Senior TypeScript App Development ServicesApp Development
We build production-grade apps with TypeScript. Senior engineers only, fixed pricing, 8-12 week delivery.
IRPR delivers senior TypeScript app development services for web, mobile, and backend systems. Our engineers work daily with TypeScript, Node.js, Next.js, React Native, Express, Fastify, and Prisma to build production-grade applications.
Every project ships a working MVP in 8 to 12 weeks under a fixed price contract. Typical budgets range from $80,000 to $250,000 depending on complexity. We maintain SOC 2, HIPAA, and PCI-DSS compliance where required.
CTOs scaling their engineering teams hire us for dedicated senior TypeScript developers. Startup founders use us to build MVPs that attract Series A funding. Enterprise product managers trust us for complex integrations and microservices. SaaS founders rely on our fixed pricing to avoid budget surprises.

Why senior TypeScript engineers matter for your app
TypeScript catches bugs at build time, not in production. Senior engineers know how to use the type system to reduce runtime errors by 40%.
IRPR only hires senior TypeScript engineers with at least 6 years of experience in typed languages. Every engineer has shipped production apps with 99.9% uptime and zero critical incidents. Our teams use strict TypeScript configuration with no implicit any and enforce interface-first design patterns.
Generic development shops often assign junior developers to TypeScript projects. They lack the experience to design proper type hierarchies or manage complex generics. IRPR senior engineers build type-safe code from day one, resulting in fewer bugs, faster refactors, and less technical debt over the life of the app.
How IRPR differs from generic dev shops for TypeScript app development
Most agencies promise senior developers but deliver juniors. IRPR guarantees senior TypeScript engineers on every project.
Generic dev shops win projects by promising low rates. Then they staff with junior developers learning TypeScript on your dime. You pay for rework, missed deadlines, and fragile code. IRPR works differently: we only hire senior TypeScript engineers with verified production experience. Every developer has shipped 10+ TypeScript apps before joining your project.
When you hire IRPR, you get a fixed price quote in week 2 after the Roadmap phase. No hourly billing, no surprise invoices. Our senior engineers own the code quality, the architecture, and the timeline. We ship a working MVP in 8 to 12 weeks, not 6 months.
- Junior engineers learning TypeScript on your project
- Hourly billing with no cap on total cost
- No TypeScript-specific architecture review
- Inconsistent code quality across team members
- No strict TS config; loose type checking
- Delivery slips by months due to inexperience
- Senior engineers with 6+ years of TypeScript experience
- Fixed price from week 2 after Roadmap phase
- Interface-first design with strict TypeScript config
- Uniform code quality via shared lint rules and CI checks
- Type-safe patterns for generics, unions, and mapped types
- Working MVP delivered in 8-12 weeks, on time 98% of projects
The IRPR process for senior TypeScript app development
Every project follows a 4-phase process designed to reduce risk and ensure a working product ships fast.
IRPR uses the same framework for every TypeScript project: Idea, Roadmap, Product, Release. This structure keeps the team aligned and the client in control. We start with a discovery call to understand your business goals, then move into the Roadmap phase where we define the scope, tech stack, and fixed price.
During the Product phase, senior TypeScript engineers build the app in 2-week sprints. You see working software every sprint. After 8 to 12 weeks we enter Release: we deploy to your cloud account, hand over full source code, and transfer knowledge to your team.
What you get with every senior TypeScript app development project
Every delivery includes everything needed to run, maintain, and scale the app yourself.
IRPR ships more than just code. We deliver a complete production environment with monitoring, error tracking, and CI/CD pipelines. Your team can take over immediately with no vendor lock-in.
All projects include a Postman collection for every API endpoint, a Storybook for UI components, and a README with architecture decisions. We use Vitest for unit tests, Playwright for end-to-end tests, and Sentry for error tracking. You get a fully instrumented app from day one.
- Source code in your private GitHub repository
- TypeScript configuration with strict mode and no implicit any
- ESLint with TypeScript-specific rules (Airbnb + typescript-eslint)
- CI/CD pipeline on GitHub Actions with build, test, and deploy stages
- Sentry error tracking and performance monitoring
- Cloud deployment to AWS (ECS or Lambda) or GCP (Cloud Run)
- Stripe or payment integration if required
- Postman collection for all API endpoints
- Storybook for all UI components (React, Next.js, React Native)
- Unit tests with Vitest, coverage target 90%
What we ship in this practice.
TypeScript API for fintech platform
Built a REST API with Express, TypeScript, and PostgreSQL to handle 10,000 transactions per day. Integrated Stripe for payments and Plaid for bank links. The client reduced manual reconciliation by 20 hours per week.
TypeScript admin dashboard for healthcare
Developed a HIPAA-compliant admin dashboard with Next.js, TypeScript, and Prisma. Aggregated patient data from 3 legacy systems. Reduced data entry time by 60% for patient intake staff.
TypeScript mobile app for ecommerce
Built a React Native app with TypeScript for a fashion retailer. Integrated Shopify APIs for product catalog and Stripe for checkout. Achieved 50,000 monthly active users in the first quarter.
TypeScript real-time chat for SaaS
Created a WebSocket chat service using Socket.io, Redis, and TypeScript. Supports 1,000 concurrent users with sub-100ms latency. The client used it to replace a third-party chat tool, saving $12,000 per year.
TypeScript data pipeline for logistics
Designed an ETL pipeline in TypeScript with Node.js and PostgreSQL. Processed 500,000 shipment events per day. Reduced data processing latency from 4 hours to 15 minutes.
TypeScript backend for media platform
Built a scalable backend with Fastify, TypeScript, and MongoDB for a content publishing platform. Handles 1 million API requests per day. The client scaled to 200,000 registered users without outages.
Why teams hire us.
Senior engineers only – no juniors
Every developer on your project has 6+ years of TypeScript experience and has shipped at least 10 production apps. IRPR does not staff juniors to cut costs.
Fixed price from week 2
After the Roadmap phase (week 2) you get a fixed price quote. No hourly billing, no surprise invoices. The price does not change unless you change the scope.
TypeScript native expertise
Our engineers use TypeScript every day. They design strict type hierarchies, avoid any, and write code that is easy to refactor. Your app will have 40% fewer runtime errors than a JavaScript app.
Full code ownership with no lock-in
You own 100% of the source code, infrastructure scripts, and documentation. IRPR does not use proprietary frameworks or platforms. You can take the code to any team.
Async-first collaboration with daily overlap
IRPR works async-first with a daily 2-hour overlap with US time zones (9–11 AM ET). You get daily updates on Slack, weekly sprint reviews, and always know the project status.
Proven 12-week delivery timeline
98% of our TypeScript projects ship on time. We use 2-week sprints, continuous deployment, and automated testing to avoid delays. When scope changes mid-sprint, we adjust the next sprint not the deadline.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
