Why You Need a Professional Backend App Development Vendor
A vendor that builds backend systems on time, on budget, and compliant from day one.
IRPR has shipped over 200 backend projects for clients across 50 countries. Our average delivery timeline is 12 weeks, with 98% of projects delivered on schedule. We use serverless architectures on AWS Lambda to reduce hosting costs by 40%.
Every backend system we build includes automated monitoring with Datadog, error tracking with Sentry, and real-time logs with CloudWatch. We provide a full security audit report before launch.
Professional Backend App Development Vendor vs Generic Dev Shop
The difference between a dedicated backend vendor and a generic agency is the difference between a production system and a prototype.
Generic dev shops bill by the hour and have no fixed timeline. They often deliver incomplete code with no testing or documentation. After launch, you are on your own.
IRPR provides a fixed price from week 2 of the Roadmap phase. We deliver a fully tested backend with CI/CD, 99.9% uptime SLA, and 3 months of maintenance. Code ownership is yours from day one.
- Hourly billing with no cost cap
- No committed delivery date
- Code ownership not defined
- Manual deployment without CI/CD
- No compliance or security audit
- No post-launch support
- Fixed price from Roadmap (week 2)
- 12-week delivery committed
- Full code ownership from day 1
- Automated CI/CD pipeline on GitHub Actions
- HIPAA/PCI/SOC2 built-in
- 3 months of maintenance included
How IRPR Delivers Your Backend Project
A structured process from discovery to production with milestones and deliverables at every stage.
We start with a 2-week Roadmap phase where we define architecture, data model, API contracts, and a fixed-price quote. No surprises. After approval, we move to iterative development.
Each sprint ends with a working deployment. We use feature flags and blue-green deployments to minimize risk. By week 10, the system is in beta; by week 12, it is production-ready.
What Ships with Your Professional Backend App Development
Every backend project includes these deliverables by default. No optional extras - they are part of the standard package.
When IRPR completes a project, you get more than just code. You get a complete system that is production-ready, secure, and maintainable by your team.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking
- Postman API documentation
- Docker containers for all services
- Load test results (k6 or Artillery)
- Security audit report
- Deployment playbook
- Infrastructure as code (Terraform or CDK)
- 3 months of production support

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
12-week delivery guarantee
We deliver most backend projects in 12 weeks. Our record is 8 weeks for a mid-size API. If we miss the deadline, we discount the final payment by 10%.
Compliance built in, not bolted on
HIPAA, PCI-DSS, and SOC 2 are part of our standard build process. We use encryption at rest and in transit, logging, and access controls by default. No retrofitting after the fact.
Full code ownership from day one
You own everything we produce: source code, documentation, test suites. There is no license fee, no vendor lock-in. Your team can take over maintenance immediately after launch.
Senior engineers only
Every IRPR engineer has 10+ years of experience. We do not hire juniors or outsource to low-cost countries. Your project is led by a staff engineer who will be available during your business hours.
Post-launch support included
We include 3 months of production support with every backend project. This covers bug fixes, performance tuning, and deployment assistance. After that, we offer a fixed-price retainer at $5K/month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
