Senior SaaS Development Services: What We Ship
Every project delivers production-ready code, full testing, and deployment scripts.
Our senior SaaS development services include architecture design, multi-tenancy setup, stripe integration, and SOC 2 compliance documentation. You get a working platform in 12 weeks, not 12 months.
We use Terraform for cloud infrastructure, Cypress for end-to-end tests, and Sentry for error monitoring. The team writes every line of code in your private GitHub repo.
How We Differ from Generic Dev Shops
Not all senior SaaS development services are equal. Here is why IRPR delivers.
Generic agencies assign junior developers to your SaaS project. They charge hourly, which means you pay for their learning curve. IRPR assigns senior engineers only -- every team member has 8+ years of production experience.
We deliver a fixed-price proposal after a 2-week Roadmap phase. No hourly billing. No scope creep. You know the total cost before we write a single line of code.
- junior developers train on your dime
- hourly billing with no cap
- multi-tenancy as an afterthought
- no compliance documentation
- code dumps without CI/CD
- scope creep each sprint
- senior engineers only, avg 10 years experience
- fixed price from Roadmap phase
- multi-tenant architecture from day one
- SOC 2 / HIPAA / PCI compliance included
- CI/CD pipeline on GitHub Actions with staging
- strict scope control with weekly demos
Our 4-Phase Senior SaaS Development Process
From idea to production in 14 weeks or less.
We break your SaaS project into four distinct phases. Each phase ends with a working deliverable you can review and test.
You stay in control. We provide weekly demos, a real-time dashboard, and a dedicated Slack channel for questions.
