported at every sprint. At handover, you receive a codebase with zero TypeScript compiler errors in strict mode, typed API contracts shared between frontend and backend, and typed domain models that make your codebase safe to refactor. Our mobile app development team uses your TypeScript API contracts as the integration foundation for the Flutter iOS and Android app — reducing mobile API bugs to near zero. Our AI-powered development pipeline builds typed AI service layers — typed request payloads, typed streaming handlers, typed error unions.
Every TypeScript project we deliver uses TypeScript 5 with strict mode, shared type packages for API contracts, Zod for runtime type validation at API boundaries, Jest with typed test utilities, and ESLint with TypeScript-aware rules. For web projects: React 18 or Next.js 15 with TypeScript. For backends: Node.js, Express, or NestJS with full TypeScript strict mode. We have shipped a live TypeScript production platform — Casavera (casavera.uk) — with strict TypeScript throughout: typed Prisma ORM, typed API routes, typed component props.
AZRIVA is an Ahmedabad-based TypeScript development team working IST with daily overlap into UK mornings and USA afternoons. Every TypeScript project is fixed price — strict mode configuration, API contract design, application development, test coverage, and deployment — scoped completely before development begins. A mutual NDA is signed before any project discussion. Full source code and type declarations transfer to you at handover. Clients across USA, UK, Canada and India trust us with TypeScript platform builds and JavaScript to TypeScript migrations. Get a fixed-price TypeScript quote within 48 hours.

What Our We Deliver Builds for You
End-to-end TypeScript development — strict mode web platforms, JavaScript migrations, enterprise architecture, and typed AI service layers. Fixed price. Zero compiler errors at handover.
TypeScript Development Tools We Work With
Every TypeScript project is built with strict mode from sprint one — TypeScript 5, Zod for runtime validation, Jest with typed utilities, and ESLint with TypeScript-aware rules. Zero compiler errors as a contractual deliverable at handover.
Real TypeScript Challenges.
Every project carries risks — poor UX, missed deadlines, underperforming results. Here is how we eliminate each one.
How We Deliver TypeScript Projects
A six-stage TypeScript development process — every sprint delivers a fully typed, zero-error build with a type coverage report. The same type-safe discipline whether building a TypeScript web platform or extending it to a <a href="/mobile-app-development-company-india/" class="content-link">Flutter mobile app</a> using your typed API contracts as the integration foundation.
Discovery & Type Architecture
We begin with a structured discovery call to understand your TypeScript project — application scope, existing JavaScript state if migrating, strict mode targets, and deployment architecture. We design the type system architecture — shared type packages, API contract interfaces, domain model types — before any TypeScript code is written.
Type Contract Design & UI Sign-Off
All API type contracts are documented — typed request interfaces, typed response shapes, typed error unions, typed configuration objects. For web applications, UI screens are designed and approved in Figma. No development begins until both type contracts and UI designs are signed off.
Fixed-Price Proposal
A fixed-price proposal covers the complete TypeScript scope — application architecture, type system design, API contracts, test coverage targets, build configuration, CI pipeline, and deployment. One price. Strict mode enabled by default. Zero TypeScript errors as a contractual deliverable.
TypeScript Strict Mode Development
Development runs in two-week sprints with strict TypeScript enabled from sprint one. Every sprint deliverable reports type coverage percentage. You receive a fully typed, staged build with zero compiler errors at the end of every sprint — type safety as a measurable, reported quality metric throughout.
QA — Type Coverage and Test Suite
Every TypeScript build passes strict compiler checks with zero errors, Jest unit tests with typed test utilities, integration tests against typed API contracts, and end-to-end tests with Playwright or Cypress. Type coverage report included in every sprint delivery. No build ships with compiler warnings suppressed.
Deployment & Mobile Extension
We manage TypeScript compilation to optimised JavaScript with source maps, type declaration files published for shared packages, and deployment to your chosen infrastructure. Post-launch support included for 60 days. When your typed platform needs a mobile app — Flutter connects to your TypeScript API contracts as the integration foundation.
Industry-Specific TypeScript Development
We deliver AI solutions for TypeScript applications across frontend, backend, and full-stack for the industries where strict type safety, long-term maintainability, and zero-tolerance for runtime errors protect critical business operations — fintech, healthcare, and logistics.
What Sets Our TypeScript Development Apart
Businesses choose us because of how we work — not just what we build.
for Enterprise Platforms vs JavaScript vs Flow — Which Is Right for You?
Choosing the right type system for your enterprise web platform. How TypeScript compares against plain JavaScript and Facebook's Flow across the criteria that matter most for long-term codebase maintainability and team scalability.

Every TypeScript project at AZRIVA is fixed price — including strict mode configuration, type coverage targets, and zero compiler errors at handover. Pricing depends on scope, codebase size for migrations, and platform complexity.
All pricing is fixed — the number in your proposal is the number on your invoice. Zero TypeScript compiler errors and strict mode enabled are included in every tier, not premium add-ons. Clients who extend their TypeScript platform to Flutter mobile app development receive the same fixed-price model. VAT/GST applicable for Indian clients.
How We Engage With Businesses
Whether you need a fixed-price TypeScript platform, a dedicated team for a JavaScript to TypeScript migration, or a typed AI-first architecture that powers both your web platform and Flutter mobile app from one typed backend.
Complete TypeScript scope defined and priced before development begins. Strict mode, shared API types, full test coverage, and zero compiler errors — all contractual deliverables at a fixed price. No hourly billing. No type debt at handover.
