What Senior Full Stack Product Development Consultants Deliver
We ship more than code. Every engagement includes a full product lifecycle from architecture to deployment.
Our consultants start each project with a two-week Roadmap phase. We write specs, design the database schema, and set up CI/CD pipelines with GitHub Actions. You get a fixed price quote before any development begins.
By week 12, you own a production-ready application running on AWS with 99.9% uptime. We hand over source code, documentation, and a runbook. Post-launch support keeps your product stable for 30 days.
The Difference Between IRPR and Generic Development Shops
Most agencies hire junior developers or freelancers. IRPR staffs senior engineers only and guarantees fixed pricing from day two.
Generic agencies often bill by the hour, change scope without warning, and deliver code that fails audits. We have seen it all: broken CI/CD, missing tests, and dependencies that lock you in.
IRPR works differently. We assign a senior full stack lead who stays until launch. Every project includes automated testing, code reviews, and compliance checks for HIPAA or PCI-DSS. You own everything.
- Hourly billing with no cap
- Junior developers with high turnover
- No dedicated QA
- Deliverables often miss compliance (SOC 2, HIPAA)
- Code is poorly documented
- No post-launch support
- Fixed price from the Roadmap phase (week 2)
- All senior engineers – no juniors or freelancers
- Dedicated QA on every project
- Built to HIPAA, PCI-DSS, or SOC 2 standards
- Full documentation and runbook provided
- 30 days of post-launch support included
Our Product Development Process in 4 Phases
Every engagement follows the same structured process: Idea, Roadmap, Product, Release.
Phase 1: Idea – You tell us your vision. We align on goals, user stories, and compliance needs. This takes one week.
Phase 2: Roadmap – We write technical specs, design the architecture, and give you a fixed price. You see exactly what you get before development starts.
What Ships With Every Engagement
When we finish, you own everything. No lock-in, no hidden fees.
Every project includes a full handover package. You get the source code in your own GitHub repository, a running cloud environment, and a runbook explaining how to maintain it.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Dockerized application with Docker Compose
- Staging and production environments on AWS
- Sentry error tracking configured
- Datadog monitoring dashboards
- Postman API collection
- Database schema documentation
- User-facing documentation (if applicable)
- 30 days of post-launch support via Slack

No Scope Creep
The Roadmap phase locks in exactly what we build. Any change request goes through a simple change order process with a clear price impact. No feature is added for free.
Post-Launch Support and DevOps
We provide 30 days of post-launch support including bug fixes and monitoring. After that, you can extend support monthly at a flat rate. Your product stays stable.
