Senior Custom SaaS Development TeamSaaS Development
We build custom SaaS platforms for B2B and B2C markets. Our senior engineers deliver production-ready MVPs in 12 weeks with fixed pricing.
IRPR builds custom SaaS platforms using PostgreSQL, Node.js, React, and AWS. Our senior custom SaaS development team handles multi-tenant architecture, subscription billing with Stripe, and CI/CD pipelines on GitHub Actions.
We deliver production-ready MVPs in 8-12 weeks with fixed pricing from $80K to $250K. Compliance includes SOC 2, HIPAA, and PCI-DSS where needed. You get full code ownership and a dedicated product manager.
Companies hire IRPR when they need a senior custom SaaS development team to replace a stalled project, launch a new vertical SaaS product, or migrate from a legacy monolith. Typical buyers are CTOs, product directors, and SaaS founders who have raised seed or Series A funding.

Why a senior custom SaaS development team matters
A junior team wastes time on rework. Senior engineers ship clean, scalable code from day one.
IRPR's senior custom SaaS development team averages 10+ years of experience per engineer. We have shipped over 200 SaaS products across 50 countries, with 98% on-time delivery.
Every project starts with a Roadmap phase where we define the MVP scope, architecture, and compliance needs. You get a fixed price before any code is written.
The difference between generic SaaS dev and senior engineering
Many agencies build SaaS apps that break at scale. IRPR engineers design for growth.
Generic dev shops assign junior developers, use hourly billing, and deliver code without CI/CD or tests. They often disappear after launch.
IRPR's senior custom SaaS development team gives you a fixed price, a dedicated PM, full code ownership, and 30 days of post-launch support.
- Hourly billing that balloons without warning
- Junior developers with little oversight
- No dedicated product manager
- No CI/CD pipeline set up
- No post-launch support included
- You get limited access to source code
- Fixed price from $80K after Roadmap phase
- Senior engineers only, average 10+ years
- Dedicated product manager on every project
- GitHub Actions CI/CD from day one
- 30-day post-launch support included
- Full code ownership in your private GitHub repo

Senior engineers only
Every developer has 10+ years experience. We never outsource to juniors or offshore vendors. Our team includes specialists in PostgreSQL, React, and AWS.
Product manager included
A dedicated PM runs weekly demos, manages sprints, and keeps you informed. No need to manage the team yourself. You get direct access to the PM via Slack.
Full code ownership
Source code is in your GitHub repository from day one. You own everything we build. No lock-in, no licensing fees, no ongoing royalties.
Compliance built-in
We handle SOC 2, HIPAA, and PCI-DSS requirements during development. No afterthought security. Our senior custom SaaS development team includes compliance in the architecture.
Post-launch support
30 days of bug fixes and tweaks after launch. We don't disappear once the MVP ships. You can extend support into a quarterly retainer if needed.
