Full Stack App Development ConsultantsDevelopment Consultants
We build custom web and mobile apps in 8-12 weeks. Fixed price, senior engineers, and a clear roadmap from day one.
IRPR is a full stack app development consultancy. We build web apps with React, Next.js, Node.js, Python, and Go. Mobile apps ship with React Native or Flutter. Every project uses a modern cloud stack: AWS, GCP, or Azure.
We ship MVPs in 8-12 weeks. Pricing is fixed, not hourly. A typical project costs between $80,000 and $250,000. We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance for regulated industries.
Our clients are founders validating a SaaS idea, healthcare CTOs needing HIPAA-compliant apps, fintech leaders requiring PCI-DSS security, and ecommerce directors scaling custom storefronts. They hire us because we deliver production-ready code, not prototypes.

Why hire full stack app development consultants
Building a custom app with internal teams often fails due to cost overruns and skill gaps.
IRPR has shipped 200+ products across 50+ countries. We use a fixed price model so you know the cost before a single line of code is written. Our average MVP timeline is 8-12 weeks, not 6 months.
Every engineer on our team has 10+ years of experience. We use React, Node.js, Python, Go, AWS, and PostgreSQL. We also handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA.
What makes IRPR different from other full stack app development consultants
Most agencies bill hourly and deliver late. IRPR does not.
We quote a fixed price after a 2-week Roadmap phase. That quote covers the entire build. No hourly billing, no surprise invoices, no scope creep charges.
Your team gets a dedicated project manager, a senior frontend engineer, a senior backend engineer, and a DevOps engineer. All code is yours. We deploy to your AWS account.
- Hourly billing with no cap
- Junior or mid-level engineers
- No compliance expertise
- Deliverables are loose wireframes
- Code stays in their repo
- No monitoring or support after launch
- Fixed price from week 2
- Senior engineers only (10+ years)
- HIPAA, PCI-DSS, SOC 2, FERPA built in
- Detailed technical roadmap with user stories
- Full source code in your GitHub repo
- Sentry error tracking + 99.9% uptime SLA
Our process for full stack app development
We follow a 4-phase process that de-risks your project from day one.
Every project starts with a Discovery call. We listen to your idea, ask hard questions, and decide if we are a fit. If yes, we move to the Roadmap phase.
The Roadmap phase lasts 2 weeks. We produce a detailed technical specification, user stories, wireframes, and a fixed price quote. You approve the Roadmap before any development begins.
What ships with your full stack app
You get more than code. Every project includes production infrastructure and documentation.
We do not hand over a zip file and walk away. Every project includes CI/CD pipelines, monitoring, error tracking, and a deployment guide. Your team can deploy changes 24 hours after handoff.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Staging and production environments on AWS
- Sentry error tracking and alerts
- Datadog monitoring for performance and uptime
- PostgreSQL or MongoDB database with backups
- Docker containers with docker-compose
- Swagger or GraphQL documentation
- User documentation and admin guide
- 30 days of post-launch support
What we ship in this practice.
