Experienced Backend API Development PartnerBackend API
We build production-grade APIs that handle millions of requests. 200+ products shipped, 8-12 week MVPs, fixed pricing.
IRPR is an experienced backend API development partner for companies that need reliable, scalable APIs. We use Node.js, Python, Go, and Rust to build REST, GraphQL, and gRPC APIs that integrate with Stripe, Salesforce, Twilio, and more.
Every project ships in 8-12 weeks with a fixed price from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get source code, CI/CD pipelines, and monitoring in your own AWS or GCP account.
CTOs hire us when their in-house team is at capacity. Startup founders hire us to build their first production API. Product managers hire us to replace a legacy SOAP or REST API with a modern microservices architecture.

Why you need an experienced backend API development partner
A poorly designed API costs you time, money, and customer trust.
IRPR has shipped 200+ backend APIs for companies in fintech, healthcare, ecommerce, and logistics. We use Node.js, Python, Go, and Rust to build APIs that handle 10,000 requests per second with 99.9% uptime. Every API includes OpenAPI documentation, automated tests, and monitoring with Datadog or New Relic.
Our fixed-price model means you know the cost before we write a line of code. In the Roadmap phase (week 2), we deliver a detailed specification with endpoints, data models, and integration points. No surprises, no scope creep.
Generic dev shop vs experienced backend API development partner
Not all development teams can build production-grade APIs.
Generic dev shops often deliver APIs that are slow, insecure, and undocumented. They skip load testing, ignore rate limiting, and leave you with a codebase that no one can maintain. IRPR is different.
We treat your API as a product. Every endpoint is documented, tested, and monitored. We use infrastructure-as-code with Terraform and CI/CD with GitHub Actions. Your API ships with a runbook, a monitoring dashboard, and a postman collection.

- 30-day post-launch support included
How we build your backend API in 8-12 weeks
Our process is designed for speed and quality.
We start with a 2-week Roadmap phase where we define every endpoint, data model, and integration point. You get a fixed price and a detailed specification. No ambiguity, no surprises.
Then we build in 2-week sprints. You see working code every 14 days. We deploy to staging on AWS or GCP, run automated tests, and demo the API to your team. By week 8-12, your API is production-ready.
What ships with every backend API
You own everything. No black boxes, no vendor lock-in.
When IRPR builds your API, you get the full source code in your own GitHub or GitLab repository. We set up CI/CD pipelines, monitoring, and error tracking. You can deploy, modify, and scale the API without us.
We also ship documentation, a Postman collection, and a runbook. Your team can onboard in hours, not weeks. Every API includes a 30-day post-launch support period where we fix bugs and answer questions.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- OpenAPI 3.0 documentation
- Postman collection with example requests
- Docker Compose for local development
- Terraform scripts for AWS or GCP infrastructure
- Datadog or New Relic monitoring dashboard
- Sentry error tracking
- Runbook with deployment and rollback steps
- 30-day post-launch support
What we ship in this practice.
Payment processing API for a fintech startup

Property listing API for a real estate platform
Built a GraphQL API that aggregates listings from 3 MLS providers. Reduced listing sync time from 4 hours to 15 minutes. Tech stack: Node.js, Apollo Server, MLS APIs, AWS Lambda.
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 code.
8-12 week delivery
We ship production-grade APIs in 8-12 weeks. Our average is 10 weeks. We use 2-week sprints with working demos every 14 days.
Senior engineers only
Every engineer on your project has 8+ years of experience. No juniors, no offshore teams. Your API is built by someone who has shipped 20+ production APIs.
Full code ownership
You own the source code, the CI/CD pipeline, and the infrastructure. No vendor lock-in. You can deploy, modify, and scale without us.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant APIs. We use encryption at rest and in transit, audit logging, and access controls by default.
Post-launch support included
Every project includes 30 days of post-launch support. We fix bugs, answer questions, and help your team onboard. No additional cost.
Idea → Roadmap → Product → Release.
