Why IRPR Delivers the Best Custom Web App Development
We focus on shipping working software that solves real problems, not on buzzwords.
IRPR has shipped 200+ custom web applications across 50 countries. Our senior engineers average 10+ years of experience. We use React, Next.js, Node.js, Python, and PostgreSQL for every project. Each app is built with CI/CD, automated testing, and monitoring from day one.
Our process is simple. You share your idea. We build a Roadmap in week 2 with fixed scope and price. Then we ship your MVP in 8 to 12 weeks. No hourly billing, no scope creep, no surprises. You own the full source code and all IP.
How IRPR Differs from Other Web App Development Companies
Most agencies sell you hours. We sell you a finished product.
Generic development shops bid on hourly rates and change orders. They often understaff projects with junior developers. You end up paying for meetings, revisions, and learning time. The final product may not match your vision or meet compliance standards.
IRPR works differently. We assign a team of senior engineers who have built similar apps before. We give you a fixed price after the Roadmap phase. Every app includes automated tests, CI/CD pipelines, and monitoring. We ship on time or we tell you before the deadline.
- Hourly billing with no cap
- Junior developers learning on your project
- No fixed timeline or scope
- You own nothing until final payment
- No compliance expertise
- Handoff with no documentation
- Fixed price after Roadmap phase
- Senior engineers only (10+ years avg)
- 8-12 week MVP delivery
- Full source code and IP ownership from day one
- HIPAA, PCI-DSS, SOC 2, FERPA ready
- CI/CD, tests, monitoring included
Our Process for Building Your Custom Web App
We follow a four-phase process that guarantees clarity and speed.
Phase 1 is the Idea call where we understand your problem, users, and goals. Phase 2 is the Roadmap where we define architecture, tech stack, timeline, and fixed price. Phase 3 is Product where we build the app in 8 to 12 weeks. Phase 4 is Release where we deploy to production and hand over everything.
Each phase has clear deliverables. You see working software every two weeks. No long waits for a demo. You can change priorities between sprints without breaking the budget because we already scoped the entire project.
What Ships with Every Custom Web App
Every project includes production-grade infrastructure, not just code.
When IRPR builds your web app, you get more than a working application. You get a complete production environment. We set up cloud infrastructure on AWS or GCP, configure CI/CD pipelines, and add error monitoring with Sentry. Your team can deploy changes immediately after handoff.
We also include documentation for all APIs, database schemas, and deployment steps. You own everything. There is no vendor lock-in. If you want to switch teams later, they can pick up the codebase without a learning curve.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Cloud infrastructure on AWS or GCP (Infrastructure as Code)
- Sentry error tracking and performance monitoring
- Automated test suite (unit, integration, e2e)
- API documentation (OpenAPI/Swagger)
- Database schema and migration scripts
- Deployment runbook and admin guides
- 30-day post-release support and bug fixes
- Full intellectual property ownership

Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a single line of code.
Senior engineers only, no juniors
Our developers average 10+ years of experience. We do not staff junior engineers on client projects. Every team member has shipped at least 5 production web apps before joining IRPR.
8 to 12 week MVPs, not 6 months
We ship your first working version in 8 to 12 weeks. Our process eliminates long discovery phases and endless meetings. You see working software every two weeks.
Full ownership from day one
You own the source code, IP, and all deliverables from the first sprint. There is no license fee, no ongoing royalty, no vendor lock-in. Your code lives in your own GitHub repo.
Compliance-ready for regulated industries
We have built apps for HIPAA, PCI-DSS, SOC 2, and FERPA. Our engineers know how to handle PHI, PII, and card data. We include compliance controls in the Roadmap phase.
