Professional Backend API Development AgencyBackend API
Build APIs that handle millions of requests. We deliver production-ready backend systems in 8-12 weeks.
IRPR builds REST and GraphQL APIs using Node.js, Python, and Go. Our systems integrate with AWS Lambda, Docker, and PostgreSQL to handle high traffic and complex data. Every API is designed for scalability from day one.
Projects ship in 8-12 weeks with fixed pricing from $80K to $250K. We follow HIPAA, PCI-DSS, and SOC 2 compliance where needed. Our senior engineers write every line of code.
We work with CTOs scaling their product, startup founders needing a secure backend, enterprise teams modernizing legacy systems, and product managers launching SaaS platforms. They all hire us for one reason: predictable delivery without surprise costs.
Types of software we ship.
REST API Development
RESTful endpoints for CRUD operations, built with Express or FastAPI. Includes pagination, caching, and rate limiting.
GraphQL API Development
Flexible queries with Apollo Server or Yoga. Reduces over-fetching and speeds up frontend development.
Microservices Architecture
Decoupled services communicating via gRPC or message queues like RabbitMQ. Each service scales independently.
API Gateway Setup
Centralized gateway using Kong or AWS API Gateway. Handles auth, logging, and throttling for multiple services.
Real-time WebSocket API
Bidirectional communication for chat, live updates, and IoT. Built with Socket.io or native WebSockets on Node.js.
Serverless Backend
Lambda functions with API Gateway or Cloud Run. Pay-per-use scaling and zero server management.
Third-party API Integration
Connect Stripe, Salesforce, Shopify, or custom endpoints. Error handling and retry logic included.
Internal API for Dev Teams
Internal REST or gRPC APIs with Swagger docs and SDK generation. Designed for team productivity.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Logistics
What Ships When You Hire a Professional Backend API Development Agency
Every API project from IRPR comes with a complete set of deliverables that most agencies skip.
You get a production-ready API designed for your exact use case. We follow an architecture-first approach: before writing code, we define endpoints, data models, and error handling strategies. This cuts rework by 40%.
Our delivery includes automated tests, CI/CD pipelines, and infrastructure-as-code templates. You can deploy to AWS, GCP, or Azure within hours. We also provide Postman collections and OpenAPI documentation so your frontend team can start integration day one.
Generic Agency vs Professional Backend API Development Agency
Not all agencies deliver the same quality. Here is what separates IRPR from the rest.
Most generic dev shops treat API development as an add-on. They reuse boilerplate code, skip testing, and bill you for every hour. The result is a fragile backend that breaks under load.
IRPR treats your API as the core product. We design for scale, security, and maintainability. Every project includes a fixed-price contract, full code ownership, and a 12-month warranty.
- Hourly billing with no cap
- No clear timeline
- Code you don't own
- No testing or CI/CD
- One-size-fits-all architecture
- Slow communication
- Fixed-price contract from week 2
- 8-12 week delivery guarantee
- Full code ownership in your repo
- Automated testing and CI/CD out of the box
- Architecture designed for your specific API needs
- Slack-based communication with daily standups
Our Process for Professional Backend API Development
We follow a 4-phase approach that de-risks your project and delivers on schedule.
Phase 1 is the Idea phase where we align on goals and constraints. Phase 2 is Roadmap where we define endpoints, data models, and a fixed price. This takes 1-2 weeks.
Phase 3 is Product where we build the API in sprints. Phase 4 is Release where we deploy, monitor, and hand over full ownership. Throughout, you see progress in a shared project board.
What Ships by Default in Every API Project
These are the concrete deliverables you receive at the end of every engagement.
No hidden add-ons. Every item on this checklist is included in the fixed price. You can start using the API immediately after deployment.
- Source code in your private GitHub repo
- Postman/Insomnia API collection with sample requests
- Swagger/OpenAPI 3.0 documentation
- CI/CD pipeline with GitHub Actions
- Dockerized services with docker-compose files
- AWS or GCP deployment scripts (Terraform/CloudFormation)
- Sentry error tracking and uptime monitoring
- Unit and integration tests (coverage >80%)
- API monitoring dashboard (Grafana + Prometheus)
- Security audit report with recommendations
What we ship in this practice.

Why teams hire us.
Fixed Price from Week 2
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 total cost before we write code.
Senior Engineers Only (US & EU)
Our team consists of senior engineers with an average of 10+ years experience. No juniors, no outsourcing. Every API is architected by someone who has built production systems for 50+ clients.
Full Code Ownership
You own every line of code we write. We deliver source code in your private repository with a license that gives you unrestricted rights. No proprietary frameworks, no lock-in.
8-12 Week Delivery Guarantee
We commit to a timeline and stick to it. Our average delivery is 10 weeks, and 98% of projects ship on time. If we miss, we work extra days at no cost.
Compliance Built In (HIPAA, PCI, SOC 2)
We build APIs that pass compliance audits. Our healthcare APIs meet HIPAA, fintech APIs meet PCI-DSS, and SaaS APIs follow SOC 2 controls. We handle encryption, logging, and access controls.
Long-Term Support After Launch
Every project includes 12 months of bug fixes and priority support. We monitor your API with Sentry and respond to incidents within 4 hours. You can extend support at a fixed monthly rate.
