Custom SaaS Development DevelopersDevelopers
Senior engineers build your SaaS from idea to launch in 12 weeks. Fixed price, full ownership, no surprises.
IRPR builds custom SaaS products from scratch. We use Next.js for frontends, Ruby on Rails and Python for backends, and PostgreSQL or MongoDB for data. Every product gets a dedicated senior engineer who writes all the code and ships it to your repo.
A typical MVP ships in 8-12 weeks. Fixed price ranges from $80,000 to $250,000 depending on features and compliance needs. We handle HIPAA for healthcare, PCI-DSS for payments, and SOC 2 for enterprise SaaS.
Founders who need a launch-ready SaaS in 3 months hire us. Enterprises building internal platforms or customer-facing portals hire us. Tech firms needing multi-tenant architecture, API integrations, and scalable infrastructure hire us because we deliver production code, not prototypes.

Custom SaaS development developers deliver production code, not prototypes
You get a working SaaS product with real users, real payments, and real infrastructure.
IRPR's senior engineers write every line of code. We ship React frontends on Vercel, Rails APIs on AWS, and PostgreSQL databases on RDS. Your SaaS handles auth with Auth0, payments with Stripe, and monitoring with Sentry and Datadog.
Every project starts with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. You approve the plan before we write any code. After that, we build in 2-week sprints and demo every feature before it ships.
The difference between generic dev shops and custom saas development developers
Most dev shops build a demo and disappear. IRPR builds a product that scales.
Generic shops use junior developers, copy-paste code, and skip testing. They bill by the hour and hand you a codebase with tech debt. You end up paying more for maintenance than the original build.
IRPR assigns one senior engineer per project. We write tests, use CI/CD pipelines, and enforce code reviews. Every product ships with a deployment guide, infrastructure as code (Terraform), and 30 days of post-launch support included.
- bills hourly with no cap
- uses junior developers with little oversight
- ships without automated tests
- hands over code with no documentation
- no compliance experience (HIPAA, PCI-DSS)
- disappears after final payment
- fixed price from $80K to $250K
- senior engineers with 10+ years experience
- 95%+ test coverage with RSpec and Jest
- 30 days free post-launch support
- HIPAA, PCI-DSS, SOC 2 compliant by default
- full ownership of source code and IP
How custom saas development developers build your product in 4 phases
Every project follows a repeatable process from idea to release.
Phase 1: Idea validation. We map your workflows, define user stories, and choose the right data model. Phase 2: Architecture design. We draw system diagrams, choose services (AWS, Stripe, SendGrid), and set up the repo with CI/CD.
Phase 3: Build sprints. The engineer writes code in 2-week sprints. You see working features every 14 days. Phase 4: Release. We deploy to production, configure monitoring, and hand over admin access.
What ships when you hire custom saas development developers
You get a complete product, not a prototype.
Every project delivers production-ready code running on real infrastructure. You get the source code in your own GitHub repo, a CI/CD pipeline, error tracking, and performance monitoring.
We also include a deployment runbook, database backups, and a list of all third-party services with credentials. Nothing is hidden. You can hand the project to any team tomorrow.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or CircleCI
- Stripe integration for payments with test mode
- Auth0 or Clerk for authentication
- Sentry error tracking with alerts
- Datadog or New Relic performance monitoring
- Daily database backups to S3
- Deployment runbook with step-by-step instructions
- 30 days post-launch support via Slack
- Full ownership of all IP and code

Why teams hire us.
Fixed price, not hourly
Every custom SaaS project gets a fixed quote in the Roadmap phase. No hourly billing, no surprise invoices. If the scope changes, we re-quote up front. 98% of projects finish within the original budget.
Senior engineers only
IRPR does not hire juniors. Every engineer has 10+ years of experience building SaaS products. They have shipped production apps used by millions of users. Your project gets a dedicated engineer, not a team of interns.
Full ownership of code and IP
You own every line of code we write. After the project, we transfer the repo to you and delete our copies. No licensing fees, no lock-in. You can hire any developer to maintain it tomorrow.
Compliance built in from day one
Healthcare projects follow HIPAA rules (encryption at rest, audit logs, BAA). Payment projects meet PCI-DSS Level 1. Enterprise SaaS follows SOC 2 controls. We configure compliance in the Roadmap phase, not as an afterthought.
Start in 1-2 weeks
After you book a call, we schedule the Roadmap phase within 7 days. We work async with daily overlap hours for US and European time zones. Most projects start coding by the end of the second week.
Post-launch support included
Every project includes 30 days of free post-launch support. We fix bugs, answer questions, and help with minor changes. After that, you can buy support blocks or transition to an internal team. No forced retainers.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
