Why hire senior React.js development developers from IRPR
IRPR has shipped over 200 React.js projects for clients in 50+ countries.
Our senior React.js development developers average 10+ years of experience with React, Redux, Next.js, and TypeScript. We do not use junior or mid-level engineers. Every developer on your project has shipped at least 5 production React apps.
We work in your time zone with at least 4 hours of overlap. Communication happens in Slack, Jira, and weekly video calls. You get a project manager and a QA engineer as part of the team, no extra charge.
How IRPR differs from generic dev shops
Most agencies sell you a team then swap in junior developers. IRPR does not.
Generic dev shops promise senior React developers but deliver junior engineers who learn on your project. They bill by the hour and extend timelines. You never know the final cost until the project ends.
IRPR gives you a fixed quote after the Roadmap phase (week 2). The team is the same from day one. If a developer leaves, we replace them with someone of equal or higher skill within 48 hours.
- Bills by the hour, no fixed price
- Assigns junior developers
- No compliance expertise
- Delays scope without notice
- No QA engineer on team
- Code ownership unclear
- Fixed price after Roadmap phase
- Senior React.js developers only
- HIPAA, PCI-DSS, SOC 2 built in
- Scope changes communicated with cost impact
- QA engineer included in every team
- Full code ownership from day one
Our process for senior React.js development
We follow a four-phase process that guarantees a working product in 8-12 weeks.
Phase 1 (Idea) takes 1 week. We map your requirements, user stories, and technical constraints. You get a product brief with wireframes and a tech stack proposal.
Phase 2 (Roadmap) takes 1 week. We create a detailed plan with milestones, a fixed price, and a delivery date. You approve before any code is written.
What ships with your React.js project
Every project includes these deliverables by default, no add-ons or hidden fees.
You own everything. Source code, design assets, documentation, and deployment scripts are transferred to your GitHub or GitLab account. No licensing fees, no ongoing royalties.
We set up CI/CD with GitHub Actions, error tracking with Sentry, and performance monitoring with Datadog. Your app is ready for production from day one.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking configured
- Datadog performance monitoring
- Unit tests with Jest and React Testing Library
- End-to-end tests with Cypress
- Deployment to AWS, GCP, or Azure
- Post-launch 30-day warranty
- Technical documentation (README, API docs)
- Design assets (Figma files, SVGs)
