Senior React Web Development ConsultantsReact Web
We build production-grade React apps in 8-12 weeks. Fixed price, no surprises, senior engineers only.
IRPR is a team of senior React engineers who build web applications for demanding use cases. We use React 18, TypeScript, Next.js, and Node.js to deliver production-ready code. Our consultants have shipped 200+ products across fintech, healthcare, and SaaS.
Every project ships in 8 to 12 weeks for a fixed price between $80,000 and $250,000. We handle compliance like HIPAA, PCI-DSS, and SOC 2. The code is yours - source, tests, CI/CD, everything.
We work with founders who need a working MVP in under 3 months, CTOs who need senior React developers without a long hiring process, and product managers who must modernize a legacy frontend. No junior overhead, no hourly billing.

Why companies hire senior React web development consultants
Your React app needs more than a junior coder. It needs senior engineers who have shipped at scale.
IRPR's senior React consultants have built for 200+ products across 50 countries. We know how to structure state in apps with 10,000+ components, how to optimize bundle sizes for sub-second load times, and how to set up CI/CD pipelines that deploy to production 12 times a day without breaking.
We start every engagement with a two-week Roadmap phase. We review your spec, estimate the work, and fix a price. No hourly billing, no scope creep. Once you approve the Roadmap, we build your React app in 8 to 12 weeks and hand over the complete source code, tests, and deployment scripts.
Generic dev shop vs senior React consultants at IRPR
Most dev shops bill hourly and pass juniors as seniors. IRPR only does fixed-price projects with proven engineers.
When you hire generic development shops, you get unknown developers who learn React on your dime. Sprints slip, code quality drops, and you end up paying for rewrites. IRPR takes a different approach.
We assign senior engineers (7+ years of React experience) who have shipped at least 10 production apps each. You get a single point of contact, daily standups, and a fixed price from week two.
- Uses hourly billing that rewards slow work
- Assigns mid-level or junior developers
- No fixed scope - scope creep is your problem
- Delivers in 16-24 weeks for the same feature set
- Code quality varies - no automated tests
- You own nothing until final payment
- Fixed price locked in week 2
- Senior React engineers with 7+ years experience
- Pre-defined scope with a Roadmap contract
- Delivers in 8-12 weeks, guaranteed timeline
- Full test coverage (Jest, React Testing Library)
- Complete source code ownership from day one
How our senior React consultants work
A proven 4-step process that reduces risk and speeds delivery.
We don't start coding blindly. Every engagement follows our Idea - Roadmap - Product - Release framework. The Roadmap phase (week 2) produces a detailed spec, UI mockups, and a fixed price contract. After that, development runs in 2-week sprints with demos every sprint.
You get a Slack channel with the entire team, Jira for task tracking, and a staging environment where you can test every build. Our engineers write unit tests, integration tests, and end-to-end tests (Cypress) for every feature.
What ships with every senior React engagement
You get a production-ready application with full ownership and no technical debt.
Every React project from IRPR includes a complete delivery package. We don't just hand over code - we hand over a working system that your team can maintain and extend from day one.
All code is written to production standards: TypeScript strict mode, reusable component patterns, and automated testing. You get a CI/CD pipeline that builds, tests, and deploys to your cloud infrastructure.
- Complete React source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Unit and integration tests (Jest + React Testing Library)
- E2E tests with Cypress (critical user flows)
- Storybook component documentation
- Deployment scripts for AWS / GCP / Vercel
- Sentry error tracking and monitoring
- Design system documentation (Figma + Storybook)
- Post-launch support window (2 weeks)
- 1-hour handoff session with your internal team
