Expert Backend API Development TeamBackend API
We build production-ready APIs for your product. Launch in 8-12 weeks with a fixed price.
IRPR builds expert backend API development teams for products that demand reliable, scalable, and secure APIs. We use Node.js, Python, Go, AWS Lambda, and PostgreSQL to design and implement REST, GraphQL, and microservice-based APIs. Every API is production-ready from day one.
Our API projects ship in 8-12 weeks with a fixed price typically between $80K and $250K. Deliverables include source code, CI/CD pipelines, OpenAPI documentation, and load-tested endpoints. We also handle compliance certifications such as SOC 2, HIPAA, and PCI-DSS as needed.
CTOs at funded startups hire us to accelerate their backend without growing headcount. Product managers at mid-market companies hire us to build integration APIs for existing platforms. Enterprise architects hire us to modernize legacy API layers. Founders with a new product idea hire us to build the MVP backend.
Types of software we ship.
REST API Development
Stateless JSON APIs using Node.js or Python with PostgreSQL. Designed for scalability and third-party consumption. Includes rate limiting and caching.
GraphQL API Development
Flexible GraphQL endpoints built with Apollo Server. Single query resolves multiple data sources. Ideal for mobile apps and complex UIs.
Microservices API Architecture
Containerized services using Docker and Kubernetes. Each service has its own database and API contract. Enables independent deployment and scaling.
Real-Time API (WebSocket)
WebSocket and Server-Sent Events for live data. Built with Go or Node.js. Handles 1M+ concurrent connections with Redis pub/sub.
Third-Party API Integration
Plug into Salesforce, HubSpot, Stripe, Slack, or any REST/SOAP service. Includes retry logic, webhook handlers, and rate limit management.
Payment API Development
PCI-compliant payment APIs using Stripe, Braintree, or Adyen. Handles subscriptions, invoicing, and multi-currency transactions.
Data API (ETL / Analytics)
APIs that aggregate, transform, and expose data from multiple sources. Uses Apache Kafka, Airflow, or custom pipelines. Supports JSON, CSV, and Parquet.
Authentication API (OAuth 2.0 / JWT)
Secure identity and access management APIs. Implements OAuth 2.0, OpenID Connect, and JWT. Integrates with Auth0, Okta, or custom providers.
We build for every business type.
Health Tech
Fintech
Ecommerce
SaaS Platforms

Why a Dedicated Backend API Team Matters
Your API is the backbone of your product. It must be fast, reliable, and secure from day one.
IRPR has shipped over 200 backend APIs for startups and enterprises across 50 countries. We follow a repeatable process that starts with a 2-week Roadmap to define endpoints, data models, and integration contracts. Every API goes through automated load testing and security scanning before release.
Our team of senior engineers uses clean architecture patterns, writes unit and integration tests, and produces OpenAPI documentation that third-party developers can actually use. We also set up API monitoring with Datadog or Sentry to catch issues before your users do.
IRPR vs. a Generic Dev Shop
Not all API teams deliver the same quality. Here is the difference.
Generic agencies often start coding without a clear roadmap. They use hourly billing, change requirements without notice, and leave you with undocumented code. IRPR does the opposite: we fix the scope and price in week 2, and we deliver everything your team needs to maintain the API.
We have a track record of backend APIs that handle millions of requests per day. Our engineers have built APIs for fintech (PCI-compliant), healthcare (HIPAA-compliant), and ecommerce platforms with 99.9% uptime.
- Starts coding before defining the API contract
- Hourly billing with no cap
- No load testing or security scanning
- Little to no documentation
- Code ownership is unclear
- Long timelines with constant delays
- 2-week Roadmap defines all endpoints and data models
- Fixed price agreed in week 2
- Automated load testing and OWASP scanning
- OpenAPI/Swagger documentation delivered
- Full source code in your repository
- 8-12 week delivery with daily standups and weekly demos
Our 4-Phase Backend API Development Process
From idea to API in weeks, not months. Every phase has clear deliverables.
IRPR follows a four-phase framework: Idea, Roadmap, Product, Release. For API projects, this means we start with a Discovery call to understand your data sources and consumers, then produce a detailed API specification during the 2-week Roadmap phase.
The Build phase is 6-8 weeks where we implement endpoints, write tests, set up CI/CD, and integrate with your chosen services. The Release phase includes deployment, monitoring setup, and a two-week warranty period.
What Ships with Every Backend API
You get more than just code. Every project includes everything your internal team needs to run and extend the API.
IRPR has refined its delivery checklist over 200+ projects. We know what enterprise teams need to maintain an API in production. That is why we include infrastructure-as-code, monitoring dashboards, and developer documentation.
The checklist below covers the default deliverables for every expert backend API development project. If you need additional items like HIPAA compliance documentation or custom reports, we can include them in the scope.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Swagger/OpenAPI documentation
- Postman collection with example requests
- Docker configuration for local development
- Deployment scripts for AWS, GCP, or Azure
- Sentry error tracking integrated
- Load testing results (k6 or Artillery)
- API monitoring dashboard setup (Datadog)
- Two-week post-launch warranty and support
What we ship in this practice.
Fintech Payment Processing API
Built a PCI-compliant payment API for a lending platform. Handles 10,000 transactions per minute with AVS and 3DS verification. Tech stack: Node.js, PostgreSQL, Stripe Connect. Outcome: transaction processing time reduced by 40%.
Healthcare Data Exchange API
Developed a FHIR-based API for a telemedicine startup. Exchanges patient records with EHR systems via a single endpoint. Tech stack: Python, Flask, AWS HealthLake. Outcome: eliminated 10 hours per week of manual data entry.
Ecommerce Product Search API
Created a GraphQL API for a retail brand with 500K SKUs. Supports faceted search, autocomplete, and personalized recommendations. Tech stack: Elasticsearch, Redis, Apollo Server. Outcome: search speed improved by 200%.
Real-Time Messaging API
Built a WebSocket API for a collaboration platform. Supports 1 million concurrent connections with low-latency message delivery. Tech stack: Go, Redis pub/sub, WebSocket. Outcome: platform scaled to 2M users without downtime.
Third-Party Integration Hub API
Designed an integration API that connects a SaaS product to 15 external services (Slack, Salesforce, HubSpot, etc.). Tech stack: Node.js, Kafka, Docker. Outcome: integrated 15 services in 6 weeks versus estimated 12 weeks in-house.
Subscription Management API
Built a billing API with usage-based pricing for a B2B SaaS. Includes dunning, invoicing, and revenue recognition. Tech stack: Python, Django, Stripe. Outcome: reduced churn by 20% through proactive billing alerts.
Why teams hire us.
Fixed price, not hourly billing
IRPR provides a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Full code ownership
Every line of code we write belongs to you. We deliver the source code in your GitHub repository with no licenses or royalty fees. You can deploy, modify, or sell it freely.
8-12 week delivery guaranteed
We ship production-ready APIs in 8-12 weeks. Our process is designed for speed without cutting corners. 98% of our projects deliver on time.
Senior engineers only
Every IRPR engineer has 10+ years of experience in backend development. No junior developers. We assign a lead architect who owns the technical direction of your API.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Our teams implement encryption, audit logs, access controls, and BAA agreements without asking for extras.
Transparent daily process
You get daily standup notes, a private Trello board, and weekly demo videos. No black box. We use the same tools your internal team would use: GitHub, Slack, Jira.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
