Senior API Development PartnerAPI Development
We build secure, scalable APIs for your product. 200+ APIs shipped with fixed pricing and 12-week delivery.
IRPR is a senior api development partner that builds production-grade APIs using Node.js, Go, Python, and TypeScript. We deploy on AWS or GCP with PostgreSQL, Redis, and Kong for routing and rate limiting.
Every project ships with OpenAPI 3.0 documentation, k6 load testing, Datadog monitoring, and a CI/CD pipeline. Our standard timeline is 10-14 weeks with fixed pricing from $80K to $250K, and we comply with HIPAA, PCI-DSS, and SOC 2.
CTOs building core platform APIs hire us for reliability and speed. Product managers need us to integrate third-party services without breaking their roadmap. Engineering leads bring us in to refactor or scale existing APIs. Startup founders use us to launch API-first MVPs in under 12 weeks.
Types of software we ship.
REST API Development
Build stateless REST APIs with proper caching, versioning, and pagination. We use PostgREST or Express with JWT.
GraphQL API Development
Create flexible GraphQL APIs with Apollo Server and schema stitching. Reduces over-fetching for mobile clients.
gRPC API Development
Implement high-throughput gRPC services with Protocol Buffers. Ideal for internal microservices and real-time systems.
Third-Party API Integration
Connect your product to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP endpoint. Includes error handling and retry logic.
API Gateway & Management
Deploy Kong or AWS API Gateway for rate limiting, authentication, and logging. Centralized control for all your endpoints.
Microservices API Architecture
Design and implement a suite of microservices communicating via REST, gRPC, or event buses like Kafka.
Real-Time API with WebSockets
Build WebSocket or SSE based APIs for live dashboards, chat, and notifications. Uses Socket.io or native WS.
API Security & Authentication
Implement OAuth 2.0, JWT, API keys, and RBAC. Integrate with Okta, Auth0, or custom identity providers.
We build for every business type.
SaaS Platforms
Fintech
Healthcare
Ecommerce
IoT & Data
Why You Need a Senior API Development Partner
Building an API in-house often takes longer and costs more than expected.
IRPR has shipped over 200 APIs across 50 countries. Our average delivery time is 12 weeks from spec to production. We use OpenAPI 3.0 and Postman collections so your team can start integrating immediately.
Every API includes load testing with k6, monitoring with Datadog, and a security audit with SonarQube. We also deploy infrastructure as code using Terraform. Your code stays in your GitHub repo - we never ask for a licensing fee.
IRPR vs. Generic Development Shops
Not all API development partners deliver the same quality.
Generic shops often bill by the hour, skip documentation, and leave you with untestable code. IRPR works differently from day one. We give you a fixed price, full specs, and production monitoring.
Our senior engineers have 8+ years of experience each. We don't hire juniors. Every API project includes a dedicated solution architect who stays until launch.
- hourly billing with no cap
- no API documentation
- no load testing
- no production monitoring
- code stays with vendor
- scope creeps every sprint
- fixed price from the Roadmap phase
- OpenAPI 3.0 spec shipped with code
- load testing with k6 included
- Datadog and Sentry set up pre-launch
- full source code ownership transferred
- clear change order process
Our API Development Process
We follow a proven 4-phase approach to ship your API on time and on budget.
Every project starts with a specification phase where we define all endpoints, data models, and error handling. You get a mock server to validate before we write production code.
After approval, we build and test each endpoint with automated unit and integration tests. We then deploy to a staging environment where you can test with real data. Finally, we set up monitoring and hand over the repo.
What Ships With Your API
You get more than just code. Here is what every IRPR API project delivers.
We believe in shipping a complete package. Your team should be able to run, modify, and deploy the API without ever calling us again. That is why we include infrastructure code, documentation, and monitoring from the start.
All deliverables are stored in your private GitHub repository. You own everything - no vendor lock-in, no recurring fees.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline (GitHub Actions)
- Load testing report (k6)
- API monitoring (Datadog)
- Deployment scripts (Terraform)
- Postman collection
- Security audit report (SonarQube)
What we ship in this practice.
Payment API for Fintech Startup
Built a PCI-DSS compliant payment processing API handling 10,000 transactions per day. Reduced manual reconciliation by 90%. Tech stack: Go, PostgreSQL, Stripe, Kong.
Patient Data API for Telehealth

Real-Time Analytics API for SaaS
Built a WebSocket-based API powering live dashboards for 500 concurrent users. Processes 1,000 events per second. Tech stack: TypeScript, Kafka, WebSockets, Datadog.
Geolocation API for Logistics
Designed a REST API processing 1 million location pings per day with 99.9% uptime. Optimized route ETA calculations by 40%. Tech stack: Python, PostGIS, Redis, AWS.
Identity API for Media Platform
Implemented OAuth 2.0 and JWT authentication for 10,000 users. Integrated with Okta for SSO. Reduced login errors by 60%. Tech stack: Ruby on Rails, Okta, PostgreSQL.
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 10 years of experience. No juniors, no offshore mills. Every engineer has shipped at least 5 production APIs.
Own your code
Full IP ownership is transferred upon delivery. No licensing fees, no recurring royalties. The code, tests, and infrastructure are all yours.
API-first design
We write the OpenAPI spec before the first line of code. This means your frontend team can start building against mocks immediately.
Production monitoring included
Datadog dashboards and Sentry error tracking are set up before launch. You get real-time alerts and performance metrics from day one.
Compliance by default
We build HIPAA, PCI-DSS, and SOC 2 controls into every API. Our compliance checklist is part of the project plan, not an afterthought.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
