Professional Backend API Development CompanyBackend API
We build production-grade backend APIs for web and mobile apps. 200+ APIs shipped in 50+ countries with 98% on-time delivery.
IRPR is a professional backend API development company. We build custom APIs using Node.js, Python (FastAPI), Go, Java Spring Boot, and .NET Core. Every API is designed with PostgreSQL or Redis for performance and AWS/GCP for cloud hosting.
A typical backend API project ships in 8-12 weeks with a fixed price between $60,000 and $200,000. We handle compliance requirements such as HIPAA, PCI-DSS, and SOC 2. Our team writes unit tests, API documentation, and sets up monitoring (Sentry, Datadog) before release.
We work with CTOs at early-stage SaaS companies who need to launch a product API fast. Enterprise architects hire us to re-platform legacy REST APIs. Product managers in fintech and healthtech rely on us for HIPAA-compliant backend services. Founders choose us for fixed pricing and full code ownership.
Types of software we ship.
REST API Backend
Standard RESTful APIs using Express.js or FastAPI with JWT auth, PostgreSQL, and OpenAPI documentation.
GraphQL API Server
GraphQL APIs using Apollo Server or Hasura with federated schemas, real-time subscriptions, and caching with Redis.
Microservices Backend
Microservice architecture with Docker, Kubernetes, message queues (RabbitMQ, Kafka), and gRPC for inter-service communication.
WebSocket Server
Real-time WebSocket servers using Socket.io or AWS IoT Core for live chat, notifications, and streaming data.
Serverless API (AWS Lambda)
Serverless APIs using AWS Lambda, API Gateway, and DynamoDB. Auto-scaled with pay-per-call pricing for unpredictable traffic.
API Gateway & Edge Services
API gateway layer using Kong or AWS API Gateway for rate limiting, caching, authentication, and routing to internal services.
Data API (ETL & Analytics)
Data aggregation APIs that pull from multiple sources (Stripe, Salesforce, databases) and expose unified endpoints for dashboards.
Real-time Bidding API
Low-latency APIs for ad-tech, auction systems, and financial trading with sub-10ms response times using Go and Redis.
We build for every business type.
Startups & SaaS
Fintech
Healthcare
E-commerce & Retail
Enterprise & Legacy
What we deliver as your professional backend API development company
Every backend API project includes more than just code. You get a production-ready service with monitoring, documentation, and deployment pipelines.
IRPR starts every backend API engagement with a 2-week Roadmap phase. We define the API contract (OpenAPI 3.0), choose the tech stack (Node.js, Python, Go, or Java), and set up CI/CD in GitHub Actions. You see a working prototype in week 3.
We build for scale from day one. APIs use connection pooling, caching with Redis, and auto-scaling on Kubernetes or AWS Fargate. Every endpoint is tested (unit, integration, load) and deployed with zero-downtime strategies.
Generic dev shops vs IRPR: your backend API project
Not every agency can build secure, scalable backend APIs on time and on budget. Here is how IRPR stands apart.
Many agencies staff junior developers, bill by the hour, and hand off code with no documentation. They often miss security compliance and monitoring. You end up with technical debt.
IRPR assigns senior engineers only. We quote a fixed price after the Roadmap phase. Every API ships with OpenAPI docs, test coverage, Sentry error tracking, and a Grafana dashboard. You own all code.
- Hourly billing with no cap
- Junior developers learn on your project
- No compliance experience
- API released without tests
- No monitoring or alerting
- Code ownership is unclear
- Fixed price after Roadmap phase
- All senior engineers (10+ years)
- HIPAA, PCI-DSS, SOC 2 ready
- 100% test coverage for critical endpoints
- Sentry + Datadog out of the box
- You own all source code and IP
How we build your backend API
Our process turns an idea into a live, monitored API in 8-12 weeks.
We start with a 2-week Roadmap phase where we write a detailed specification, choose the stack, and set up the infrastructure. You approve everything before we write a line of production code.
Development happens in 2-week sprints. We deploy to a staging environment after every sprint. You test the API and give feedback. The final sprint is for production hardening, monitoring, and documentation.
What ships with every backend API project
You get a complete, maintainable system, not just an endpoint.
Every project includes production-ready code deployed to your cloud account (AWS, GCP, or Azure). We set up CI/CD with GitHub Actions, test coverage with Jest or Pytest, and error tracking with Sentry.
You also receive OpenAPI 3.0 documentation, a Postman collection, and a Grafana dashboard for monitoring. All infrastructure is defined as code (Terraform or Pulumi).
- Source code in your private repository
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests (80%+ coverage)
- OpenAPI 3.0 documentation
- Postman or Insomnia collection
- Docker containers with Docker Compose
- Cloud infrastructure as code (Terraform)
- Sentry error tracking
- Datadog or Grafana monitoring dashboard
- Deployment runbook and operational guide
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a PCI-DSS compliant payment API using Node.js, Express, and Stripe Connect. Reduced failed transactions by 40% and cut integration time for merchants from 3 months to 2 weeks.
HIPAA-Compliant Patient Records API
Developed a FHIR-based API for a health-tech company. Handled 10,000 patient records per day with end-to-end encryption. Passed HIPAA audit on first attempt.
Real-Time Bidding API for Ad-Tech
Built a sub-10ms latency bid API in Go with Redis and WebSockets. Handled 50,000 QPS during peak events. Reduced cost per auction by 25%.
E-commerce Order Sync API
Created a REST API that syncs orders between Shopify, a custom warehouse system, and ShipStation. Eliminated manual data entry, saving 20 hours per week for the operations team.
SaaS Subscription Management API
Designed a metering and billing API using Python FastAPI and Stripe. Automatically tracks usage and generates invoices. Reduced billing errors by 90%.
Legacy SOAP-to-REST Migration for Logistics
Modernized a 15-year-old SOAP API to a RESTful microservice on AWS Lambda. Cut response time from 3 seconds to 200ms. Saved $12,000 per month in server costs.
Why teams hire us.
Fixed price, not hourly
Every backend API project gets a fixed quote after the 2-week Roadmap phase. No surprise invoices. If we miss a deadline, we add engineers at no extra cost.
Senior engineers only
Our team averages 12 years of experience. No junior developers. Every engineer has built production APIs for at least 5 years.
HIPAA, PCI, SOC 2 built-in
We design APIs to meet compliance from day one. Our healthcare APIs pass HIPAA audits. Fintech APIs meet PCI-DSS Level 1. SaaS APIs follow SOC 2 controls.
You own everything
All source code, API specifications, infrastructure scripts, and documentation are your property. No licensing fees. No ongoing royalties.
Delivery in 8-12 weeks
We ship a production-ready backend API in 8-12 weeks. Faster if you already have specifications. We have a 98% on-time track record across 200+ projects.
Async-first, no commute costs
Our team works across 12 time zones. You get daily updates and can schedule calls during your business hours. No travel costs or office rental wasted.
