Why IRPR is the best custom web app development company
We ship faster with better quality because our process is built for results.
With over 200 products shipped and across 50 countries, IRPR has a proven track record. 98% of our projects finish on time or early. We use a fixed-price model so you never pay more than the quote you get in week 2.
Our engineers average 7+ years of experience. We don't offshore or hire juniors. Every project gets a dedicated product manager and a senior tech lead who codes alongside the team.
IRPR vs generic development shops
Here's what you get when you hire the best custom web app development company instead of a generic shop.
Generic shops often operate on hourly billing with unclear scope. They assign junior developers and have no compliance knowledge. Code ownership is often disputed, and timelines slip.
IRPR works differently. We give you a fixed price after a two-week Roadmap phase. All engineers are senior - average 7+ years. We handle HIPAA, PCI-DSS, and SOC 2. You own all code from day one.
- Unclear scope that grows
- Hourly billing with no cap
- No compliance knowledge
- Junior developers or offshore teams
- Disputed code ownership
- Timeline often doubles
- Fixed price after Roadmap phase
- 12-week delivery guarantee
- HIPAA / PCI-DSS / SOC 2 expertise
- Senior-only engineers (7+ years exp.)
- Full code ownership - you own everything
- Dedicated product manager and tech lead
Our process for building custom web apps
Four phases that deliver a production-ready product in under 12 weeks.
We start with a one-week Idea Workshop where we define core features, choose the tech stack, and align on goals. By the end of week 2 you get a detailed Roadmap with a fixed price.
Then we build in two-week sprints with weekly demos. You see working software every Friday. In the final phase we deploy to production, set up monitoring with Sentry, and hand over all code and documentation.
What ships with every custom web app
Everything you need to launch and maintain your application.
Every project includes a complete set of deliverables so you can run the app from day one. No hidden extras or surprise requirements.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error tracking configured
- Cloud hosting setup on AWS (EC2, RDS, S3)
- Automated unit and integration tests
- API documentation via Swagger / OpenAPI
- Admin dashboard with user management
- Role-based access control (RBAC)
- Responsive design for mobile and desktop
- Performance monitoring with New Relic
What we ship in this practice.
Medication adherence platform
We built a HIPAA-compliant patient portal using React, Node.js, and Twilio for video visits. The client reduced missed appointments by 35% and onboarded 2,000 patients in the first month. Built with Next.js, PostgreSQL, and AWS.
Investment portfolio dashboard
A fintech startup needed a real-time dashboard for portfolio tracking. We used React, Node.js, and Plaid for banking connections. The app handles 10,000+ transactions per day with 99.9% uptime and reduced manual data entry by 8 hours per week.
Custom ecommerce checkout engine
An established retailer wanted to move from Shopify to a custom checkout that integrates with their warehouse API. We built the frontend with Next.js and the backend with Node.js + Stripe. Cart abandonment dropped by 22% and checkout speed improved 3x.
SaaS subscription management tool
A B2B SaaS company needed a multi-tenant platform that handles usage-based billing. We used React, Node.js, and Stripe. The client went from zero to 500 paying subscribers in 12 weeks and cut churn by 18% thanks to automated dunning emails.
Real estate listing portal with MLS
A real estate aggregator wanted a portal that syncs MLS data in real time. We built the app with React, Node.js, and Mapbox. The site now indexes 3 million listings and serves 100,000 monthly active users.
Online learning platform with gamification
An edtech company needed a platform that tracks student progress and awards badges. We used Next.js, Node.js, and PostgreSQL. The client onboarded 15 schools in the first quarter and reported a 40% increase in student engagement.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing means no surprise invoices and no scope creep charges. You know the exact cost before we write a line of code.
Senior-only engineers
All our engineers have 7+ years of experience. We never hire juniors or outsource to offshore teams. Your project is led by a tech lead who codes alongside the team and reviews every pull request.
Compliance built in
We have deep experience with HIPAA, PCI-DSS, and SOC 2. We bake compliance into the architecture from day one - not as an afterthought. This saves you months of rework and audit stress.
Full code ownership
You own 100% of the code, designs, and IP. We put everything in your GitHub repository from the first commit. No lock-in, no licensing fees, no vendor hostage.
8-12 week delivery guarantee
We have shipped 200+ products on time with a 98% on-time delivery rate. Our sprint process and fixed scope mean predictable timelines. If we slip, we tell you by week 4, not week 12.
Post-launch support included
We provide 30 days of free support after launch. This covers bug fixes, monitoring adjustments, and knowledge transfer. We also offer retainer options for ongoing maintenance.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
