Why hire the best full stack development consultants
IRPR has shipped 200+ products across 50+ countries with a 98% on-time delivery rate.
When you hire IRPR as your full stack development consultant, you get a dedicated senior engineer who owns the project from start to finish. We do not outsource to junior devs. Every line of code is written by a developer with 10+ years of experience.
We use a fixed-price model. After a 2-week Roadmap phase, you get a fixed quote for the entire build. No hourly billing, no scope creep. The average MVP ships in 10-12 weeks and costs $80K-$150K.
What sets IRPR apart from other full stack consultants
Most development shops promise speed but deliver delays. IRPR ships on time with fixed pricing.
Generic dev shops often assign junior developers, change scope mid-project, and bill by the hour. You never know the final cost until the project is done. Many projects run 6-12 months over schedule.
IRPR assigns a senior engineer from day one. We scope the project in a 2-week Roadmap phase, give you a fixed price, and ship in 8-12 weeks. You own the code, the CI/CD pipeline, and all credentials.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- Scope creep without change orders
- No compliance expertise (HIPAA, PCI, SOC 2)
- Deliverables often 3-6 months late
- You do not own the source code
- Senior engineers with 10+ years experience
- Fixed price after 2-week Roadmap
- Scope defined upfront, changes managed
- Built-in compliance for HIPAA, PCI-DSS, SOC 2, FERPA
- 98% on-time delivery rate
- Full source code and infrastructure ownership
How IRPR builds your full stack application
Our process has four phases: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1: Idea. We align on your vision, target users, and core features. This takes 1 week and costs nothing if you book a discovery call.
Phase 2: Roadmap. We produce a detailed spec, architecture diagram, data model, and fixed price quote. This takes 2 weeks and costs $5,000-$10,000, credited toward the build.
What ships with every full stack project
Every project includes production-grade infrastructure, monitoring, and full code ownership.
We do not just hand over a code repository. You get a fully deployed application with CI/CD, error tracking, uptime monitoring, and documentation. Everything is set up so your team can take over immediately.
All projects include a private Slack channel with the engineering team, weekly demo calls, and a shared project board. You see progress in real time.
- Source code in your private GitHub or GitLab repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Production deployment on AWS, GCP, or Azure
- PostgreSQL or MongoDB database with automated backups
- Sentry error tracking and Datadog performance monitoring
- REST or GraphQL API documentation with Swagger or GraphQL Playground
- User authentication with Auth0 or Firebase Auth
- Admin panel for content and user management
- Unit tests and integration tests with Jest or Cypress
- 30-day post-launch warranty for bug fixes
