Why choose a senior full stack development agency?
You get a team that ships production code fast, without junior-level mistakes.
A senior full stack development agency like IRPR assigns engineers with 8+ years of experience. No juniors, no interns. Every line of code is reviewed by a peer. We use React, Node.js, PostgreSQL, and AWS to build scalable, maintainable applications.
Our fixed-price model means you know the cost upfront. In the Roadmap phase we define every feature, then lock the price. Average project is $80K to $250K and ships in 8-12 weeks. Over 200 products have shipped this way.
The difference between IRPR and a generic dev shop
Most agencies hire junior developers and bill by the hour. We do the opposite.
Generic dev shops often assign fresh graduates to your project. They use hourly billing, which rewards slowness. Scope creep is common because there is no fixed price. Code quality suffers because no one reviews it.
IRPR assigns senior engineers only. We give you a fixed price after a two-week Roadmap. Every project includes automated testing, CI/CD, and code review. You own the source code from day one.
- Junior developers with 1-2 years experience
- Hourly billing – you pay for learning
- No fixed scope – scope creep is standard
- No code review process
- No CI/CD pipeline by default
- You do not own the code until final payment
- Senior engineers with 8+ years experience
- Fixed price after Roadmap phase
- Scope defined and locked in week 2
- Peer-reviewed code on every pull request
- CI/CD pipeline on GitHub Actions from day one
- Full source code ownership from kickoff
How we build your full stack product
Four phases, no surprises, from idea to release.
Every project follows the same process: Idea, Roadmap, Product, Release. This structure eliminates ambiguity. You know exactly what you get and when.
In the Roadmap phase we create a detailed spec with wireframes, user stories, and a fixed price. The Product phase is a series of two-week sprints with demos every Friday. Release includes deployment, monitoring, and documentation.
What ships with every project
You get more than code. Every deliverable is production-ready.
When we finish a project, you receive a complete package. No missing pieces, no hidden dependencies. Everything you need to run, maintain, and scale your application.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated test suite (unit, integration, e2e)
- Deployment scripts for AWS or your cloud
- Sentry error tracking configured
- Datadog monitoring dashboard
- API documentation (OpenAPI/Swagger)
- Admin panel for data management
- User authentication (JWT or OAuth)
- Compliance documentation (HIPAA, PCI, SOC 2 if applicable)
