Senior Custom Web App Development AgencySenior Custom
We build production-grade web applications with senior engineers. 200+ products shipped in 50+ countries.
IRPR is a senior custom web app development agency that builds web apps using Next.js, React, Node.js, Python, and PostgreSQL. We skip junior developers and staff augmentation models entirely.
Every project ships in 12-14 weeks for a fixed price between $80K and $250K. We handle compliance requirements like HIPAA, PCI-DSS, and SOC 2 as part of the build, not as an add-on.
We work with CTOs who need to launch a SaaS MVP without technical debt. Founders who want a production-ready web app in 12 weeks. Enterprise teams that need a PCI-DSS compliant application for their fintech product. And healthcare companies requiring HIPAA-compliant patient portals.

Why Hire a Senior Custom Web App Development Agency
Most agencies assign junior developers to your project. IRPR assigns senior engineers only.
We have shipped over 200 custom web apps for clients in 50 countries. Every engineer on our team has 7+ years of experience building production-grade applications. No junior developers. No offshore teams with timezone gaps.
Our senior engineers work directly with your CTO or product manager. They write code, review pull requests, and deploy to production. You get a senior engineer who understands your business, not a rotating cast of contractors.
How IRPR Differs from Other Custom Web App Agencies
We fix the problems that plague most custom web app projects.
Generic dev shops promise everything and deliver half. They use hourly billing, change requirements mid-project, and hand you code with no tests or documentation. IRPR does the opposite.
We start with a fixed-price Roadmap phase that defines every feature, integration, and compliance requirement. You approve the scope before we write a single line of code. Then we build in 2-week sprints with daily standups and weekly demos.
- Assigns junior developers to your project
- Uses hourly billing with no cap
- Changes scope without written approval
- Delivers code with no tests or CI/CD
- No compliance expertise (HIPAA, PCI, SOC 2)
- Hands over code and disappears
- Assigns senior engineers with 7+ years experience
- Fixed price from Roadmap phase (week 2)
- Scope defined upfront, changes approved in writing
- Full CI/CD pipeline, automated tests, Sentry monitoring
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Hands over source code, deploys to your AWS account
Our Process for Building Custom Web Apps
We follow a four-phase process that takes your idea to production in 12-14 weeks.
Every project starts with the Idea phase where we review your requirements, user personas, and technical constraints. This takes 1 week and costs nothing if we move to Roadmap.
The Roadmap phase produces a detailed technical specification, wireframes, and a fixed price quote. You approve the scope and we start building in 2-week sprints. Production deployment happens in the Release phase with full monitoring and documentation.
What Ships With Every Custom Web App
You own everything. Source code, infrastructure, and documentation.
When IRPR builds your custom web app, you get more than just working software. You get a production-ready system with monitoring, testing, and deployment automation. Every project includes the following deliverables by default.
No hidden fees. No licensing costs. No ongoing royalties. The code is yours to deploy, modify, and sell. We set up everything in your AWS, GCP, or Azure account so you have full control from day one.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated test suite with Jest and Cypress
- Sentry error tracking with alerts
- Deployment to your AWS, GCP, or Azure account
- User authentication via Auth0 or Clerk
- Database schema and migration scripts (PostgreSQL or MongoDB)
- API documentation with Swagger or Postman
- Admin panel for managing users and data
- 30 days of post-launch support and bug fixes
