What Senior Custom Software Development Developers Deliver
A senior team brings experience that junior teams cannot match.
Every developer at IRPR has built and shipped production software for at least 10 years. They have seen failed deployments, broken databases, and scaling crashes. That experience means your first release is stable.
You get a team that writes clean code, sets up monitoring, and documents everything. No handoff drama, no rewriting after launch. Our senior developers deliver code that lasts.
Why IRPR Is Different from Generic Dev Shops
Most agencies sell you junior developers at senior rates. We do the opposite.
Generic dev shops assign fresh graduates to your project after the sale. They bill hourly, change scope without notice, and disappear after launch. You end up with code you cannot maintain.
IRPR assigns senior engineers who have built similar products before. We give a fixed price after the Roadmap phase, and you own every line of code. No surprises, no excuses.
- Hourly billing with no cap
- Junior developers with 1-2 years experience
- Scope changes after every meeting
- No compliance knowledge (HIPAA, PCI)
- Code delivered without tests or docs
- No post-launch support
- Fixed price after Roadmap (week 2)
- Senior engineers with 10+ years each
- Scope locked in Roadmap phase
- HIPAA, PCI-DSS, SOC 2, FERPA ready
- 100% test coverage and documentation
- 2 weeks free post-launch support
How We Build with Senior Developers
Our process is designed to eliminate risk and deliver fast.
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and go/no-go gates.
In the Roadmap phase (week 2), we produce a full spec, technical design, wireframes, and a fixed price. You decide to proceed or walk away with the spec.
What Ships with Every Project
You get more than just code. These are the deliverables you can expect.
Every engagement includes source code, tests, CI/CD, and monitoring. We do not cut corners.
You own the code from day one. There is no proprietary license, no vendor lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- 100% unit test coverage for critical paths
- API documentation (Swagger/OpenAPI)
- Deployment runbook
- 1-year warranty on bugs
- 2 weeks free post-launch support
- Full code ownership

Why teams hire us.
Senior-only teams, no juniors
Every developer on your project has 10+ years of experience and has shipped at least 5 products. We do not train junior devs on your budget.
Fixed price from week 2
After the 2-week Roadmap phase, you get a fixed price for the full project. No hourly billing, no surprise charges, no scope creep.
8-12 week MVPs
Most projects ship in 8 to 12 weeks. We break the work into 2-week sprints with weekly demos so you see progress every Friday.
Full code ownership
You own the source code, design files, and documentation from day one. No licenses, no royalties, no restrictions.
99.9% uptime guarantee
We deploy with redundancy, auto-scaling, and 24/7 monitoring through Datadog. If uptime drops below 99.9%, we fix it at no cost.
HIPAA and PCI compliance built in
Our engineering team has delivered 40+ HIPAA-compliant projects and 20+ PCI-DSS projects. Compliance is not an afterthought.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
