Professional Backend API Development PartnerAPI Development
We build production-grade backend APIs that scale. Fixed price, delivered in 8-12 weeks with full ownership.
IRPR builds professional backend APIs for products that handle real traffic. We use Node.js, Go, Python, PostgreSQL, Redis, and Kubernetes to create APIs that serve thousands of requests per second.
Every project ships with a CI/CD pipeline, automated tests, API documentation (OpenAPI), and monitoring (Sentry, Datadog). Timeline is 8-12 weeks, price ranges from $80K to $250K depending on complexity. We support SOC 2, HIPAA, and PCI-DSS compliance.
We work with startup CTOs building their first product, product managers launching a new feature, enterprise architects migrating to microservices, and scale-up founders needing a reliable backend partner.
Types of software we ship.
REST API Development
HTTP-based APIs following REST principles. Built with Express.js, FastAPI, or Django REST Framework. Includes versioning, pagination, and rate limiting.
GraphQL API Development
Flexible APIs using Apollo Server or Yoga. Ideal for complex data queries and real-time subscriptions. Supports schema stitching and federation.
WebSocket API Development
Real-time bidirectional communication using Socket.io or WebSocket protocol. Used for chat, live notifications, and gaming backends.
gRPC API Development
High-performance RPC framework using Protocol Buffers. Best for internal microservices communication. Supports streaming and bi-directional calls.
Backend for Frontend (BFF)
Dedicated API layer for each frontend client. Optimized for mobile, web, or TV apps. Reduces payload size and simplifies client logic.
API Gateway
Centralized entry point using Kong, AWS API Gateway, or Envoy. Handles authentication, rate limiting, routing, and caching at scale.
Internal API / Service API
APIs for internal services and third-party integrations. Built with secure authentication (OAuth2, JWT) and detailed audit logs.
Partner API / External API
Public-facing APIs for partners and developers. Includes developer portals, API keys, usage analytics, and SDK generation (OpenAPI).
We build for every business type.
SaaS platforms
Ecommerce
Fintech
Healthcare
Logistics
Backend API development with proven metrics
Every API we build is measured against real performance and reliability standards.
IRPR has shipped 200+ products with backend APIs serving over 10 million requests per day. We track uptime, latency, and error rates on every project. Clients see 99.9% uptime and response times under 100ms at the 95th percentile.
Our 8-12 week delivery cadence means you get a production-ready API in a quarter or less. No scope creep. No surprise invoices. Fixed price from the Roadmap phase.
Why choose IRPR as your backend API partner
Most dev shops deliver code. We deliver a production system that actually runs.
A generic dev shop might hand you a GitHub repo and disappear. IRPR ships your API with monitoring, alerts, scaling rules, and a runbook. We stay until you are confident running it yourself.
Our fixed-price model means you know the cost upfront. We start with a 1-2 week Roadmap where we define every endpoint, data model, and integration. No hidden costs.
- Vague estimates and hourly billing
- No monitoring or alerting out of the box
- Only code, no documentation beyond comments
- No load testing or performance benchmarking
- You manage deployment and scaling yourself
- No post-delivery support commitment
- Fixed price from the Roadmap phase (week 2)
- Sentry error tracking and Datadog dashboards included
- OpenAPI docs, Postman collection, integration tests shipped
- Load tested with k6 to handle 10x projected traffic
- CI/CD pipeline on GitHub Actions with auto-scaling config
- 2 weeks of post-release support and knowledge transfer
Our API development process from idea to live
We use the same 4-phase framework for every backend API project.
Phase 1 (Idea) defines the core endpoints and integrations. Phase 2 (Roadmap) breaks everything into a fixed-price contract with a timeline. Phase 3 (Product) is the build. Phase 4 (Release) includes deployment and monitoring setup.
No phase takes longer than 3 weeks except the build phase, which is 4-8 weeks depending on API complexity. Each phase ends with a demo and sign-off.
What ships with your backend API
You get a complete production system, not just code.
When IRPR delivers your API, you get everything needed to run it in production: CI/CD pipeline, monitoring, automated tests, and deployment scripts. No subprocessors needed.
All source code is in your GitHub/GitLab repo from day one. You own it fully. No licensing fees, no royalties.
- Source code in your repo with commit history
- CI/CD pipeline on GitHub Actions or GitLab CI
- API documentation (OpenAPI / Swagger)
- Postman collection with example requests
- Integration tests with 80%+ coverage
- Load testing report from k6
- Sentry error tracking configured
- Datadog dashboard for latency and throughput
- Docker Compose or Kubernetes manifests
- Release runbook with rollback procedure
What we ship in this practice.
SaaS platform REST API
We built a multi-tenant REST API for a B2B SaaS company using FastAPI, PostgreSQL, and Redis. The API handles 5,000 requests per second and reduced their time-to-integrate for new partners from 6 weeks to 1 week.
Ecommerce product catalog API
Developed a GraphQL API for an online retailer using Apollo Server and Elasticsearch. Product search latency dropped from 800ms to 50ms. API serves 10,000+ products to mobile and web clients.
Fintech payment processing API
Created a PCI-DSS compliant API for a payment processor using Go, Stripe integration, and encrypted database. The API processes 2,000 transactions per minute with 99.99% uptime over 12 months.
Healthcare patient data API
Built a HIPAA-compliant FHIR API for a telemedicine platform using Node.js, MongoDB, and AWS HealthLake. The API enables real-time patient data exchange between 3 hospitals and reduced manual data entry by 12 hours per day.
Logistics real-time tracking API
Developed a WebSocket API for a fleet management startup using Socket.io and Redis. The API streams GPS coordinates from 500+ vehicles with sub-second latency, enabling live map updates for dispatchers.
Media content delivery API
Built a CDN-backed API for a video streaming platform using Python, CloudFront, and DynamoDB. The API serves 50TB of video content monthly with 99.9% availability and zero downtime during traffic spikes.
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 exact cost before we write a single line of production code.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects finish on schedule.
Full code ownership
All source code, documentation, and infrastructure config belongs to you from day one. IRPR retains no IP. You can take the code anywhere.
Production monitoring included
Every API ships with Sentry error tracking, Datadog dashboards, and uptime alerts. We don't hand over a black box. You see exactly how your API performs.
Compliance-ready architecture
We build APIs that meet SOC 2, HIPAA, and PCI-DSS requirements. Our team has delivered compliant systems for fintech and healthcare clients in 50+ countries.
Senior engineers only
Every IRPR engineer has 8+ years of experience building backend systems. No junior developers. You get a senior engineer leading your project end to end.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
