Senior API Development CompanyAPI Development
Your senior API development company ships scalable, production-ready APIs in 8-12 weeks. Stop guessing on timelines. Get a fixed price and full code ownership.
IRPR is a senior API development company that builds secure, scalable APIs for web and mobile applications. We use Node.js, Python, and Go with REST or GraphQL, and deploy on AWS or Azure with CI/CD pipelines configured from day one.
We ship production-ready APIs in 8-12 weeks with fixed pricing from $80K to $250K. Every API is built to comply with HIPAA, PCI-DSS, and SOC 2 standards where required. You own the full code and IP.
We work with CTOs who need to scale integrations without hiring, product owners launching SaaS APIs, fintech startups requiring PCI-DSS compliant payment APIs, and healthcare companies building HIPAA compliant patient data APIs.
Types of software we ship.
RESTful Web API
Stateless, cacheable APIs for CRUD operations. Built with Express, FastAPI or Gin. Ideal for mobile and web backends.
GraphQL API
Flexible, typed queries that fetch exactly what you need. We use Apollo Server or Hasura. Reduces over-fetching by 40%.
Real-time WebSocket API
Persistent connections for live updates. Built with Socket.io, Redis Pub/Sub, or WebSocket. Used for chat, dashboards, logistics tracking.
Payment API
PCI-DSS Level 1 compliant payment processing. Integrates Stripe, Braintree, or Adyen. Handles subscriptions, invoicing, fraud checks.
Third-party Integration API
Custom connectors to Salesforce, HubSpot, QuickBooks, or any REST/SOAP service. Includes error handling and rate limiting.
Internal Microservice API
Lightweight, domain-specific services using gRPC or RabbitMQ. Designed for independent deployment and scaling within your architecture.
Mobile Backend API
Optimized for iOS and Android with Push Notifications (Firebase/APNs), offline sync, and efficient payloads. Uses Firebase or custom Node.js.
Data Sync API
Batch and incremental data synchronization across systems. Uses Kafka, Debezium, or AWS DMS. Guarantees eventual consistency with conflict resolution.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Real Estate
Why hire a senior API development company like IRPR?
Most API projects fail because of loose scopes, junior talent, and no compliance awareness. IRPR delivers on time, on budget, and to spec.
We have shipped over 200 APIs for clients in 50 countries. Our average project delivers a production-ready API in 12 weeks. We maintain 99.9% uptime across all deployed services.
Every API we build includes automated testing (90%+ coverage), OpenAPI 3.0 documentation, and a CI/CD pipeline on GitHub Actions. We audit for OWASP Top 10 vulnerabilities before handoff.
How IRPR differs from generic dev shops
Hiring a senior API development company is not the same as hiring a freelancer or a body shop. Here is the real difference.
Generic dev shops bill by the hour and change scope without warning. They often assign junior developers to your project. They skip compliance and you end up owning code you cannot deploy.
IRPR works differently. We assign senior engineers only, give you a fixed price in week 2, and ship compliant, documented APIs. You own the code from day one.
- Hourly billing with no cap
- No compliance experience (HIPAA, PCI)
- Junior developers on your account
- Hidden costs for infrastructure setup
- No documented process for API design
- You do not own the code or IP
- Fixed price from $80K after Roadmap
- HIPAA, PCI-DSS, SOC 2 built into every API
- Senior engineers only (10+ years avg)
- All infrastructure costs included in quote
- Documented API design (OpenAPI 3.0)
- You own full code, IP, and deployment keys
Our API development process: from idea to production
Every project follows four clear phases so you know what you are getting and when.
We start with a Roadmap phase that defines the API endpoints, data models, and deployment architecture. You get a fixed price and timeline before a single line of code is written.
Each iteration runs in 2-week sprints. You see working endpoints every 14 days. We deploy to staging after each sprint and to production after the final security review.
What ships with every API project
When you hire IRPR as your senior API development company, you are not just getting code. You get a production-ready system.
Every deliverable is defined in the Roadmap. There are no hidden items. You get exactly what you need to run your API in production from day one.
- Full source code in your private GitHub or GitLab repo
- OpenAPI 3.0 or GraphQL SDL documentation
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Performance benchmarks under load (e.g., 1000 req/s)
- OWASP Top 10 security audit report
- Postman collection with example requests
- Docker Compose setup for local development
- Deployment scripts for AWS ECS or Azure App Service
- Uptime monitoring configuration (PagerDuty, Datadog)
What we ship in this practice.
Payment API for a fintech startup
Built a PCI-DSS Level 1 compliant payment API that processes debit card transactions. Handled $2M in volume during the first month. Tech stack: Node.js, Express, Stripe, PostgreSQL, deployed on AWS ECS.

Built a FHIR R4 API that integrates with Epic and Cerner. Achieved HIPAA compliance and passed a security audit in 12 weeks. Tech stack: .NET Core 8, Azure FHIR, SQL Server, Azure DevOps.
User management API for a SaaS platform
Delivered a multitenant API supporting 500,000 users with role-based access control. Reduced user onboarding time from 3 days to 10 minutes. Tech stack: Ruby on Rails, PostgreSQL, Auth0, Heroku.
MLS data aggregation API for a real estate startup
Built a GraphQL API that aggregates data from 10+ MLS feeds into a single endpoint. Handles 2 million property records with sub-200ms query times. Tech stack: Node.js, GraphQL, AWS Lambda, DynamoDB.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices. You know the total cost before any code is written.
Senior engineers only
Our team averages 10+ years of experience. We do not outsource or use junior developers. Every API is designed and coded by engineers who have shipped production systems at scale.
Compliance built in, not bolted on
We have built HIPAA, PCI-DSS, and SOC 2 compliant APIs for healthcare, fintech, and enterprise clients. Compliance is part of the architecture, not an afterthought.
You own everything
Full source code, API documentation, deployment scripts, and IP are yours from day one. We do not license or resell your API. You can take it to any team.
Rapid MVP in 8-12 weeks
We ship a production-ready API in 8-12 weeks. That includes authentication, documentation, monitoring, and a CI/CD pipeline. You are live before most agencies finish planning.
Post-launch support included
Every project includes 30 days of post-launch support. We fix bugs, make minor changes, and help you hand off to your internal team. No extra cost.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
