Why an experienced full stack app development agency matters
A generalist freelancer or junior team cannot deliver a production-ready app with security, scaling, and compliance.
IRPR has shipped 200+ products across 50+ countries. Our senior engineers average 10+ years of experience. We use React, Next.js, Node.js, Python, PostgreSQL, and AWS for every project. This stack covers 90% of modern app needs.
We handle compliance too. Healthcare apps meet HIPAA. Fintech apps meet PCI-DSS. SaaS apps meet SOC 2. We bake these standards into the architecture from day one, not as an afterthought.
How IRPR differs from other full stack agencies
Most agencies bill hourly, change scope, and assign junior devs. IRPR does the opposite.
We quote a fixed price after the Roadmap phase (week 2). You know the cost before we write production code. No hourly billing means no surprises.
Every engineer on your project is a senior with 10+ years of experience. We do not outsource to junior devs. You get direct access to the team via Slack and weekly video calls.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without change orders
- No compliance expertise
- Code ownership unclear
- No CI/CD pipeline included
- Fixed price from $80K
- Senior engineers only, 10+ years experience
- Scope locked after Roadmap phase
- HIPAA, PCI-DSS, SOC 2, FERPA built in
- You own 100% of the code
- CI/CD pipeline with GitHub Actions included
Our process for building your full stack app
We follow a 4-phase framework: Idea, Roadmap, Product, Release.
Phase 1 (Idea) is a 1-week discovery sprint. We define user stories, wireframes, and tech stack. Phase 2 (Roadmap) produces a fixed-price contract and a detailed build plan with milestones.
Phase 3 (Product) is the core build: 8-12 weeks of sprints with weekly demos. Phase 4 (Release) includes deployment to production, CI/CD setup, and a 30-day warranty.
What ships with every full stack app
Every project includes these deliverables by default. No hidden line items.
We deliver a fully functional app, not a prototype. You get the source code in your repository, a CI/CD pipeline, and a production deployment on AWS or your preferred cloud.
Documentation includes API docs, architecture diagrams, and a runbook for your team. We also provide a 30-day warranty for bug fixes after launch.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Production deployment on AWS (or your cloud)
- Sentry error tracking and monitoring
- API documentation with Swagger or Postman
- Architecture diagram and runbook
- Admin panel or dashboard (if applicable)
- Unit tests and integration tests
- 30-day post-launch warranty
- Direct Slack channel with the team
