Expert Backend API Development VendorBackend API
Your backend API must be fast, secure, and ready to scale. IRPR delivers production-grade APIs with 99.9% uptime and full code ownership.
IRPR builds backend APIs using Node.js, Python, and Go. We design RESTful and GraphQL endpoints with PostgreSQL, Redis, and AWS Lambda.
Each project ships with source code in your repo, automated CI/CD via GitHub Actions, and Sentry error tracking. Timeline is 8-12 weeks for a production API. Prices range from $80K-$250K depending on complexity. APIs are built to comply with HIPAA, PCI-DSS, or SOC 2 as needed.
We work with CTOs who need to replace legacy monolithic backends. We help startup founders launch their MVP with a scalable API. We partner with enterprise architects integrating microservices. We assist product managers who require a developer-friendly API for third-party integrations.

Why you need an expert backend API development vendor
Your backend API is the backbone of every digital product.
A poorly designed API leads to slow performance, security vulnerabilities, and integration headaches. IRPR applies industry best practices from day one.
We build APIs that handle 10K+ requests per second, scale horizontally on AWS, and comply with the strictest security standards. 200+ shipped products prove our process works.
Expert backend API development vendor vs generic dev shops
Not all development firms deliver production-grade APIs.
Generic dev shops often skip API design patterns, documentation, and monitoring. Their APIs break under load and lack security reviews.
IRPR treats your API as a product. We ship with OpenAPI specs, auto-generated docs, CI/CD, monitoring, and load testing. Your API is ready for the real world.
- No API design patterns
- No documentation
- No CI/CD
- No monitoring
- No security audit
- No scalability testing
- API-first design with OpenAPI specs
- Auto-generated Swagger docs
- GitHub Actions CI/CD pipeline
- Sentry & Datadog monitoring
- OWASP top 10 security review
- Load tested for 10K+ requests/sec
How we build your backend API
Our 4-phase process delivers a production-ready API in 8-12 weeks.
Phase 1 (Idea): We define API endpoints, data models, and integration points. Phase 2 (Roadmap): We scope the work and provide a fixed price.
Phase 3 (Product): We build the API with daily CI/CD, automated tests, and weekly demos. Phase 4 (Release): We deploy, monitor, and train your team.
What ships with your backend API
Every API project includes more than just code.
You get a complete production package: source code, documentation, infrastructure, and monitoring. No hidden extras.
- Source code in your repo
- OpenAPI 3.0 specification
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Postman collection
- Deployment playbook
- API documentation (Swagger UI)
- Security audit report
- Load testing results

Why teams hire us.
Fixed price, not hourly
Every backend API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
8-12 week delivery
Our process from Idea to Release takes 8-12 weeks for a production-grade API. 98% of our projects ship on schedule.
Full code ownership
You own all source code, documentation, and infrastructure config. We transfer everything to your GitHub and AWS accounts at handoff.
Security-first design
Every API undergoes an OWASP top 10 security audit and penetration testing. We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from day one.
Senior engineers only
Every IRPR engineer has 10+ years of experience building APIs at companies like Amazon and Google. No juniors, no offshoring.
Post-launch support
We provide 30 days of post-launch support with SLAs for critical fixes. You get ongoing maintenance and scaling guidance from the same team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
