Affordable Backend API Development FirmBackend API
We build production-grade backend APIs for startups and mid-market companies. Fixed pricing. 8-12 week delivery. Senior engineers only.
IRPR is an affordable backend API development firm that builds production-grade APIs for startups and mid-market companies. We use Node.js, Python, Go, and Postgres to create REST, GraphQL, and gRPC APIs that handle millions of requests per day.
Every project ships with a fixed price, source code ownership, and a CI/CD pipeline. Timeline is 8-12 weeks for an MVP. Price range is $80K to $250K depending on complexity. We comply with HIPAA, PCI-DSS, and SOC 2 standards as needed.
Founders hire us when they need a backend API built fast without hiring a full team. CTOs hire us to extend their existing engineering capacity. Product managers hire us to build internal tools and third-party integrations. All buyers get a senior engineer as their primary point of contact.
Types of software we ship.
REST API Development
Build stateless REST APIs with Express or Fastify. Supports versioning, rate limiting, and OpenAPI docs.
GraphQL API Development
Build type-safe GraphQL APIs with Apollo or Yoga. Includes schema stitching, caching, and real-time subscriptions.
Microservices API
Decompose monoliths into independent services. Use Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
Third-Party API Integration

Why Choose an Affordable Backend API Development Firm
IRPR has shipped 200+ backend APIs for companies in 50+ countries.
We are an affordable backend API development firm that focuses on speed and quality. Every project starts with a 2-week Roadmap phase where we define the data model, endpoints, and deployment plan. You get a fixed quote before any code is written.
Our engineers have built APIs that handle 10,000+ requests per second. We use Node.js, Python, Go, and Rust depending on your performance needs. Every API ships with automated tests, monitoring, and documentation.
How IRPR Differs from Generic Development Shops
Most agencies charge by the hour and deliver late. IRPR does the opposite.
Generic dev shops often start building without a clear plan. They bill hourly, change scope mid-project, and hand over code with no documentation. You end up paying more for less.
IRPR fixes this with a fixed-price model, a detailed Roadmap, and senior engineers who write tests and documentation as part of the build. You own the code from day one.
- Hourly billing with no cap
- No written roadmap before build
- Junior or offshore developers
- No automated tests
- No CI/CD pipeline
- No documentation
- Fixed price agreed in week 2
- Detailed Roadmap with endpoints and schema
- Senior engineers with 8+ years experience
- Automated test suite with 90%+ coverage
- CI/CD pipeline on GitHub Actions
- OpenAPI or GraphQL schema docs
Our API Development Process: Roadmap to Release
Every project follows a proven 4-phase process that eliminates surprises.
Phase 1: Roadmap. In 2 weeks we define the data model, API endpoints, authentication strategy, and deployment plan. You get a fixed price and timeline.
Phase 2: Build. We build the API in 6-10 weeks using Node.js, Python, or Go. Every endpoint gets unit tests and integration tests. We deploy to a staging environment for your review.
What Ships with Every API Project
You get a production-ready API, not just code.
Every project includes everything needed to run and maintain the API in production. No hidden deliverables. No extra charges for deployment or documentation.
Source code is delivered to your GitHub or GitLab repo. All infrastructure is defined in Terraform or Pulumi, so you can reproduce it anywhere.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions
- Automated test suite (unit + integration)
- API documentation (OpenAPI or GraphQL schema)
- Docker containers for local development
- Sentry error tracking and logs
- Monitoring dashboard (Datadog or Grafana)
- Infrastructure as code (Terraform)

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 single line of code.
Senior engineers only
Every project is staffed with engineers who have 8+ years of experience building production APIs. No junior developers. No offshore teams. Your lead engineer is the same person from Roadmap to Release.
8-12 week MVPs
We ship a production-ready API in 8-12 weeks. That includes the data model, all endpoints, automated tests, monitoring, and deployment. We have shipped 200+ products on time 98% of the time.
Full code ownership
You own all source code, documentation, and infrastructure files from day one. No licenses, no royalties, no lock-in. You can take the code and run it anywhere.
Compliance built in
We build APIs that comply with HIPAA, PCI-DSS, SOC 2, and GDPR. We use encryption at rest and in transit, audit logging, and role-based access control. Compliance is not an afterthought.
No long-term contract
We work on a project-by-project basis. After the initial build, you can choose to continue with us for maintenance and features, or take the code and hire your own team. No minimum commitment.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
