Why Work With an Experienced Custom Application Development Vendor
IRPR has delivered 200+ applications across 50 countries, with a 98% on-time delivery rate.
Every application we build is designed for scale and compliance from day one. We have shipped telehealth apps that passed HIPAA audits on first submission, fintech platforms that handle PCI-DSS Level 1 data, and SaaS products used by thousands of users.
Our average timeline for a custom application MVP is 12 weeks. We use a fixed-price model built on detailed roadmaps completed in week 2. No hourly billing, no surprise invoices.
The Difference Between IRPR and Generic Dev Shops
Most custom development vendors bill hourly and use junior engineers to cut costs. IRPR does the opposite.
In a generic dev shop, you get a project manager who shields you from the actual engineers. The code is poorly documented, the timeline slips, and you end up paying for rework. With IRPR, you talk directly to the senior engineer building your application.
We assign a lead architect, a senior backend engineer, and a senior frontend engineer to every project. All 10+ years of experience. The same team stays with you from roadmap to release.
- Hourly billing with no cap
- Junior engineers with 1-2 years experience
- No compliance expertise (HIPAA, PCI, SOC 2)
- Vague timelines that slip 50%+
- No code ownership guarantee
- Post-launch support costs extra
- Fixed price based on a detailed roadmap (week 2)
- Senior engineers only (10+ years experience)
- Built-in compliance from day one
- 8-12 week delivery, 98% on-time
- Full code ownership – you get the repos
- 12-month post-launch support included
How IRPR Builds Your Custom Application
Our process moves from idea to production in four distinct phases, each with a clear deliverable.
In the Idea phase (week 1), we align on scope, goals, and constraints. We identify risks and decide on the core tech stack – typically Next.js, Node.js, PostgreSQL, and AWS, with Stripe or Braintree for payments when needed.
The Roadmap phase (week 2) produces a fixed-price proposal with a detailed breakdown of features, user stories, and timelines. Once approved, we move to Product – a 6-8 week build sprint with weekly demos. Release includes deployment, monitoring, and handover.
What Ships When You Hire IRPR
Every custom application project includes a standard set of deliverables – no hidden costs.
You own everything we build. Source code is in your GitHub or GitLab repo from the first commit. No proprietary frameworks, no license fees.
We set up production infrastructure on AWS or GCP with auto-scaling, SSL, and daily backups. A complete CI/CD pipeline runs tests on every push.
- Source code in your private GitHub/GitLab repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Production infrastructure on AWS (EC2, RDS, S3, CloudFront)
- SSL certificate and custom domain configuration
- Sentry error tracking and CloudWatch logging
- Admin dashboard with user management
- Payment integration (Stripe or Braintree) with test data
- API documentation (Postman collection or Swagger)
- User authentication (Auth0 or custom JWT)
- 12-month post-release support and maintenance

Our average MVP ships in 12 weeks. We use a tight 4-phase process (Idea -> Roadmap -> Product -> Release) that keeps scope under control.
Full code ownership
Every line of code is in your repository from day one. No proprietary frameworks, no reverse engineering needed. You own everything, including the IP.
