Senior Custom Software Development ConsultantsDevelopment Consultants
You get a team of senior engineers who ship production software in 8-12 weeks. Fixed price, no hourly billing, no surprises.
IRPR provides senior custom software development consultants who build web apps, mobile apps, AI chatbots, and SaaS platforms. We use React, Next.js, Node.js, Python, PostgreSQL, and AWS to ship production-grade software every time.
Every project starts with a 2-week Roadmap phase where we scope the work and give you a fixed price. MVPs ship in 8-12 weeks. Typical projects range from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
We work with CTOs who need to launch a product without hiring a full in-house team. Startup founders who want a technical co-founder without equity. And enterprise VPs who need a senior team to build a compliant, scalable system on a fixed timeline.

What senior custom software development consultants deliver
Every engagement includes a fixed scope, a fixed price, and a fixed timeline.
IRPR assigns a team of 2-4 senior engineers to your project. Each engineer has 10+ years of experience and has shipped at least 10 production applications. You get a dedicated project manager and a QA engineer as well.
We start with a 2-week Roadmap phase where we define the architecture, tech stack, user stories, and a fixed price. No ambiguity. No scope creep. You know exactly what you are getting and when.
How IRPR differs from other software consultants
Most agencies sell you junior developers and bill by the hour. We do the opposite.
Generic dev shops hire cheap junior developers and charge you for their learning curve. They bill hourly, so you never know the final cost. They avoid compliance work because it is hard.
IRPR only hires senior engineers with 10+ years of experience. We give you a fixed price after a 2-week Roadmap. We handle HIPAA, PCI-DSS, and SOC 2 compliance. You get the code, the CI/CD pipeline, and full ownership.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- No compliance expertise
- Scope creep on every project
- No CI/CD or DevOps included
- Code quality varies wildly
- Senior engineers with 10+ years experience
- Fixed price after 2-week Roadmap
- HIPAA, PCI-DSS, SOC 2 compliant
- Fixed scope with change control process
- CI/CD pipeline on GitHub Actions included
- Code review and automated testing on every project
Our process for senior custom software development consulting
Four phases. No surprises. You stay in control the whole time.
Every engagement follows the same proven framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go decision point.
You are never locked in. After the Roadmap, you can walk away with the full spec and architecture. Most clients continue because they see exactly what they will get.
