Senior backend app development partnerbackend app
We build fast, secure backends that scale. Fixed price, no surprises, and you own the code.
IRPR is a senior backend app development partner. We build backends using Go, Node.js, Python, PostgreSQL, MongoDB, and cloud infrastructure on AWS, GCP, or Azure. Every engineer has 10+ years experience.
We ship production-ready backends in 8-12 weeks for a fixed price typically between $80K and $250K. Our teams handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get code in your repo, CI/CD pipelines, monitoring, and documentation.
CTOs hire us when their startup needs a scalable backend fast. Product managers hire us to ship their MVP without hiring a full team. VCs and accelerators refer founders who need a reliable technical partner from day one.

Senior backend team results
Hundreds of clients trust IRPR as their senior backend app development partner.
We have shipped over 200 backend products across 50 countries. Our engineers average 12 years of experience. Projects start with a 2-week Roadmap phase where we define the architecture, data model, and API contract.
98% of our projects ship on time. We use fixed pricing so you know the cost from week 3. Post-launch, we provide 30 days of free support and monitoring.
IRPR vs generic dev shops
Not all backend partners are equal. Here is how IRPR compares.
Generic dev shops assign junior developers who learn on your dime. They bill hourly and extend timelines when things get hard. You get code that breaks and no support.
IRPR assigns senior engineers only. We work on fixed price so we are motivated to ship fast. You get ownership of the code, automated testing, and 30 days free support.
- Junior developers with 2 years experience
- Hourly billing with no cap
- No compliance experience
- Code not documented or tested
- Slow communication via account managers
- No post-launch support
- Senior engineers with 10+ years each
- Fixed price from week 3
- HIPAA, PCI-DSS, SOC 2, FERPA certified
- Full test coverage and documentation
- Direct Slack access to engineers
- 30 days free monitoring and fixes
How we build your backend
Our 4-phase process for every senior backend app development project.
Phase 1: Idea. We do a free discovery call to understand your requirements, timeline, and budget. No commitment needed.
Phase 2: Roadmap. In 2 weeks we produce a detailed Roadmap document with data model, API design, tech stack, and fixed price. You pay $5K for this phase, which is applied to your project.
What ships with your backend
Every project includes these deliverables by default.
We do not just write code. We ship a production-ready system with all the tooling you need to run it yourself.
Everything is automated. You get deployment scripts, monitoring alerts, and a runbook for on-call engineers.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- PostgreSQL or MongoDB database schema
- RESTful API documentation (OpenAPI/Swagger)
- Unit and integration tests with >80% coverage
- Deployment to AWS, GCP, or Azure
- Sentry error tracking integrated
- Datadog or Grafana dashboards for monitoring
- Admin dashboard for data management
- Security audit and compliance checklist

After the 2-week Roadmap, we quote a fixed price for the entire build. No hourly billing means no surprises. You know the cost before we write a line of code.
Compliance is built in, not bolted on
We have built backends that passed HIPAA, PCI-DSS, SOC 2, and FERPA audits. We include compliance requirements in the Roadmap and test against them in every sprint.
You own the code and infrastructure
All code is in your GitHub repo from day one. We deploy to your AWS/GCP/Azure account. You can take over at any time with no lock-in.
Fast kickoff and predictable timeline
We can start within 1-2 weeks of signing. The build phase runs 8-12 weeks. We ship on time 98% of the time.
30 days free support after launch
We monitor your backend for 30 days post-release. Fixes for bugs found in the first month are included at no extra cost.
