Senior API Development TeamAPI Development
We build secure, scalable APIs for your product. 12-week MVP delivery, fixed price, full code ownership.
At IRPR, we assemble senior API development teams that build production-ready APIs using Node.js, Go, or Python with PostgreSQL or MongoDB. We design RESTful and GraphQL endpoints with OpenAPI 3.0 specs and automated testing.
Every project ships in 8-12 weeks for a fixed price between $80K-$200K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. You get full source code, CI/CD pipeline, and API documentation.
Our clients are CTOs at funded startups needing a core API, product managers integrating third-party services, and enterprise IT directors modernizing legacy systems. We also work with non-technical founders building their first product.
Types of software we ship.
Custom API Integration
Build connectors between SaaS tools like Salesforce, HubSpot, and Stripe with real-time sync and error handling.
REST API Development
Design stateless RESTful endpoints with JWT auth, rate limiting, and Swagger/OpenAPI documentation.
GraphQL API Development
Build flexible GraphQL schemas with Apollo Server, resolver patterns, and subscriptions for real-time updates.
Microservices API Gateway
Deploy API gateways using Kong or AWS API Gateway to route, throttle, and authenticate microservices.
Third-Party API Wrapper
Wrap complex external APIs (Twilio, Stripe, Slack) into clean, unified internal endpoints with caching and retry logic.
Payment API Development
Build PCI-compliant payment processing APIs integrated with Stripe, Braintree, or Adyen for recurring billing.
Healthcare API (FHIR)

Why Companies Hire a Senior API Development Team
Our team ships more than just endpoints.
We build APIs that handle millions of requests per day. Each API comes with rate limiting, caching, and monitoring out of the box.
Clients choose IRPR because we deliver fast and comply with strict industry standards. Our APIs pass HIPAA, PCI, and SOC 2 audits without extra cost.
How We Compare to Generic Dev Shops
Not all API teams are equal. Here is the real difference.
Generic shops hand off your API to junior developers who copy-paste code from tutorials. They miss error handling, security, and documentation.
IRPR assigns a senior engineer as lead architect. Every endpoint is peer-reviewed, documented in OpenAPI, and deployed with automated tests.
- Junior or offshore teams
- No API contract or spec
- Missing auth or rate limiting
- No monitoring in production
- Manual deployment
- No post-launch support
- Senior US-based engineers
- OpenAPI 3.0 spec from day one
- JWT, OAuth2, API key auth
- Sentry + Datadog monitoring
- CI/CD pipeline on GitHub Actions
- 12-month support included
How a Senior API Development Team Works with You
We follow a predictable 4-phase process.
Each phase has a fixed deliverable and a clear go/no-go decision point. You know exactly what ships and when.
We start with a Roadmap phase where we define every endpoint, data model, and integration. No guesswork.
What Ships with Your Senior API Development Team
Every API project includes these deliverables by default.
No hidden costs. No missing pieces.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification document
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests
- API documentation portal (Stoplight or Redoc)
- Auth system (JWT, OAuth2, or API keys)
- Rate limiting and throttling configuration
- Production monitoring with Datadog and Sentry
- Postman collection for all endpoints
- 12 months of post-launch support
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a PCI-compliant API using Node.js, Stripe, and PostgreSQL. Handles 10,000 transactions per day. Reduced chargebacks by 25% with custom fraud rules.
FHIR API for Telehealth Platform
Developed a HIPAA-compliant FHIR API using Python, FastAPI, and AWS HealthLake. Enabled real-time patient data exchange between 5 EHR systems.
GraphQL API for Ecommerce Marketplace
Designed a GraphQL schema using Apollo Server and MongoDB. Serves 500,000 product listings with sub-second query times. Increased mobile app performance by 40%.

Created a REST API (Ruby on Rails, PostgreSQL) to sync MLS listings across 3 brokerages. Reduced manual data entry by 20 hours per week.
Why teams hire us.
Fixed Price, No Hourly Surprises
We quote a fixed price after the Roadmap phase. No hourly billing, no scope creep charges. Over 200 projects delivered on budget.
Senior Engineers Only, No Juniors
Every project is led by a senior engineer with 10+ years experience. We do not staff juniors or offshore contractors.
Production-Ready APIs in 12 Weeks
From spec to deployment in 8-12 weeks. We ship with CI/CD, monitoring, and documentation. 98% of projects launch on time.
Compliance Built In, Not Bolted On
We design APIs to meet HIPAA, PCI, and SOC 2 standards from day one. No expensive retrofitting later.
Full Code Ownership
You own every line of code. We push to your GitHub repo. No licensing fees, no vendor lock-in.
12 Months of Free Support
Every project includes one year of bug fixes and updates. We handle production issues within 4 hours.
