Senior Frontend App Development PartnerDevelopment Partner
We build frontends that load fast, scale to millions, and ship in 12 weeks. Experienced teams. Fixed price.
IRPR is a senior frontend app development partner that builds production-ready web applications with React, Next.js, TypeScript, and Tailwind CSS. We design and implement component libraries, state management, API integration layers, and responsive layouts that work on every screen.
Most projects ship in 8 to 12 weeks. Fixed pricing starts at $80,000 and goes to $250,000 depending on scope. We support HIPAA, PCI-DSS, SOC 2, and other compliance standards out of the box.
Enterprise engineering managers hire us to replace slow legacy frontends. Startup CTOs hire us to launch their first customer-facing MVP. Product directors hire us to build internal dashboards and customer portals without hiring 10 new people.

Why work with a senior frontend app development partner
Building a frontend that performs, scales, and ships fast requires more than React knowledge. It requires architectural decisions that prevent rewrites.
IRPR has shipped over 200 frontends across 50 countries. Every project goes through our 4-phase framework: Idea (1 week), Roadmap (1 week), Product (8-12 weeks), Release (1 week). That structure guarantees on-time delivery and predictable costs.
Our senior frontend engineers average 10+ years of experience. They have built payment flows for PCI-compliant platforms, real-time dashboards for logistics companies, and patient-facing portals with HIPAA audit trails.
Senior frontend app development vs. hiring a generic dev shop
Many teams waste time fixing frontend code written by junior developers or agencies that treat UI as an afterthought.
A generic dev shop gives you a vague estimate, uses hourly billing, and hands over a zip file with no CI/CD pipeline. You end up owning a frontend that breaks on every minor dependency bump.
IRPR treats frontend as a product. We write tests, set up automated deployment through GitHub Actions, and deliver your source code on your own repository. You get a running application, not a prototype.
- Hourly billing with no cap
- Vague specs and unclear deliverables
- No automated testing
- No CI/CD setup at handoff
- Code delivered on a USB drive or zip
- You own nothing after payment
- Fixed price quoted in Roadmap phase (week 2)
- Detailed user stories and wireframes before development
- Unit tests, integration tests, and accessibility audits built in
- CI/CD on GitHub Actions or GitLab CI from day one
- Source code in your own Git repository with full history
- You own the code, the design system, and the infrastructure
Our process for building your senior frontend app
We follow a repeatable 4-step framework that eliminates guesswork and keeps every project on budget.
Each phase has clear deliverables. You know exactly what you get and when you get it. Changes are priced upfront, not discovered mid-sprint.
The Product phase is the longest. We build in 2-week sprints with daily standups and weekly demos. By week 6 you have a working frontend deployed on a staging URL.
What ships with every senior frontend engagement
Every project comes with a standard set of deliverables that guarantee quality and maintainability.
We don't hand off a messy project folder. Every repository follows a consistent structure with environment variables, linting rules, and automated checks.
You also get documentation explaining component hierarchy, data flow, and deployment steps. Your internal team can maintain the codebase without IRPR's help.
- Source code in your own Git repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Automated unit tests and integration tests (Jest, Cypress)
- Accessibility audit report (WCAG 2.1 AA)
- Lighthouse performance report (score > 85 target)
- Design system documentation in Storybook
- Deployment guide and runbook (Markdown)
What we ship in this practice.
SaaS analytics dashboard
Built a real-time analytics dashboard for a startup that tracked user events across 1M+ daily records. Used React, D3.js, and WebSocket updates. Reduced page load time from 6 seconds to 1.2 seconds.
Telemedicine patient portal
Developed a HIPAA-compliant patient portal with secure video calling, appointment scheduling, and lab result display. Tech stack: Next.js, Twilio, Auth0. Cut patient onboarding time by 40%.
E-commerce storefront with headless CMS
Replaced a legacy Magento frontend with a headless React storefront connected to Contentful and Shopify Storefront API. Increased conversion rate by 22% and improved mobile speed score from 45 to 92.
Internal tool for logistics routing
Built a drag-and-drop route optimization tool for a logistics company. Used React, Mapbox, and WebSockets to update 500+ drivers in real time. Saved dispatchers 10 hours per week.
Real-time collaboration whiteboard
Created a multiplayer whiteboard with infinite canvas for a EdTech startup. Used React, Canvas API, and Liveblocks. Supported 50 concurrent users with zero perceptible lag.
Fintech investment dashboard
Designed a portfolio management dashboard with interactive charts and transaction history. Used React, highcharts, and Stripe Connect for payment flows. Passed PCI-DSS audit on first attempt.
Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly rates, no surprise invoices, no scope creep charges. That price is what you pay.
Senior engineers only
We don't hire juniors or outsource. Every engineer has 8+ years of frontend experience. They have built production systems for fintech, healthcare, and SaaS platforms.
Full code ownership
You own the source code, the design system, and all infrastructure from day one. There is no hidden intellectual property. You can take the code anywhere.
Compliance built in, not bolted on
We design for HIPAA, PCI-DSS, and SOC 2 from the start. Authentication, logging, and encryption are part of the architecture, not a post-launch checklist.
98% on-time delivery
We track every sprint against the Roadmap. If something slips, you know within 24 hours. Most projects launch within the 8-12 week window.
Post-release support and monitoring
After launch we stay for 30 days to handle issues. We set up Sentry, uptime monitoring, and a runbook so your team can operate independently.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
