Senior Custom Software Development Services: The Numbers That Matter
Our track record is built on real deliveries, not promises.
IRPR has shipped over 200 custom software products to clients in more than 50 countries. Every project is staffed exclusively with senior engineers who have 8+ years of average experience. No junior or mid-level developers are assigned to your codebase.
Our average MVP delivery is 12 weeks from Roadmap approval, with 98% of projects delivered on time. We maintain a 99.9% uptime SLA across all production deployments. Pricing is fixed up front during the Roadmap phase, typically between $80K and $250K per project.
Generic Dev Shop vs Senior Custom Software Development Services
Not all software development services are equal. Here is how IRPR stands apart.
Many agencies assign junior developers to your project to save costs. That leads to slow progress, quality debt, and missed deadlines. You end up paying for both the junior's learning curve and the senior's rework.
At IRPR, every engineer is a senior with 8+ years of experience. We work on fixed price contracts, so you know exactly what you pay. Our Roadmap phase (week 2) locks scope and price before any large code commit.
- Assigns junior and mid-level developers
- Hourly billing with no cap
- Scope creep inflates costs by 40%+
- No compliance expertise
- Slow onboarding (4+ weeks)
- Code quality varies widely
- Senior engineers only (8+ yrs avg)
- Fixed price determined in Roadmap phase
- Scope controlled through weekly demos
- HIPAA, PCI-DSS, SOC 2 built in
- Kickoff within 1-2 weeks
- Code reviews and automated testing
How Our Senior Custom Software Development Process Works
A four-phase process designed to de-risk your investment and accelerate delivery.
Every project follows our Idea -> Roadmap -> Product -> Release framework. The Roadmap phase costs a flat fee and produces a detailed specification, wireframes, tech architecture, and a fixed price quote. If you choose not to proceed after Roadmap, you keep all the deliverables.
Once you approve the Roadmap, the Product phase begins. Our senior engineers build your software in 8-12 weeks using agile sprints, daily standups, and weekly demos. Release includes deployment to your cloud environment, documentation, and a handoff call.
What Ships With Every Senior Custom Software Project
Every engagement includes these deliverables as standard, not optional extras.
We believe in full transparency and zero lock-in. You get everything you need to run, modify, and scale the software yourself if you choose. No proprietary frameworks, no hidden dependencies.
All deliverables are backed by our 30-day post-launch warranty. If something breaks due to our code, we fix it at no charge. After that, you can extend support on a monthly retainer or go independently.
- Full source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as Code (Terraform/AWS CDK)
- Sentry error tracking and Datadog monitoring
- Deployment to your own AWS/GCP/Azure account
- User documentation (technical and end-user)
- Admin panel and API documentation (Swagger/OpenAPI)
- Performance load test report (k6) for key endpoints
- 30-day post-launch warranty with 4-hour SLA response
- One handoff call and one knowledge transfer session

Every developer on your project has 8+ years of experience and has shipped at least 5 production applications. IRPR does not hire juniors or mid-level engineers for client work.
8-12 Week MVP Delivery
From Roadmap approval to production release, your MVP ships in 8 to 12 weeks. We use agile sprints, weekly demos, and automated testing to maintain velocity without quality trade-offs.
Full Code Ownership

Compliance Built In, Not Bolted On
We have delivered HIPAA, PCI-DSS, SOC 2, and FERPA compliant applications. Compliance is part of the architecture from day one, not an afterthought added during audit.
