Why IRPR is the Best Backend API Development Company
We have shipped 200+ backend APIs for clients in 50+ countries. Here is what that experience delivers.
Every API we build starts with a detailed Roadmap phase. In week 2, you get a fixed price, a timeline, and a tech stack decision. No surprises. No scope creep. We use Node.js, Python, Go, or Rust based on your performance needs.
Our APIs handle 10,000+ requests per second with 99.9% uptime. We include monitoring with Datadog, error tracking with Sentry, and automated load testing with k6. You get a production-ready API that scales from day one.
Generic Dev Shop vs IRPR: The Real Difference
Not all backend API development companies deliver the same result. Here is how we compare.
Generic dev shops often start coding without a clear plan. They use hourly billing, which means you pay for their learning curve. They rarely include monitoring, documentation, or CI/CD in the price.
IRPR gives you a fixed price after a 2-week Roadmap. We include everything: source code, CI/CD, monitoring, API docs, and a 30-day warranty. You own the code. You can deploy anywhere.
- Hourly billing with no cap
- No Roadmap phase
- No monitoring included
- No CI/CD pipeline
- No API documentation
- No compliance expertise
- Fixed price after 2-week Roadmap
- Full source code ownership
- Datadog monitoring included
- GitHub Actions CI/CD included
- OpenAPI docs included
- HIPAA, PCI-DSS, SOC 2 ready
Our Backend API Development Process
We follow a 4-phase process that delivers a production-ready API in 8-12 weeks.
Phase 1 is the Idea phase where we define the API contract, data model, and tech stack. Phase 2 is the Roadmap where we give you a fixed price and timeline. Phase 3 is Product where we build and test. Phase 4 is Release where we deploy and monitor.
Each phase has clear deliverables. You see progress every week. No black boxes. No surprises.

You get everything you need to run and maintain the API yourself. No vendor lock-in. No recurring fees.

- OpenAPI 3.0 documentation
- Postman collection for testing
- Datadog monitoring dashboard
- Sentry error tracking

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.
Senior engineers only
Every engineer on your project has 8+ years of experience. No juniors, no offshore teams, no learning on your dime. Our average engineer has shipped 15+ production APIs.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Not 6 months. Not a year. We use proven frameworks and templates to accelerate development without cutting corners.
Full code ownership
You own 100% of the source code. No licensing fees, no platform lock-in, no recurring royalties. Deploy anywhere: AWS, GCP, Azure, or your own servers.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and GDPR compliance into the API from day one. No retrofitting. No expensive audits after launch. We have done it 50+ times.
Post-launch support
Every project includes a 30-day warranty with bug fixes and monitoring. We also offer ongoing maintenance at a fixed monthly rate. You are never left alone after launch.
