TypeScript Development for End-to-End Type Safety
Strict Mode, Codegen, tRPC and Zod by Default
Work with senior TypeScript developers who ship TypeScript to production every week. From greenfield Next.js, NestJS, and Bun apps to JavaScript to TypeScript migrations, monorepo setups with Turborepo or Nx, design system libraries published as typed npm packages, OpenAPI codegen to typed clients, and SDKs with strict semver. Every repo ships with strict mode and noUncheckedIndexedAccess on.
How Much Does TypeScript Development Cost?
Honest USD Rate Bands From an Indian Senior Team
Most TypeScript MVPs we ship come in between $8K and $18K. Full-stack type-safe apps with tRPC, Prisma, Zod, and Auth.js usually fall between $25K and $55K. Enterprise monorepos with Turborepo or Nx, shared types, and design systems start near $75K. Prefer a senior TypeScript developer on your team instead? From $1,800 per month, first week on us.

What We Build
What can we build with TypeScript?
Six categories of TypeScript work, from full-stack apps to monorepos and SDK packages.
Reference Architecture
Which architecture do we use for TypeScript development?
Six layers we wire together on greenfield TypeScript projects. Type-safe end to end, no any escapes, codegen-first.
tsconfig
strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes, isolatedModules, project references for monorepos. tsc --noEmit gates merge in CI.
Schema
Zod or Valibot for runtime schemas, inferred TS types from one source. Codegen from OpenAPI or GraphQL produces the rest. One source of truth, no drift.
Data
Prisma or Drizzle generates types from the schema. Database to TS types automatically. Migrations versioned, reversible, peer reviewed.
API
tRPC inside internal apps for end-to-end types without codegen. Hono or Fastify with Zod for external APIs. OpenAPI 3 emitted, typed clients generated automatically.
Security
Auth.js or Lucia or Clerk for sessions, Zod-validated input on every boundary, RBAC at the service layer, exhaustive checks via switch on discriminated unions.
CI / Release
Turborepo or Nx for caching, Vitest, Playwright, ESLint with type-aware rules, Renovate for deps, semantic-release for SDKs, Sentry on release with source maps.
Every layer documented in your repository on day one
