Leading API Development Partner for Scalable SystemsAPI Development
We architect and build APIs that power your product. From REST to GraphQL, from MVP to enterprise scale.
IRPR builds custom APIs for SaaS platforms, fintech systems, healthcare applications, and ecommerce backends. We use Node.js, Python, Go, and Java with PostgreSQL, Redis, Kafka, and cloud-native services on AWS, Azure, or GCP.
A typical API project ships in 8-12 weeks for an MVP, with fixed pricing between $80K and $250K. We support HIPAA, PCI-DSS, and SOC 2 compliance, including data encryption, audit logs, and role-based access control.
Our clients include SaaS founders launching a new product, enterprise architects modernizing legacy systems, product managers at mid-market companies needing a scalable backend, and startups building their first API-first product.
Types of software we ship.
REST API
Stateless HTTP endpoints using JSON. Built with Express.js, FastAPI, or Spring Boot. Includes Swagger/OpenAPI docs.
GraphQL API
Single endpoint with flexible queries. Uses Apollo Server, Hasura, or Relay. Reduces over-fetching and under-fetching.
gRPC API
High-performance RPC using Protocol Buffers. Ideal for microservices communication. Uses Go, C#, or C++.
WebSocket API
Real-time bidirectional communication for chat, live updates, and streaming. Built with Socket.io, ws, or SockJS.
Serverless API
Auto-scaling functions on AWS Lambda, Azure Functions, or Cloudflare Workers. Pay per request, no server management.
API Gateway
Centralized entry point with rate limiting, auth, caching. Uses Kong, AWS API Gateway, or NGINX. Manages multiple backends.
Microservices API
Decoupled services communicating via APIs. Docker, Kubernetes, and service mesh. Enables independent deployments and scaling.
SOAP API
Structured XML-based protocol for enterprise integrations. Supports WS-Security, XSD schemas. Used in banking and legacy systems.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Logistics
Why Partner with IRPR for API Development
We have shipped over 200 production APIs across 50+ countries, delivering on time and within budget.
Every API we build is designed for scalability, security, and maintainability. Our senior engineers use modern practices like contract-first design, automated testing, and CI/CD from day one.
We have delivered APIs for healthcare platforms handling PHI under HIPAA, fintech systems processing payments under PCI-DSS, and SaaS products serving thousands of concurrent users.
What Sets IRPR Apart from Generic Dev Shops
Most agencies treat APIs as an afterthought. We treat them as the product.
Generic dev shops often skip API design docs, neglect error handling, and deliver undocumented endpoints. They use junior developers who copy-paste from Stack Overflow, leading to technical debt and security holes.
IRPR assigns senior engineers only. We produce OpenAPI specs before writing code, use automated contract testing, and provide detailed API docs and Postman collections with every delivery.
- No API design review
- Junior developers on your project
- No automated testing for endpoints
- Missing error codes and rate limits
- No documentation or Postman collections
- Hourly billing with vague estimates
- OpenAPI 3.0 spec before code
- Senior engineers only (10+ years avg.)
- Automated integration + contract tests
- Standard error responses, rate limiting, pagination
- Full API docs with Swagger UI and Postman
- Fixed price up front, no surprises
Our API Development Process: From Spec to Ship
We follow a repeatable 4-phase process that de-risks your investment.
Phase 1 is the Roadmap: we define the API contract, data models, and endpoints. Phase 2 is Product: we build the core endpoints with test coverage. Phase 3 is Release: we deploy to staging, run load tests, and finalize docs.
Every phase includes a review milestone. You see working endpoints after 3-4 weeks. No waiting 6 months for a first demo.
What You Get with Every API Project
Every deliverable is production-ready and fully owned by you.
We ship more than code. You get the infrastructure, documentation, and tooling to run your API without depending on us. No vendor lock-in.
- Source code in your private Git repository (GitHub, GitLab, or Bitbucket)
- OpenAPI 3.0 specification with Swagger UI
- Postman collection with example requests
- CI/CD pipeline (GitHub Actions, GitLab CI, or CircleCI)
- Dockerized deployment with docker-compose and Dockerfile
- Infrastructure as code (Terraform or CloudFormation)
- API monitoring and error tracking (Sentry, Datadog)
- API keys and authentication (JWT, OAuth2, API Key)
- Rate limiting and throttling configuration
- Unit, integration, and contract test suite
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a Stripe-compatible API to handle subscriptions, invoicing, and payout reconciliation. Reduced manual finance work by 15 hours per week. Tech stack: Node.js, PostgreSQL, Stripe, gRPC, Kubernetes.

Order Management API for Omnichannel Retail
Created a unified API for inventory, orders, and shipping across web, mobile, and POS. Cut order processing time by 40%. Tech stack: Python FastAPI, MySQL, RabbitMQ, Shopify API.
Multi-tenant SaaS API for Analytics Platform
Designed a REST API with per-tenant rate limiting and custom roles. Onboarded 200+ customers in 3 months. Tech stack: Ruby on Rails, PostgreSQL, Sidekiq, AWS API Gateway.
Route Optimization API for Logistics Company
Built a real-time routing API using OSMR and custom solver. Reduced delivery times by 18%. Tech stack: Go, Redis, GraphHopper, Google Maps API, Docker Swarm.
Content Moderation API for Social Media Platform
Delivered a machine learning-powered API to flag toxic comments and images. Analyzes 1M+ items daily. Tech stack: Python, TensorFlow, AWS Rekognition, Kafka, Elasticsearch.
Why teams hire us.
Fixed Price, Not Hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a single line of code.
Senior Engineers Only
We assign engineers with an average of 10+ years of experience. No junior developers. Every code review is done by a senior architect. Our team includes ex-FAANG engineers who have built APIs at scale.
8-12 Week Delivery
We ship a working API in 8 to 12 weeks. The first endpoints are live on staging by week 3. Faster than hiring internally (which takes 3 months just for recruiting).
Full Code Ownership
You own all source code, specs, and infrastructure scripts. No licenses, no royalties. You can take the code to any other team after delivery. We never lock you in.
HIPAA, PCI, SOC 2 Compliance
We build APIs that meet HIPAA, PCI-DSS Level 1, and SOC 2 Type II standards. Includes encryption at rest and in transit, audit logs, role-based access, and penetration testing.
Dedicated Product Manager
Every project has a product manager who handles communication, sprint planning, and backlog. Your engineers focus on code; the PM ensures timelines and requirements stay on track.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
