Why hire senior full stack app development consultants
We deliver production-ready apps in 12 weeks with no surprises.
IRPR's senior consultants have an average of 10+ years of experience each. We have shipped over 200 products, from simple MVPs to complex multi-tenant platforms handling millions of requests per day. Our engineers work directly with your team, writing code that is clean, tested, and documented.
Every project follows a fixed-price model after the 2-week Roadmap phase. You get a detailed scope, timeline, and cost before any development starts. No hourly billing, no scope creep. We guarantee on-time delivery with a 98% track record.
The difference between hiring senior full stack app development consultants vs a generic dev shop
Not all development teams are equal. Here is what sets IRPR apart.
Generic dev shops often assign junior developers to your project and bill by the hour. They have little incentive to finish quickly or write maintainable code. You end up paying for learning curves and rework.
IRPR assigns only senior engineers with 10+ years of experience. We work on a fixed price after the Roadmap phase. Every line of code is production-ready, tested, and documented. You own everything from day one.
- Hourly billing that encourages slow work
- Junior developers learning on your project
- No fixed scope or timeline
- You do not own the code until final payment
- No compliance expertise built in
- Hand-off after launch with minimal support
- Fixed price from week 2, no hourly billing
- Senior engineers only, average 10+ years
- Detailed scope and timeline in Roadmap phase
- Full code ownership from day one
- HIPAA, SOC 2, PCI-DSS compliance built in
- Post-launch support and maintenance included
How our senior full stack app development consultants work
A proven 4-phase process that de-risks your project from day one.
We start with a 1-week discovery call to understand your vision, users, and technical constraints. Then we move into the Roadmap phase where we define the full scope, architecture, and fixed price.
After you approve the Roadmap, our engineers build your product in 8-12 weeks using agile sprints. You see progress every week. Finally, we deploy to production and provide 30 days of post-launch support.
What ships with every senior full stack app development engagement
You get more than just code. Every project includes these deliverables.
When you hire IRPR's senior full stack app development consultants, you receive a complete package. We do not hand off a half-finished prototype. You get everything needed to run and scale your application.

- Automated test suite (unit, integration, e2e)
- Deployed infrastructure on AWS with CloudFormation
- Sentry error tracking and performance monitoring
- User authentication (Auth0 or custom JWT)
- Database schema and migration scripts
- API documentation (Swagger/OpenAPI)
- Admin dashboard for managing users and data
- 30-day post-launch support and bug fixes
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a single line of code.
Senior engineers only
Our consultants average 10+ years of experience. We do not outsource to juniors or offshore teams. Every engineer has shipped multiple production apps and can lead your project from day one.
8-12 week MVP guarantee
We have a 98% on-time delivery rate for MVPs. Our process is designed to ship a working product in 8 to 12 weeks. If we miss the deadline, you pay nothing extra.
Full ownership of code
You own all source code, infrastructure, and intellectual property from day one. There are no licensing fees or lock-in. We hand over everything at the end of the engagement.
Compliance built in
We have built applications for HIPAA, SOC 2, PCI-DSS, and FERPA. Our engineers design with compliance from the start, not as an afterthought. We include audit logs, encryption, and access controls by default.
Post-launch support included
Every project includes 30 days of post-launch support with bug fixes and monitoring. After that, we offer ongoing maintenance at a flat monthly rate. You are never left alone after launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
