Why IRPR is the best custom application development vendor
We ship production-grade software in 8-12 weeks with a fixed price and full code ownership.
Our team of senior engineers has shipped over 200 products across 50 countries. We use a four-phase framework: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), you get a fixed quote, a detailed spec, and a delivery timeline. No scope creep, no hourly billing.
We build with modern stacks like Next.js, React Native, Node.js, and PostgreSQL. Every project includes CI/CD pipelines on GitHub Actions, error tracking with Sentry, and uptime monitoring with Datadog. You own the source code from day one.
The difference between IRPR and a generic dev shop
Most agencies bill hourly and change scope mid-project. We do the opposite.
Generic development shops often start without a clear spec. They bill by the hour, add scope, and deliver late. You never know the final cost until the project ends.
IRPR gives you a fixed price after a 2-week Roadmap phase. We define the full scope, tech stack, and timeline before coding starts. No surprises. No hourly invoices.
- Hourly billing with no cap
- Scope creep on every sprint
- No written spec before coding
- Junior developers on your project
- No compliance expertise
- Code ownership not guaranteed
- Fixed price from week 2
- Scope locked in Roadmap phase
- Detailed spec before any code
- Senior engineers only (8+ years)
- HIPAA, PCI-DSS, SOC 2 built in
- Full source code ownership
Our 4-phase process for custom application development
We follow a repeatable framework that de-risks every project.
Phase 1: Idea. We review your concept, market, and technical requirements. This takes 1-2 days and is free. Phase 2: Roadmap. We produce a detailed spec, wireframes, tech stack, and a fixed price quote. This takes 2 weeks and costs a flat fee.
Phase 3: Product. Our senior engineers build your application in 8-12 weeks. We use agile sprints with weekly demos and Slack communication. Phase 4: Release. We deploy to production, set up monitoring, and hand over all code and documentation.

You get more than just code. Every delivery includes production infrastructure and documentation.
When we finish a project, you own everything. Source code in your GitHub repo. CI/CD pipeline on GitHub Actions. Error tracking with Sentry. Uptime monitoring with Datadog. All passwords and secrets in a shared vault.
You also get a technical handover document, a user guide for your team, and a 30-day warranty period. If something breaks, we fix it for free.
