Senior SaaS Platform Development Developers With a Real Track Record
We are not a staffing agency. We are a studio that ships working software.
IRPR has delivered over 200 products across 50 countries. Our senior engineers average 10+ years building SaaS platforms. Every line of code is reviewed by a second senior engineer before merge.
We track every project against a fixed scope defined in week 2. The average project finishes within 5% of the budget. Clients get full source code, CI/CD pipelines, and infrastructure as code.
Why Generic Dev Shops Fail at SaaS Platform Development
Most agencies promise senior developers but deliver juniors, hourly billing, and no compliance.
IRPR assigns only senior engineers with 8+ years of backend experience. We do not use body shops or outsource teams. Our contracts are fixed price from day one.
Every SaaS platform we build meets SOC 2 controls by default. We also support HIPAA, PCI-DSS, and GDPR. Your customers get a secure platform from launch.
- Junior developers working remotely
- Hourly billing with no cap
- No compliance knowledge
- Code quality not reviewed
- No infrastructure automation
- Ownership unclear
- Senior engineers with 8+ years
- Fixed price per project
- SOC 2, HIPAA, PCI-DSS ready
- Paired code reviews on every PR
- Terraform CI/CD out of the box
- Full IP and code ownership
Our Process for Building a Senior SaaS Platform
From idea to production in 4 phases. Each phase has a clear deliverable and fixed timeline.
Phase 1 (Idea): We validate assumptions and pick the best tech stack for your use case. Phase 2 (Roadmap): We produce a detailed roadmap with wireframes, user stories, and a fixed price.
Phase 3 (Product): Engineers build the platform in bi-weekly sprints. You see working software every 14 days. Phase 4 (Release): We deploy to production, set up monitoring, and run a one-month handoff.
What Ships When You Hire Senior SaaS Platform Development Developers
Every engagement includes these deliverables. No hidden fees or surprises.
We treat your project like a product. You get the same infrastructure a funded startup would build in year two, delivered in your first month.
All source code is on GitHub under your account. We never hold code hostage. The infrastructure is yours to manage or to have us support ongoing.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automated tests
- Infrastructure as code using Terraform on AWS
- Sentry error tracking and Datadog monitoring
- Stripe or Braintree payment integration
- SOC 2 compliant logging and access controls
- User authentication with Auth0 or Cognito
- API documentation with Swagger/OpenAPI
- Load tested to handle at least 1000 concurrent users
- One month of post-release support and bug fixes
