Senior Custom Web App Development StudioSenior Custom
We build production-grade web apps with senior engineers only. 200+ products shipped in 12 weeks or less.
IRPR is a senior custom web app development studio. We build web applications using Next.js, Node.js, Python, and React with PostgreSQL or MongoDB on AWS or GCP. Every engineer on your project has 8+ years of experience and has shipped production software before.
We deliver a working MVP in 8-12 weeks. Pricing is fixed and starts at $80K for a standard web app, ranging to $250K for complex multi-service applications. All projects include CI/CD pipelines, automated tests, and HIPAA or SOC 2 compliance when required.
Founders who need a technical co-founder hire us to build their first product. CTOs at mid-market companies hire us to build internal tools or customer-facing portals. Agencies hire us to white-label development when their own team is at capacity.

Why choose a senior custom web app development studio
Senior engineers ship faster and with fewer bugs than junior teams. Here is the data.
IRPR hires only senior engineers with 8+ years of experience. Our average engineer has shipped 5+ production web apps before joining. This means your project starts with architects who have seen common failure patterns and know how to avoid them.
We use a fixed-price model based on a detailed roadmap. In week 2 of the project, we deliver a technical specification with wireframes and a fixed quote. You approve the scope and price before any code is written. No hourly billing, no scope creep.
What sets IRPR apart from other development agencies
Most agencies staff juniors and bill hourly. We do the opposite.
We interviewed 500+ engineers to build our team of 30 senior developers. Every engineer passes a technical screen, a system design interview, and a paid trial project. You never get a junior who needs hand-holding.
All communication happens in a shared Slack channel with your team. We use Linear for task tracking and Notion for documentation. You see progress every day, not just at sprint reviews.

How we build your custom web app in 12 weeks
Our process is designed for speed without sacrificing quality.
We follow a four-phase approach: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline. You know exactly what you get and when.
The Roadmap phase is the most critical. In week 2, we deliver a technical specification with wireframes, database schema, API design, and a fixed price. You approve this before we write any production code.
What you get when you hire IRPR
Every project ships with these deliverables by default. No hidden fees.
We believe in full transparency. You own everything we build, from the first line of code to the final deployment script. There are no licensing fees, no ongoing royalties, no hidden costs.
Our standard delivery includes a production-ready web app, a CI/CD pipeline, automated tests, monitoring, and documentation. You can take the code and run it yourself or continue working with us for ongoing support.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated unit and integration tests (Jest, Cypress)
- Sentry error tracking and monitoring
- Production deployment on AWS or GCP
- Database schema and migration scripts
- API documentation (Swagger or Postman collection)
- Admin dashboard for managing users and data
- User authentication with Auth0 or NextAuth.js
- 1 month of post-launch support and bug fixes
