Senior Custom SaaS Development ConsultantsDevelopment Consultants
We build custom SaaS platforms for B2B and B2C. Fixed price, 8-12 week delivery, senior engineers only.
IRPR is a senior custom SaaS development consultancy. We build scalable multi-tenant SaaS platforms using TypeScript, Node.js, React, PostgreSQL, and AWS. Every project starts with a fixed-price Roadmap phase (2 weeks) to define scope and architecture.
We ship an MVP in 8-12 weeks. Pricing ranges from $80K to $250K depending on complexity. We handle compliance (SOC 2, HIPAA, PCI-DSS) and production deployment with CI/CD on GitHub Actions.
Our clients include B2B SaaS founders who need a technical co-founder, enterprise innovation teams that need to launch internal SaaS tools, and startups that have a prototype but need production-ready architecture. We also work with agencies that need white-label SaaS development.

Why hire senior custom SaaS development consultants at IRPR?
We bring deep SaaS architecture experience and a track record of 200+ shipped products.
Our team has built SaaS products for startups and Fortune 500 companies across 50+ countries. We use proven patterns: multi-tenant isolation, event-driven microservices, and CI/CD pipelines that push code to production daily.
Every project is led by a senior engineer with 10+ years of experience. You get a dedicated lead who stays with your project from Roadmap to Release. No junior developers, no offshore juggling.
How IRPR differs from generic software development shops
Most agencies promise senior talent but staff projects with juniors. We don't.
We have seen projects fail because of scope creep, unclear requirements, and a lack of SaaS-specific architecture. Our fixed-price Roadmap eliminates that risk in the first 2 weeks.
After the Roadmap, we lock in a fixed price for the entire build. No hourly billing, no surprise invoices. We ship the MVP in 8-12 weeks, and you own 100% of the code.
- Hourly billing with unpredictable budget
- Junior developers doing most of the work
- No dedicated technical lead
- Generic boilerplate code
- No compliance experience (SOC 2, HIPAA, PCI-DSS)
- Handoff with no post-launch support
- Fixed-price Roadmap + fixed-price build
- Senior engineers only (12-year average)
- One dedicated lead engineer per project
- Custom architecture designed for SaaS scalability
- Built-in compliance for SOC 2, HIPAA, PCI-DSS
- Sentry monitoring, CI/CD pipeline, and 30-day post-launch support
Our 4-phase process for senior custom SaaS development
We use the Idea - Roadmap - Product - Release framework on every project.
Each phase has a clear deliverable and a fixed duration. This eliminates guesswork and keeps the project on schedule.
You are involved in every sprint review. We use linear.app for task tracking and Slack for daily communication. No black boxes.
What ships with every SaaS project from IRPR
You get more than just code. Every delivery includes production-ready infrastructure and documentation.
All projects include a fully automated CI/CD pipeline, monitoring, and a deployment playbook. You can deploy changes yourself on day one.
We also provide a comprehensive handover document covering architecture decisions, environment variables, and runbooks for common operations.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- AWS infrastructure as code (Terraform or CDK)
- Sentry error tracking and performance monitoring
- Unit and integration tests (Jest, Cypress)
- API documentation (Swagger/OpenAPI)
- Admin panel for user and billing management
- Sprint retrospectives and handover documentation
- 30-day post-launch support with priority response time
- Full ownership of all IP and code

Senior engineers only, no junior staff
Our engineers average 12 years of experience. We never staff projects with juniors or use offshore code factories. Your lead engineer stays with you from Roadmap to Release.
Proven SaaS architecture patterns
We have built multi-tenant systems handling 100K+ users. We use database-per-tenant or schema-per-tenant patterns, queue-based load leveling, and autoscaling on AWS. Our reference architecture is documented in every project.
Built-in compliance from day one
We have delivered SaaS products that passed SOC 2 Type II, HIPAA, PCI-DSS, and FERPA audits. Compliance is part of the architecture, not an afterthought. We provide evidence packages for your auditor.
Full code ownership and no lock-in
You own every line of code. We deploy to your AWS account using Terraform. You can take the code to any team after we finish. No proprietary frameworks, no hidden dependencies.
Transparent sprint cycles and daily communication
We use 2-week sprints with a live demo at the end of each sprint. You have direct Slack access to the entire team. Linear.app shows exactly what we are working on, every day. 98% of our projects ship on time.
