Top Backend API Development StudioBackend API
We build scalable, secure REST and GraphQL APIs. Ship production-ready backend systems in 8 to 12 weeks with fixed pricing.
IRPR is a top backend API development studio that delivers production-grade APIs using Node.js, Express, Apollo Server, and AWS Lambda. We focus on building RESTful and GraphQL APIs that handle millions of requests with sub-50ms response times.
Our fixed-price model starts at $80K and goes up to $250K for a complete backend API system, delivered in 8 to 12 weeks. All APIs are built to SOC 2, PCI-DSS, and HIPAA compliance standards depending on the industry.
We work with SaaS founders who need a scalable API from day zero, fintech companies requiring PCI-compliant payment APIs, and enterprise teams migrating from monoliths to microservices. Every engagement starts with a senior engineer, never a junior.
Types of software we ship.
REST API Development
Stateless HTTP APIs using Node.js and Express. Built with JWT authentication, rate limiting, and OpenAPI 3.0 docs.
GraphQL API Development
Schema-first GraphQL APIs using Apollo Server. Resolvers are type-safe and support real-time subscriptions via WebSockets.
Microservices Architecture
Decoupled services with message queues (RabbitMQ, SQS) and Docker/Kubernetes orchestration. Each service has its own database.
API Integration
Third-party integrations with Stripe, Salesforce, HubSpot, and 50+ other APIs. Webhook handling and data sync included.
Real-Time API (WebSockets)
WebSocket-based APIs for chat, live dashboards, and collaborative tools. Built on Socket.IO or AWS API Gateway WebSockets.
API Gateway Development
Single entry point for all services with Kong or AWS API Gateway. Handles authentication, throttling, and request transformation.
Backend-as-a-Service (BaaS) Custom
Custom BaaS platforms that provide authentication, storage, and serverless functions via a unified API. Built on Firebase or Supabase.
Data API for Analytics
High-throughput APIs that serve aggregated data from BigQuery, Redshift, or PostgreSQL. Optimized for OLAP queries and sub-second response.
We build for every business type.

healthcare
fintech
SaaS

Why choose a top backend API development studio
Building a production-grade backend API requires more than just writing routes — it demands architecture, security, and scale.
IRPR's backend API studio has shipped 200+ production APIs for clients in 50+ countries. Our APIs handle everything from 100 requests per minute to 10,000 requests per second without degradation.
Every API we build includes automated load testing (using k6), circuit breakers, and structured logging with ELK stack. We deliver on time — 98% of our projects hit the agreed milestone dates.
How IRPR differs from a generic dev shop
Most agencies sell hours. IRPR sells outcomes — a fixed-price, senior-only backend API that ships on time.
Generic dev shops assign a mix of juniors and seniors, bill hourly, and change scope mid-project. Their APIs often lack documentation, monitoring, or a proper CI/CD pipeline.
IRPR assigns only senior engineers with 8+ years of experience. We use a fixed-price Roadmap phase (week 2) to lock scope. Every API ships with full test coverage, auto-generated docs, and a staging environment.
- Weekly hourly billing with unclear totals
- Mixed senior and junior engineers
- Scope creep is common and expensive
- No dedicated QA or load testing
- API docs are an afterthought
- CI/CD pipeline often missing
- Fixed price locked in Roadmap phase (week 2)
- Only senior engineers with 8+ years experience
- Scope is fixed; changes are priced upfront
- Automated load testing with k6 and unit tests with Jest
- OpenAPI 3.0 docs generated automatically
- Full CI/CD on GitHub Actions with Docker deployment
Our backend API development process
We follow a 4-phase process that moves from idea to production in 8 to 12 weeks.
Every project starts with a Discovery call to understand your data model, expected traffic, and compliance needs. We then build a detailed Roadmap with wireframes, endpoints, and a fixed price.
During the Build phase, we work in 2-week sprints with daily standups and a living demo environment. The Release phase includes load testing, security audit, and deployment to your production cloud account.
What ships with every backend API
Every project includes a complete delivery package — not just code.
You get more than a working API. We deliver observability, security, and documentation so your team can take over immediately.
All artifacts are placed in your own GitHub repository. We never hold your code hostage. Infrastructure is defined as code using Terraform or Pulumi.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (Swagger UI)
- CI/CD pipeline on GitHub Actions
- Dockerized services with docker-compose
- Automated tests (unit + integration, Jest)
- Load test script (k6) for benchmarking
- Sentry error tracking and Datadog metrics
- Postman collection for all endpoints
- Terraform scripts for infrastructure as code
- Deployed to your cloud (AWS, GCP, or Azure)
What we ship in this practice.
Real-time inventory sync API for a multi-warehouse ecommerce brand
Built a WebSocket-based API to sync inventory across 3 warehouses in real time. Reduced stockouts by 60% and order cancellations by 40%. Stack: Node.js, Socket.IO, Redis, PostgreSQL.
HIPAA-compliant telehealth video API for a healthcare startup
Developed a WebRTC-based API with end-to-end encryption and automatic transcription. Passed HIPAA audit in week 10. Stack: Twilio Video, AWS KMS, MongoDB, Express.
PCI-compliant payment processing API for a fintech B2B platform
Created a tokenized payment API that integrates with Stripe and Plaid. Processed $12M in transactions in the first quarter. Stack: Node.js, Stripe Connect, Plaid, AWS ECS, RDS.
Microservice migration API for a legacy SaaS platform
Decomposed a monolith into 15 microservices with an API gateway. Reduced deployment time from 3 hours to 12 minutes. Stack: Kong, GraphQL Federation, Docker, Kubernetes on EKS.
Carrier rate and tracking API for a logistics aggregator
Built a unified API that normalizes rate data from 8 carriers and tracks shipments in real time. Onboarded 200+ shippers in 3 months. Stack: Node.js, Redis, RabbitMQ, PostgreSQL.
Real-time chat API for an EdTech tutoring platform
Developed a WebSocket-based chat API with file sharing, moderation, and session persistence. Supported 5,000 concurrent users from day one. Stack: Socket.IO, AWS S3, MongoDB, Elasticsearch.
Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has 8+ years of experience in backend development. No junior or mid-level engineers are assigned to billable work. You get a lead engineer who owns delivery end to end.
Fixed price, not hourly billing
After the Roadmap phase (week 2), the total price is locked. No hourly rates, no surprise invoices. If the scope grows, we re-quote transparently with your approval.
Full code ownership from day one
All code is written in your GitHub organization. You own the repos, the CI/CD pipelines, and the cloud infrastructure. We are contractors, not code hostage takers.
98% on-time delivery record
We track milestones against the Roadmap every week. If a risk appears, we communicate it before week's end. Our track record: 98% of projects finish within the agreed timeline.
Compliance built in (SOC 2, PCI, HIPAA)
We architect APIs with compliance from the start. For fintech, we include tokenization and encryption. For healthcare, we implement audit logging and RBAC. For SaaS, we support SOC 2 controls.
Post-launch support included for 30 days
After launch, we provide 30 days of bug fixes and minor tweaks at no extra cost. We also hand over documentation and train your internal team on maintaining the API.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
