Why senior custom application development matters
A senior team means fewer rewrites, faster delivery, and production-ready code from day one.
Junior developers often create technical debt that slows down future features. With IRPR, every line of code is written by engineers who have shipped 50+ products. We use proven patterns and automated testing to avoid bugs.
Our fixed price model means you know the cost before we write a single line. We define the scope in a 2-week Roadmap phase. After that, the price never changes.
Generic dev shops vs. a senior agency
Not all development teams deliver the same quality. Here is how IRPR compares.
Many agencies staff projects with junior developers and charge hourly. They have no incentive to finish fast. IRPR uses senior engineers only and charges a fixed price. We finish faster because we want to start your next project.
We also handle compliance from the start. HIPAA, PCI-DSS, and SOC 2 are built into our development process, not added as an afterthought.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance expertise
- Code ownership unclear
- Long timelines due to rework
- No post-launch support
- Senior engineers with 10+ years each
- Fixed price from the Roadmap phase
- HIPAA, PCI, SOC 2 compliance built in
- Full code ownership in your repo
- 8-12 week delivery on MVPs
- Post-launch monitoring and maintenance
How we build your custom application
Our 4-phase process removes guesswork. You see progress every week.
We start with a 2-week Roadmap phase where we define the scope, tech stack, and fixed price. No code is written until you approve the plan. This phase costs a flat fee that goes toward the total project cost.
After that, we build your MVP in 8-12 weeks with weekly demos. You see working software every Friday. We deploy to staging and then production with your approval.
What ships with every custom application
You get more than just code. Every project includes these deliverables by default.
We believe in full transparency. You get access to the same tools we use internally: GitHub, Sentry, and AWS. No black boxes.
Our documentation covers architecture, API endpoints, and deployment steps. Your team can take over maintenance without a learning curve.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- AWS or GCP infrastructure as code (Terraform)
- Postman collection for all API endpoints
- Architecture diagram and README documentation
- Staging and production environments
- 99.9% uptime SLA with monitoring alerts
- 1 month of post-launch support and bug fixes

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 cost before we write code.
Senior engineers only
Every developer on your project has 10+ years of experience. We do not staff juniors. Our team has shipped 200+ products across 50 countries.
8-12 week delivery
We ship MVPs in 8-12 weeks because we use proven architectures and reusable components. Faster delivery means you get to market sooner and start learning from real users.
Full code ownership
You own the source code, the infrastructure, and all intellectual property. We put everything in your GitHub repo and AWS account. No lock-in.
Compliance built in
HIPAA, PCI-DSS, and SOC 2 are part of our development process, not afterthoughts. We use encryption, access controls, and audit logs from day one.
Post-launch support included
Every project includes 1 month of post-launch support with monitoring, bug fixes, and documentation. We hand over a running system, not just code.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
