Why a Senior Custom Software Development Agency Matters
Senior engineers make your project faster and more reliable.
IRPR hires only engineers with 7+ years of experience. They have built production systems for companies like Netflix and Stripe. This means fewer bugs, faster delivery, and better architecture decisions.
We also enforce code reviews, automated testing, and security audits on every project. The result is a 98% on-time delivery rate and 99.9% uptime across all products.
The Difference Between Junior Teams and Senior Engineers
Not all development agencies deliver the same quality.
Many agencies hire junior developers to keep rates low. This leads to tech debt, missed deadlines, and security gaps. IRPR takes a different approach.
We staff every project with senior engineers who handle all details from architecture to deployment. The cost is higher per hour but total project cost is lower because rework is avoided.
- Hire junior developers at lower rates
- Charge hourly with no cap
- No source code ownership clause
- Manual QA or no QA
- Scope creep without change order
- No compliance expertise
- Senior engineers only (7+ years experience)
- Fixed price from the Roadmap phase
- Full source code ownership
- Automated CI/CD and Sentry monitoring
- HIPAA/PCI compliance built-in
- 98% on-time delivery
How We Build Your Custom Software
Our process is transparent and predictable from day one.
Every project follows a four-phase process. This ensures no surprises and clear milestones. You see progress every week.
Phase one is a 2-week discovery to understand your users and market. Phase two produces a fixed-price Roadmap. Then we build and ship.
What Ships With Every Project
You get more than just code. Every deliverable is production-ready.
IRPR includes a standard set of deliverables that most agencies charge extra for. Everything is included in the fixed price.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Docker containers for local and production
- API documentation using Swagger/OpenAPI
- Admin dashboard with user management
- Analytics dashboard with Mixpanel or PostHog
- Load testing results with k6
- SEO optimization for meta tags and structured data
- 1-year post-launch support SLA (email and Slack)
