Custom TypeScript Development Services
You’ve probably used products built with our TypeScript expertise.
Gensoft has delivered hundreds of TypeScript projects where strong typing turned chaotic codebases into reliable, team-friendly platforms. We help organizations scale JavaScript applications safely, improve developer velocity, and ship features with confidence.
Enterprise Web Applications
We build large-scale web platforms using TypeScript with React or Angular. Strict typing across the stack catches errors early, makes onboarding new developers faster, and keeps complex business logic maintainable as the application evolves.
Full-Stack Solutions with Next.js & NestJS
End-to-end TypeScript means shared types between frontend and backend, better tooling, and fewer integration surprises. We deliver modern full-stack apps that are easy to test, deploy, and scale.
API-First Backends and Microservices
Using NestJS or standalone Node with TypeScript, we create well-typed REST and GraphQL APIs that are self-documenting and resilient. Contract-first development reduces miscommunication between teams.
JavaScript to TypeScript Migrations
We help teams adopt TypeScript incrementally without stopping feature work. Through careful strategy, type declaration files, and gradual strictness increases, we turn legacy JS codebases into robust, type-safe platforms.
Design Systems and Shared Component Libraries
TypeScript shines when building reusable UI libraries. We create strongly typed component kits with Storybook, theming, and clear props interfaces that multiple teams can adopt safely and consistently.
Internal Tools, Dashboards, and Admin Platforms
Complex forms, data-heavy tables, real-time updates, and role-based UIs benefit enormously from TypeScript. We deliver internal platforms that are a pleasure to use and maintain.
Safety and scale without slowing down
TypeScript brings the confidence of static types to the flexibility of JavaScript, making it ideal for ambitious projects and growing teams.
Early Error Detection
Types catch mistakes at compile time instead of in production. Refactoring becomes safer and faster, especially in large codebases with many contributors.
Better Collaboration
Explicit interfaces and contracts make it easier for teams to work together. New developers understand the shape of data and APIs without guessing.
Superior Tooling
Autocompletion, inline documentation, and refactoring tools in modern editors dramatically improve developer productivity and reduce context switching.
Long-Term Maintainability
As applications grow, TypeScript helps keep the codebase understandable and adaptable, reducing the cost of change over years of evolution.

TypeScript quality practices that matter
We treat types as a first-class part of the architecture, not just an add-on to JavaScript.
Strict Typing from the Start
We enable the strictest TypeScript configuration and use advanced patterns like branded types, template literal types, and conditional types to model business logic accurately.
- noImplicitAny, strictNullChecks, exactOptionalPropertyTypes
- Shared type packages between frontend and backend
- Runtime validation with Zod where needed
- Exhaustive checking in switch statements
Thoughtful API & Contract Design
Types define the contract between systems. We design clear, versioned interfaces that make integration predictable and errors obvious.
- Code-first GraphQL or tRPC schemas
- DTOs and validation at boundaries
- Generated clients for type-safe consumption
- Backward-compatible evolution strategies
Comprehensive Testing & Tooling
Types reduce the need for some defensive tests, but we still verify behavior thoroughly with modern tooling.
- Type tests with tsd or expect-type
- Unit and integration tests with Vitest
- E2E with Playwright
- ESLint rules for type safety (typescript-eslint)
Developer Experience & Onboarding
Great types pay dividends in how quickly new team members become productive and how safely the codebase can evolve.
- Self-documenting code through types
- Monorepo setups with shared configs
- Storybook with typed controls
- Clear error messages and documentation
