Leading Backend API Development CompanyBackend API
We build high-performance backend APIs for SaaS, fintech, and healthcare. Ship in 12 weeks with fixed pricing.
IRPR builds production-grade backend APIs using Node.js, Python, Go, PostgreSQL, Redis, and Kafka. Every API is designed for scale, security, and low latency.
We ship custom backend API projects in 12 weeks on average, with fixed prices ranging from $80,000 to $250,000. All deliverables meet HIPAA, PCI-DSS, or SOC 2 compliance where required.
Our clients include CTOs scaling SaaS platforms, fintech founders needing PCI-compliant payment APIs, healthcare companies requiring HIPAA-compliant data exchange, and enterprise teams migrating from monoliths to microservices.
Types of software we ship.
REST API Development
Stateless REST APIs with JSON or XML. We use OpenAPI 3.1 specs and enforce rate limiting via Redis.
GraphQL API Development
Data-fetching APIs that let clients query exactly what they need. Built with Apollo Server and Nexus.
Microservices Architecture
Decoupled services communicating over gRPC or message queues. We deploy with Docker and Kubernetes.
API Integration Middleware
Broker APIs that connect multiple third-party services. Common integrations include Stripe, Salesforce, and Twilio.
Real-Time API (WebSocket)
Bi-directional APIs for live updates. Built with Socket.IO or Pusher, used in chat and collaboration tools.
API Gateway Implementation
Centralized entry point for routing, auth, and throttling. We use Kong or AWS API Gateway with custom plugins.
Third-Party API Wrapper
Abstraction layer over external APIs like Google Maps or Stripe. Includes caching and fallback logic.
Internal B2B API
APIs for partner integrations and internal tooling. We enforce OAuth 2.0 and provide detailed API documentation.
We build for every business type.
SaaS
Fintech
Healthcare
Ecommerce
IoT & Real-Time
Why IRPR Is a Leading Backend API Development Company
We ship high-quality APIs faster than most agencies while maintaining enterprise compliance.
IRPR has shipped 200+ products across 50 countries. Our backend APIs power SaaS platforms processing millions of requests per day, fintech systems handling PCI-DSS data, and healthcare platforms managing HIPAA-protected patient information.
We use a proven 4-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2) we lock the scope and price so you know exactly what you get and when.
How IRPR Differs from Generic API Development Shops
Most agencies bill by the hour and change scope mid-project. IRPR does the opposite.
Generic shops often use junior developers, change requirements, and underdeliver. IRPR assigns senior engineers only and fixes the price in week 2.
Our fixed-price model means you never pay for overtime or scope creep. We deliver a fully tested API with CI/CD, monitoring, and documentation included.
- Hourly billing with unpredictable costs
- Junior developers with little oversight
- Scope changes mid-project without budget adjustment
- No compliance expertise (HIPAA, PCI)
- Delayed timelines due to resource shuffling
- Code ownership may be unclear
- Fixed price agreed in week 2
- Senior engineers only (7+ years average experience)
- Scope locked after Roadmap phase
- HIPAA, PCI-DSS, SOC 2 built into every API
- 12-week average delivery, 98% on-time
- Full code ownership from day one
Our Backend API Development Process
We follow a 4-phase framework that reduces risk and speeds up delivery.
Every project starts with an Idea phase (1 week) where we understand your business goals and technical constraints. Then we move to Roadmap (1 week) where we define the API spec, data model, and fixed price.
The Product phase (8-10 weeks) is where we build, test, and deploy. Finally, Release (1 week) includes production launch, monitoring setup, and knowledge transfer.
What You Get with Every Backend API Project
Every deliverable is production-ready, documented, and fully owned by you.
We ship more than code. Each project includes infrastructure, monitoring, and a complete set of developer tools. You can deploy, scale, and maintain the API without depending on IRPR.
All our APIs are built with security in mind from the start. We include automated tests, rate limiting, and logging as standard features.
- Source code in your Git repository (GitHub/GitLab)
- CI/CD pipeline using GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- PagerDuty alerts for production incidents
- Load-balanced infrastructure on AWS or GCP
- Terraform or Pulumi infrastructure as code
- Postman collection for all endpoints
- Swagger/OpenAPI documentation hosted on your domain
- Rate limiting and API key authentication
- Unit and integration tests with 90%+ coverage
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a PCI-DSS Level 1 compliant payment API that reduced transaction failures by 40%. Used Node.js, PostgreSQL, and Stripe Connect with custom fraud detection rules.
Healthcare Data Exchange API
Developed a HIPAA-compliant FHIR API for a telemedicine platform. Enabled real-time patient record sharing across 50+ clinics, cutting data retrieval time by 70%. Stack: Python, Flask, PostgreSQL, Redis.
Real-Time Chat API for SaaS Collaboration Tool
Created a WebSocket-based API handling 10K concurrent connections with sub-200ms latency. Used Socket.IO, MongoDB, and AWS ECS. Reduced message delivery time by 60%.
Inventory API for Ecommerce Marketplace
Designed a RESTful inventory management API for a multi-vendor marketplace serving 500+ merchants. Integrated with warehouse systems via Apache Kafka. Stock accuracy improved to 99.8%.
IoT Device API for Manufacturing
Built a MQTT-based API for industrial sensors collecting 1 million readings per day. Used Go, InfluxDB, and AWS IoT Core. Identified machine failures 24 hours earlier than before.
Social Media API for Content Platform
Developed a GraphQL API for a media startup serving 2 million monthly users. Aggregated content from 10+ sources using a feed-building service. API response time dropped from 1.2s to 300ms.
Why teams hire us.
Fixed Price, Not Hourly
Every backend API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing means no surprise invoices and no scope creep charges.
Senior Engineers Only
Our engineers average 7+ years of experience in backend development. No juniors, no outsourcing to low-cost regions.
HIPAA and PCI Compliance Built-In
We implement encryption, access controls, audit logs, and data residency as standard. Over 30% of our projects require one of these certifications.
12-Week Delivery Guarantee
Most APIs ship in 8-12 weeks. We use a fixed scope and iterative sprints to maintain velocity. 98% of projects finish on time.
Full Code Ownership
You own every line of code, every configuration file, and all documentation. No licensing fees or recurring royalties.
Dedicated Project Manager
A single point of contact coordinates engineers, provides weekly updates, and handles escalations. No need to manage a distributed team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
