Premium Backend API Development ConsultantsAPI Development
We build production-grade APIs for startups and enterprises. Fixed price, 12-week delivery, full documentation included.
IRPR builds premium backend APIs that handle millions of requests per day. We use Node.js, Python, Go, and Rust with PostgreSQL, Redis, and Kafka for high-throughput systems. Every API is designed for horizontal scaling and includes auto-generated OpenAPI documentation.
A typical API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance out of the box: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS. You get source code, CI/CD pipelines, and load testing reports.
CTOs scaling infrastructure hire us to replace legacy monoliths. Founders building API-first products hire us for speed without technical debt. Enterprise teams migrating to microservices hire us to design and implement their gateway strategy.
Types of software we ship.
REST API Development
Standard CRUD APIs with versioning, rate limiting, and pagination. Built on Express.js or FastAPI with PostgreSQL.
GraphQL API Design
Single endpoint with flexible queries. Apollo Server or Hasura with subscription support for real-time data.
Microservices Architecture
Decoupled services communicating via message queues. Docker, Kubernetes, and gRPC for inter-service calls.
API Gateway Implementation
Centralized gateway for routing, auth, and throttling. Kong, AWS API Gateway, or custom NGINX configs.
Real-Time API (WebSocket)
Persistent connections for live updates. Socket.IO, WebSocket, or Server-Sent Events with Redis pub/sub.
API Security Consulting
OAuth 2.0, JWT, API keys, and rate limiting. Penetration testing and OWASP compliance audits.
API Documentation & SDKs
Auto-generated OpenAPI/Swagger docs plus client SDKs in Python, JavaScript, and Java.
API Integration Middleware
Connecting third-party APIs (Stripe, Salesforce, Twilio) with custom transformation and error handling.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Logistics
Why premium backend API development consultants matter
A poorly designed API costs you weeks of rework and lost customers. We build APIs that scale from day one.
IRPR has shipped over 200 APIs for clients in 50 countries. Our average API handles 10 million requests per month with 99.9% uptime. We use load testing tools like k6 and Artillery to validate performance before launch.
Every API includes auto-generated OpenAPI documentation, a Postman collection, and a CI/CD pipeline with GitHub Actions. You get a complete artifact, not just code.
The difference between IRPR and generic dev shops
Most agencies sell hours. We sell outcomes with fixed pricing and senior engineers.
Generic shops assign junior developers who learn on your dime. They bill hourly and change scope without warning. Documentation is an afterthought, and compliance is your problem.
IRPR assigns a senior engineer (10+ years experience) as lead. We give you a fixed price in week 2. Compliance is baked into every build. Documentation ships with the code.
- Hourly billing with no cap
- Junior developers with 2-3 years experience
- No dedicated project manager
- Compliance handled as an afterthought
- No API documentation delivered
- No CI/CD pipeline included
- Fixed price from the Roadmap phase
- Senior engineers with 10+ years experience
- Dedicated PM with weekly updates
- HIPAA, SOC 2, PCI compliance built in
- Auto-generated OpenAPI docs shipped
- CI/CD pipeline on GitHub Actions included
How we build your premium backend API
We follow a four-phase process that turns your idea into a production-grade API.
Phase 1: Discovery & Roadmap (2 weeks). We interview stakeholders, map data flows, and produce a fixed-price proposal. You get a detailed roadmap with wireframes and API contracts.
Phase 2: Design & Architecture (2 weeks). We choose the right stack (Node.js, Go, or Python), design the database schema, and set up the CI/CD pipeline. You review and approve before any code is written.
What ships with every API project
You get a complete, production-ready artifact. Not just code.
Every project includes source code in your repository, a CI/CD pipeline, and infrastructure-as-code templates. We also provide a load testing report and a security audit checklist.
Documentation is auto-generated from your code using Swagger/OpenAPI. You get a Postman collection for manual testing and a deployment runbook for your operations team.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions with automated tests
- Docker containers for local development and production
- API documentation via Swagger/OpenAPI (auto-generated)
- Postman collection with example requests
- Sentry error tracking and uptime monitoring
- AWS CloudFormation or Terraform templates
- Load testing report using k6 (10k concurrent users minimum)
- Security audit checklist (OWASP Top 10)
- Deployment runbook for your DevOps team
What we ship in this practice.
PCI-compliant payment API for fintech startup
Built a tokenization API that reduced fraud by 40% and passed PCI-DSS Level 1 audit on first try. Tech stack: Node.js, Stripe, AWS Lambda, DynamoDB.
HIPAA-compliant FHIR API for telehealth platform
Designed a GraphQL FHIR API that cut data sync latency by 60%. Handles 500k patient records with sub-200ms response times. Tech stack: Apollo Server, PostgreSQL, Redis.
Order management API for 500k SKU ecommerce brand
Replaced a legacy SOAP API with a RESTful system that reduced response time from 800ms to 50ms using Redis caching. Tech stack: FastAPI, PostgreSQL, Redis, Docker.
Multi-tenant API for SaaS CRM platform
Built a multi-tenant API that enabled the client to scale from 100 to 10,000 users without downtime. Tech stack: Go, PostgreSQL, Kubernetes, gRPC.
Real-time tracking API for logistics fleet
Implemented a WebSocket-based API that improved ETA accuracy by 35% and reduced support calls by 20%. Tech stack: Node.js, Socket.IO, Kafka, InfluxDB.
Content delivery API for media streaming platform
Designed a CDN-backed API serving 10 million daily requests with 99.99% uptime. Tech stack: Python, FastAPI, CloudFront, ElastiCache.
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. Our average API project costs $80K-$250K.
Senior engineers only
Every lead engineer has 10+ years of backend experience. We never outsource or use junior developers. You work directly with the person building your API.
Compliance built in, not bolted on
We handle HIPAA, SOC 2, and PCI-DSS compliance as part of the architecture. No separate audit cycles. Our APIs pass compliance audits on the first try 98% of the time.
Async-first, overlap with US time zones
Our team operates with 4+ hours of overlap with US time zones. You get daily async updates via Slack and a weekly video call with the lead engineer.
Documentation included
Every API ships with auto-generated OpenAPI docs, a Postman collection, and a deployment runbook. Your team can start integrating within hours of launch.
30-day post-launch support
After deployment, we provide 30 days of free support for bug fixes and minor changes. Optional retainer available for ongoing maintenance.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
