Senior TypeScript App Development CompanyApp Development
We build production-grade TypeScript apps with senior engineers only. Ship your MVP in 8-12 weeks with fixed pricing.
IRPR is a senior TypeScript app development company. We build web applications, mobile apps, APIs, and SaaS platforms using Node.js, React, Next.js, and NestJS. Every project is staffed with senior engineers who have shipped 50+ production apps in TypeScript.
We deliver a working MVP in 8-12 weeks with fixed pricing between $80,000 and $250,000. You get full code ownership, a CI/CD pipeline, and compliance support for HIPAA, PCI-DSS, and SOC 2. No hourly billing, no scope creep.
We work with startup CTOs who need a rapid MVP to raise seed rounds, enterprise engineering leads replacing legacy Java systems with TypeScript, product managers requiring a dedicated senior team for a new feature, and SaaS founders scaling their platform from 1,000 to 100,000 users.

Why a senior TypeScript development company matters
Junior-heavy teams produce bug-ridden code and delayed releases. Senior engineers ship faster with fewer defects.
A senior TypeScript app development company like IRPR assigns engineers with 10+ years of experience. Every developer has shipped at least 5 production apps in TypeScript. We use strict TypeScript settings, full test coverage, and code reviews on every pull request.
In a 2023 study, senior engineers delivered code 40% faster than mid-level developers with 60% fewer production bugs. Our projects average a 98% on-time delivery rate. We maintain 99.9% uptime on hosted apps.
How IRPR differs from generic dev shops
Most agencies hide junior staff and bill hourly. We are transparent and fixed-price.
Generic TypeScript development shops often assign junior developers to save costs. They charge by the hour, inflate estimates, and deliver incomplete solutions. You never know who is writing your code.
IRPR assigns senior engineers only. Every developer has a public portfolio of TypeScript work. We quote a fixed price after the Roadmap phase (week 2). You know the budget before any build begins.
- Hourly billing with no cap
- Junior developers with little review
- No compliance support (HIPAA, PCI)
- Code ownership often disputed
- No dedicated project manager
- Scope creep without change orders
- Fixed price from day one
- Senior engineers only (10+ years)
- Built-in HIPAA, PCI-DSS, SOC 2
- Full code ownership signed over
- Dedicated lead engineer and PM
- Strict change control in Roadmap
Our 4-phase process for senior TypeScript development
We start with a 2-day Discovery then deliver a fixed-price Roadmap in week 2.
Phase 1: Discovery (days 1-2). We interview your team, review existing code, and define the app's core scope. You get a document outlining every feature.
Phase 2: Roadmap (week 2). We produce a detailed plan with wireframes, database schema, API design, and a fixed price. You approve or walk away with zero cost.
What ships with every senior TypeScript app
You own everything. No black boxes, no locked-down code.
From day one, all code is developed in your private GitHub repository. You have full access and creative control. At launch, we deliver a complete production-ready system.
- Source code in your GitHub repo with full access
- CI/CD pipeline using GitHub Actions or CircleCI
- Sentry error tracking with 30-day retention
- Automated test suite (unit, integration, e2e)
- Deployment to AWS (ECS, Lambda) or GCP (Cloud Run)
- PostgreSQL database with migrations and backups
- API documentation (Swagger/OpenAPI)
- Admin panel for data management
- Stripe / payment integration test mode
- One-year dependency update guarantee
