Senior SaaS Development VendorDevelopment Vendor
We build SaaS platforms that scale. Fixed price, 12-week MVP delivery, senior engineers only.
IRPR is a senior SaaS development vendor that builds multi-tenant platforms, API-first backends, and subscription billing systems. We use Next.js, React, Node.js, Python, PostgreSQL, and AWS to ship production-ready SaaS products.
Every project starts with a 2-week Roadmap phase that defines the full scope and fixed price. Typical MVP delivery is 12 weeks. Projects range from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance from day one.
We work with founders who need a technical co-founder replacement, CTOs scaling their engineering capacity, product managers launching new verticals, and enterprises migrating legacy systems to SaaS. Each gets a dedicated team of senior engineers with no junior overhead.

Why choose a senior SaaS development vendor
Building a SaaS product requires deep architecture decisions that impact scaling, billing, and compliance.
A junior team might pick the wrong database or skip multi-tenancy until it's too late. IRPR's senior engineers design for scale from day one. We use PostgreSQL schemas for tenant isolation, Redis for rate limiting, and AWS ECS for auto-scaling. Every decision is documented in the Roadmap phase (week 2).
We have shipped 200+ SaaS products across 50 countries. Our average MVP timeline is 12 weeks. 98% of projects deliver on time. We only hire engineers with 8+ years of experience. No juniors, no offshore teams, no micromanagement.
The difference between IRPR and a generic dev shop
Not all development vendors are built the same. Here is what sets IRPR apart.
Generic dev shops often assign junior developers to save costs. They use hourly billing that encourages slow work. They avoid compliance because it adds complexity. They hand over code with no documentation or deployment scripts.
IRPR assigns senior engineers only. We use fixed pricing from the Roadmap phase. We build for HIPAA, PCI-DSS, and SOC 2 from day one. Every project ships with source code in your repo, CI/CD pipeline, and full documentation.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- No compliance expertise
- Code delivered without tests
- No CI/CD or deployment scripts
- Handoff with no documentation
- Senior engineers with 8+ years experience
- Fixed price from Roadmap phase (week 2)
- HIPAA, PCI-DSS, SOC 2 built in
- 100% test coverage for core paths
- CI/CD pipeline on GitHub Actions
- Full architecture documentation
How IRPR builds your SaaS product
Our process from idea to release is structured, transparent, and fast.
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price. No scope creep, no surprises.
The Roadmap phase (week 2) produces a full architecture document, database schema, API design, and timeline. The Product phase (weeks 3-12) builds the MVP in sprints with weekly demos. The Release phase handles deployment, monitoring, and handoff.
