Senior Backend API Development StudioDevelopment Studio
We build production-grade APIs for 200+ products. Fixed price, 12-week delivery, full ownership.
IRPR builds production-grade backend APIs for startups and enterprises. We use Rust, Go, Node.js, and Python to deliver high-throughput, low-latency APIs.
Every project ships with source code, CI/CD, and monitoring. Delivery takes 8-12 weeks. Pricing starts at $80K and scales to $250K for complex systems. All APIs comply with HIPAA, PCI-DSS, or SOC 2 as needed.
CTOs need a senior API team without hiring overhead. Product owners need a scalable backend for their SaaS. VP Engineering needs to integrate legacy systems with modern APIs. Startups need an MVP API that can scale to millions of users.
Types of software we ship.
REST API
We design RESTful APIs with OpenAPI specs. Tools: Express.js, Flask, Django REST Framework.
GraphQL API
Build flexible GraphQL APIs with Apollo Server. Clients query exactly what they need, reducing over-fetching.
Microservices API
Decompose monoliths into microservices with message queues. Tools: RabbitMQ, Kafka, Docker.
Real-time API (WebSocket)
Real-time APIs for chat, live updates, IoT. Use Socket.io or WebSocket with Redis pub/sub.
Webhook API Integration
Receive and send webhooks reliably with retry logic and idempotency. Integrate Stripe, Slack, GitHub.
API Gateway Development
Centralized API gateway for auth, rate limiting, caching. Use Kong or AWS API Gateway.
Third-party API Integration
Connect your system to Salesforce, HubSpot, QuickBooks via their APIs. Custom adapters and sync.
Internal Backend Service
Build internal REST or gRPC services for your team. Protobuf, gRPC, and service discovery with Consul.
We build for every business type.
Professional services
Healthcare
Local services
Commerce
Nonprofits and education
Why senior engineers matter for your API
Senior engineers ship faster with fewer bugs.
A junior team might take 20 weeks and deliver fragile code. IRPR's senior engineers average 12 years of experience and follow best practices from day one.
Our APIs handle 100,000 requests per minute with 99.9% uptime. We write tests, document endpoints, and deploy with CI/CD automatically.
The difference with IRPR
Not all API development studios are equal. Here is how we compare.
Many agencies assign junior developers, charge by the hour, and deliver late. IRPR flips that model.
We assign senior engineers only, quote a fixed price upfront, and guarantee on-time delivery with a 98% track record.
- Junior devs learning on your project
- Hourly billing with no cap
- No CI/CD or monitoring
- Code ownership unclear
- Delays and scope creep
- No post-launch support
- Senior engineers with 10+ years experience
- Fixed price with defined scope
- CI/CD from day one
- Full code ownership
- On-time delivery (98% rate)
- 12-week post-launch support included
Our API development process
We follow a structured 12-week process from idea to production.
Every project starts with a 2-week Discovery phase where we map architecture, data models, and endpoints. You get a detailed Roadmap with fixed price.
Then we build in 2-week sprints with daily standups and weekly demos. Release happens in week 10-12 with full documentation and monitoring.
What ships with every API project
You get more than just code. Every project includes these deliverables.
We ship everything your team needs to maintain and scale the API. No hidden handoffs or missing pieces.
All deliverables are in your repo from day one. You control the keys and the roadmap.
- Source code in your GitHub/GitLab repo
- OpenAPI/Swagger documentation
- CI/CD pipeline with automated tests
- Sentry error monitoring
- Deployment scripts for AWS/GCP/Azure
- Load testing reports
- Postman collection
- API health check endpoint
- Rate limiting and auth middleware
- Team training and handoff session
What we ship in this practice.
Payment processing API for a Fintech startup
Built a PCI-compliant API handling 10,000 transactions/min. Tech: Go, PostgreSQL, Stripe Connect. Reduced payment failures by 40%.
Real-time inventory API for an ecommerce platform
Developed a WebSocket API for live inventory updates across 500 stores. Tech: Node.js, Redis, Socket.io. Cut inventory sync latency from 5 minutes to 2 seconds.
Patient data API for a telehealth platform
Created a HIPAA-compliant REST API for patient records and video calls. Tech: Python, FastAPI, AWS HealthLake. Enabled 50% faster patient onboarding.
ML model serving API for a SaaS analytics tool
Built a low-latency API to serve machine learning predictions to 100k users. Tech: Python, FastAPI, Kubernetes, TensorFlow Serving. Achieved 99.9% uptime and 50ms response time.
Property listing API for a real estate marketplace
Developed a GraphQL API aggregating MLS data from 20+ sources. Tech: Apollo Server, TypeScript, MongoDB. Reduced search load times by 60%.
Course enrollment API for an edtech platform
Built a scalable REST API handling 50k concurrent enrollments. Tech: .NET Core, Azure SQL, Redis. Enabled peak enrollment without downtime.
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.
Senior engineers only
Our team averages 12 years of backend experience. No juniors, no offshoring, no learning on your dime.
Full code ownership
You own the code from day one. We push to your repository, and you control the deployment keys.
12-week delivery guarantee
98% of our projects ship on time. If we miss the deadline, the next sprint is free.
Production-grade infrastructure
We include CI/CD, monitoring (Sentry, Datadog), and auto-scaling from the start. Your API is ready for production on day one.
Post-launch support included
We provide 12 weeks of post-launch support for bug fixes and minor updates. You get priority response within 4 hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
