React.js consulting by the numbers
Here is what our expert React.js development consultants have delivered for clients across 50+ countries.
We have shipped over 200 React.js applications since 2016. Our average MVP delivery takes 10 weeks, from kickoff to deployed production code. 98% of projects ship on time or ahead of schedule.
Our senior React.js developers each have 8+ years of experience. We use TypeScript by default and enforce strict linting rules with ESLint and Prettier. Every project includes unit tests (Jest), integration tests (Cypress), and a CI/CD pipeline on GitHub Actions.
Generic dev shop vs IRPR React.js consultants
Not all React.js development teams deliver the same quality. Here is how we compare.
Many agencies assign junior developers to your project and bill by the hour. You never know the total cost until the end. Code quality and documentation are afterthoughts.
IRPR assigns senior engineers only with a fixed price agreed in week 2. Every project ships with full test coverage, a documented component library, and a CI/CD pipeline.
- Junior or mid-level developers
- Hourly billing with no cap
- No upfront architecture document
- No test coverage requirement
- Code delivered without CI/CD
- No post-launch support plan
- Senior React.js engineers only
- Fixed price from week 2
- Roadmap document before coding
- 100% test coverage on critical paths
- GitHub Actions CI/CD included
- 12-week post-launch support
Our 4-phase React.js consulting process
Every engagement follows the same structured process to eliminate surprises.
Phase 1 (Idea) takes 1 week. We review your concept, user needs, and technical constraints. You receive a project brief with recommended tech stack and timeline.
Phases 2 through 4 (Roadmap, Product, Release) cover architecture design, sprint-based development, and deployment. You own the repo and all code from day one.
What ships with every React.js project
Every deliverable includes these defaults. No add-on costs.
We ship production-ready code, not prototypes. Your team can take over maintenance immediately because everything is documented and tested.
All projects include GitHub Actions CI/CD, Vercel or AWS deployment, and Sentry error tracking. You own the source code and all IP from day one.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Unit tests with Jest (80%+ coverage)
- Integration tests with Cypress
- TypeScript and ESLint configuration
- Component library with Storybook
- Deployment to Vercel or AWS
- Sentry error and performance monitoring
- API documentation using Swagger or GraphQL
- 12-week post-launch support and maintenance

Every consultant on your project has 8+ years of React experience. We do not staff junior developers. Your project gets a lead engineer who has shipped at least 5 production React apps.
Fixed price, agreed in week 2
We give you a fixed price quote in the Roadmap phase. No hourly billing, no surprise invoices. The price you see is the price you pay, even if we discover more work.
10-week MVP delivery
From kickoff to production deployment, your MVP ships in 8-12 weeks. We use Next.js, Vercel, and GitHub Actions to move fast. 98% of our projects ship on time.
Compliance built in from day one
We build HIPAA, PCI-DSS, and SOC 2 compliant React apps. Our engineers know the requirements before writing a single line of code. No retroactive compliance fixes.
Full code ownership and IP transfer
You own all source code, design assets, and documentation from day one. There is no licensing fee or recurring royalty. We hand over a private GitHub repo with full history.
12-week post-launch support
After deployment, we provide 12 weeks of maintenance and support. That includes bug fixes, performance monitoring via Sentry, and one round of feature enhancements.
Idea → Roadmap → Product → Release.
