Why Companies Choose IRPR as Their Full Stack Partner
We ship working software in weeks, not quarters. Every project follows a repeatable 4-step framework.
From a single-page web app to a multi-tenant SaaS platform, IRPR has delivered 200+ products for clients in 50 countries. Our senior engineers average 10+ years of experience and have built systems that handle 50,000 concurrent users. We do not hire juniors or offshore agencies that resell your work.
The difference is our fixed pricing model. After the Roadmap phase (week 2), you get a firm price for the entire scope. No hourly billing, no time tracking, no surprises. The average MVP costs $80K-$250K and ships in 8-12 weeks. You own the source code, the infrastructure, and the IP.
Fixed Price vs. Hourly Billing
Most development agencies bill by the hour and profit from scope creep. IRPR quotes a fixed project price.
When you hire a generic dev shop, you pay for their inefficiency. They bill for meetings, research, and rework. The average hourly shop costs 30% more than the original estimate. You never know the final price until the project is over.
IRPR spends week 2 building a detailed Roadmap with wireframes, user stories, and a timeline. The price is locked from that point. If we find a faster way to build, you pay less. If the scope changes, we adjust the price before work begins. No invoices change after a sprint starts.
- Hourly billing with no cap
- Scope creep on every feature
- Junior developers with oversight
- Code you do not own without paying
- No compliance expertise
- Delays from miscommunication across time zones
- Fixed price per phase (Roadmap -> Product -> Release)
- Scope changes only after agreement
- Senior engineers only (10+ years avg.)
- Full source code ownership from day one
- HIPAA, PCI, SOC 2 built in (not bolt-on)
- Async-first communication with daily standups in your timezone
Our 4-Phase Full Stack Development Process
We use the same framework for every project. It removes guesswork and delivers software that works.
Phase 1 is the Idea workshop. We interview stakeholders, map user flows, and validate assumptions. Phase 2 is the Roadmap: wireframes, tech stack decision (Next.js vs. Remix, PostgreSQL vs. MongoDB), fixed price, and a 2-week sprint plan.
Phase 3 is Product: we build in 2-week sprints, deploy to staging, and demo every sprint. Phase 4 is Release: infrastructure hardening, load testing, monitoring, and handover. You get AWS or Azure production environment, CI/CD pipeline, and a 30-day warranty.
What Ships With Every Full Stack Project
Every deliverable is production-ready and documented. You are never left with half-built code.
All projects include a fully configured DevOps pipeline. We use GitHub Actions, Docker, AWS EC2 or ECS, and a monitoring stack with Sentry and Datadog. The infrastructure is coded in Terraform, so you can spin up staging environments in minutes.
You also receive a technical readme, API documentation (Swagger), and a handoff video. We train your team on the codebase and support you for 30 days after launch. There is no black box.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Production infrastructure on AWS or Azure
- Sentry error tracking and performance monitoring
- Dockerized application with docker-compose
- API documentation (Swagger / OpenAPI)
- Load test results (k6 scripts)
- Security scan report (OWASP top 10)
- Admin panel or dashboard for non-technical users
- 30-day post-launch warranty and support

HIPAA, PCI-DSS, SOC 2, FERPA, and ISO 9001 projects are our specialty. We audit the infrastructure before launch and provide compliance documentation.
8-12 week MVPs
Most projects ship in 8 to 12 weeks. We use a repeatable framework and pre-built components (e.g., auth, billing, notifications) to accelerate development.
Full ownership, no lock-in
You own the code, the AWS account, the domain, and the IP from day one. We transfer everything to your GitHub org and cloud account.
