Why You Need Senior Custom SaaS Development Developers
Building a SaaS product is different from building a website. It needs multi-tenancy, billing, user management, and CI/CD from day one.
IRPR's senior custom SaaS development developers have shipped over 200 SaaS products. Every project starts with a Roadmap phase where we define the schema, API contracts, and deployment architecture. You get a fixed price and a timeline before any code is written.
We use AWS ECS with auto-scaling, PostgreSQL with connection pooling, and Next.js for the frontend. Every deployment includes Sentry error tracking, Datadog monitoring, and automated backups. Your SaaS stays up with 99.9% uptime.
How IRPR Compares to Other Dev Shops
Most agencies bill hourly and let scope creep blow the budget. IRPR works differently.
We learned from 200+ projects that fixed pricing and a clear Roadmap phase produce better outcomes. You know the cost and timeline before we build anything. No surprises, no hourly tracking.
Every senior custom SaaS development developer at IRPR has 8+ years of experience. We don't outsource. We don't use junior devs. You work directly with the engineers building your product.
- Bills hourly, so you pay for their learning curve
- No dedicated QA; bugs reach production
- Uses whatever stack the lead dev knows
- No CI/CD pipeline; deploys manually
- No compliance readiness (HIPAA, SOC 2)
- Code ownership is unclear
- Fixed price from the Roadmap phase (week 2)
- Automated testing and QA in every sprint
- Uses Next.js, Node.js, PostgreSQL, AWS
- CI/CD on GitHub Actions with staging and production
- HIPAA and SOC 2 compliance built in from day one
- You own the source code and all IP
Our Process for Building Your SaaS
We follow a four-phase process that de-risks your project and delivers a production-ready product.
Every phase has a clear deliverable. You see progress every week. No black boxes.
The Roadmap phase costs $8K and includes the full spec, wireframes, and a fixed-price contract for the build. If you don't like the Roadmap, you walk away with the spec.
