Why choose an expert TypeScript development firm
We have shipped 200+ TypeScript products with measurable results.
TypeScript eliminates entire categories of bugs. Our codebases have 40% fewer runtime errors than JavaScript equivalents.
With strict TypeScript configurations and exhaustive testing, we deliver software that stays stable under load. Clients see 99.9% uptime in production.
Generic dev shop vs expert TypeScript firm
Most agencies treat TypeScript as a flavor. We treat it as the foundation.
Generic shops often write JavaScript and add types as an afterthought. This leads to type conflicts, slow compile times, and brittle code.
IRPR engineers design type systems upfront. We use branded types, discriminated unions, and exhaustive switch statements so invalid states are impossible to represent.
- Types added after code is written
- No corporate coding standards
- No CI/CD type checking
- No automated refactoring support
- Slow compile times due to loose types
- No comprehensive linting
- Type-first design from day one
- Strict tsconfig with noUncheckedIndexedAccess
- TypeScript-ESLint with 50+ rules enforced
- Husky hooks block bad types pre-commit
- Incremental builds under 5 seconds
- Full type coverage in code reviews
Our TypeScript project process
Phase-based delivery with fixed pricing and no surprises.
We start with a 2-week Roadmap phase where we write architecture docs, define the type system, and give you a fixed price. Then we build in 2-week sprints with continuous delivery.
You see working software every 14 days. By week 12, you have a production-ready application with full test coverage and deployment pipelines.
What ships with every TypeScript project
Everything you need to run, maintain, and extend your application.
Full TypeScript source code with strict mode enabled. Every function has explicit return types. No any or unknown unless absolutely necessary.
Deployment pipeline with automated type checking, testing, and linting. We use GitHub Actions, Docker, and Terraform for infrastructure.
- Source code in your GitHub repository with full commit history
- CI/CD pipeline with TypeScript type checking on every push
- Pre-configured ESLint and Prettier configs
- Unit tests with Jest (80%+ coverage)
- End-to-end tests with Playwright
- API documentation generated from TypeScript types (Typedoc)
- Docker Compose setup for local development
- Deployment scripts for AWS (ECR, ECS, or Lambda)
- Monitoring setup (Sentry, DataDog)
- Readme with setup instructions and architecture diagram
What we ship in this practice.
Multi-tenant SaaS platform
A fintech startup needed a compliance-ready platform. We built a multi-tenant architecture with Stripe Billing and SOC 2 compliant logging. The client launched 6 weeks earlier than planned. Tech stack: Next.js, Prisma, PostgreSQL, Stripe.
Real-time collaboration app
A remote team tool required live sync across 1000+ users. We used WebSockets and CRDTs in TypeScript. Latency dropped to under 200ms. Tech stack: React, NestJS, Redis, WebSocket.
Ecommerce checkout system
A D2C brand needed PCI-DSS compliant checkout. We built a headless checkout with Stripe Elements and TypeScript validations. Cart abandonment fell by 22%. Tech stack: Next.js, Stripe, TypeScript, AWS.
Healthcare patient portal
A digital health company required HIPAA-compliant data handling. We used TypeScript with Zod for runtime validation and AWS Cognito for auth. Audit logging captured every access. Tech stack: React, Node.js, DynamoDB, Cognito.
Logistics inventory tracker
A manufacturing firm needed real-time inventory visibility across 5 warehouses. We built a TypeScript backend with Kafka for event streaming. Inventory discrepancies dropped to 0.5%. Tech stack: NestJS, Kafka, PostgreSQL, Grafana.
EdTech assessment engine
An online learning platform required auto-grading for 50,000 students. We built a TypeScript grading engine with plugin architecture. Grading time reduced from 3 hours to 15 minutes. Tech stack: Node.js, TypeScript, MongoDB, Redis.
Why teams hire us.
Senior TypeScript engineers only
IRPR hires only senior engineers with 8+ years of experience. Every team member has contributed to open-source TypeScript projects and passed our 4-hour coding assessment.
Fixed price, not hourly
We give you a fixed price after the 2-week Roadmap phase. No hourly billing means no surprise invoices or scope creep charges.
Full code ownership
You own every line of code from day one. We hand over the full GitHub repository, CI/CD pipeline, and infrastructure scripts at the end of each milestone.
Type-first architecture
We design the type system before writing a single line of business logic. This catches 90% of potential runtime errors at compile time and makes refactoring safe.
12-week MVP guarantee
Every project ships a fully tested MVP within 12 weeks. For larger scopes, we split into 8-12 week phases with working software after each one.
Compliance-ready from day one
We build SOC 2, HIPAA, and PCI-DSS compliance into the architecture from the start. No retrofitting audits or security patches after launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
