Why hire a senior full stack software development agency
You need experienced engineers who understand architecture, security, and delivery. Not junior coders learning on your dime.
IRPR was founded by engineers with over 15 years of experience each. We only hire senior developers who have shipped production systems at scale. Every engineer on your project has at least 5 years of full stack experience, usually more than 10.
We assign a staff-level engineer as your lead architect. They define the tech stack, set up CI/CD with GitHub Actions, and enforce code reviews. You get weekly demos and a shared Jira board so nothing is hidden.
The difference between IRPR and other agencies
Most agencies sell you junior developers at senior rates. IRPR only hires senior engineers and charges a fixed price.
Generic development shops often staff projects with 2-3 junior or mid-level developers supervised by one senior. You pay hourly and watch the budget burn. The code quality suffers, technical debt piles up, and you often need to rebuild after launch.
IRPR sends a team of senior engineers only. Your lead architect has shipped products at Google, Amazon, or top startups. We quote a fixed price during the Roadmap phase (week 2) so you know the cost before we write any production code.
- Junior developers doing most of the work
- Hourly billing with weekly invoices
- Vague timelines that slip by months
- No code quality standards
- You own nothing until final payment
- Communication goes through an account manager
- Staff-level engineers with 10+ years experience
- Fixed price agreed before coding begins
- 8-12 week delivery documented in Roadmap
- Automated testing and code reviews every sprint
- Source code in your repo from day one
- Direct Slack channel with the lead engineer
Our process to build your full stack product
Four phases take you from idea to deployed product with no surprises.
Every engagement starts with a 1-2 week Discovery phase where we understand your market, users, and technical requirements. We produce a detailed spec that becomes the blueprint for the project.
Then the Roadmap phase defines the full scope, tech stack, and fixed price. Once you approve, we move into Product development where we build in 2-week sprints with continuous deployment. The Release phase includes load testing, security audit, and production monitoring setup.
What ships with your project by default
You own everything. No black boxes, no vendor lock-in, no surprise fees.
Every project includes the production-ready codebase, infrastructure scripts, and monitoring tools. We don't hold your code hostage. You get access to everything from the first commit.
We set up CI/CD pipelines that run tests, build containers, and deploy automatically. You can take over development yourself or hire another team without friction.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Docker
- Automated unit and integration tests (Jest, Cypress)
- Staging and production environments on AWS
- Database schema and migration scripts
- API documentation (Swagger/OpenAPI)
- Sentry error tracking and Datadog monitoring
- Admin dashboard for key operations
- User authentication (Auth0 or custom JWT)
- Deployment runbook and architecture diagram

Why teams hire us.
Staff-level engineers only
Every developer on your project has 10+ years of full stack experience. We don't use junior developers or offshore interns. Your lead architect has shipped products at companies like Google and Amazon.
Fixed price, not hourly
We give you a fixed price during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of production code.
8-12 week MVP delivery
We ship a working, production-ready MVP in 8 to 12 weeks. Our average is 10.5 weeks across 200+ projects. We built this speed by using battle-tested templates and senior engineers who don't need hand-holding.
Full ownership with no lock-in
You own the source code, infrastructure, and IP from day one. We host your code in your GitHub repository, deploy to your AWS account, and hand over all credentials. No vendor lock-in, no monthly maintenance fees unless you want ongoing support.
Compliance built in (HIPAA, SOC 2, PCI-DSS)
We design systems with compliance from the start. Our engineers have built HIPAA-compliant telemedicine apps, SOC 2 compliant SaaS platforms, and PCI-DSS Level 1 payment systems. We document everything for auditors.
Direct communication with engineers
No account managers, no project managers that don't code. You talk directly to the lead engineer on Slack or a weekly video call. We give you a Jira board and a live demo environment so you see progress every day.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
