Hire a Custom API Development TeamAPI Development
Your product needs APIs that scale. We build them in 8-12 weeks with a fixed price.
IRPR builds custom APIs for SaaS platforms, mobile apps, and enterprise systems. We use Node.js, Go, Python, PostgreSQL, Redis, and Kafka to design and deploy REST, GraphQL, and gRPC APIs.
Every custom API project ships with API documentation (OpenAPI/Swagger), automated tests, rate limiting, and monitoring in 8-12 weeks. Pricing ranges from $80K to $250K depending on complexity. We support HIPAA, PCI-DSS, SOC 2, and GDPR compliance.
Founders hire us when their MVP needs a production-grade backend. CTOs hire us to replace a legacy API that can't scale. Product owners hire us to build an integration layer that connects their app to Salesforce, Stripe, or Shopify.
Types of software we ship.
REST API Development
Stateless HTTP APIs with JSON payloads. Built with Express.js, Fastify, or Django REST Framework.
GraphQL API Development
Flexible queries with Apollo Server or Hasura. Reduces over-fetching and under-fetching from mobile clients.
gRPC API Development
High-performance binary APIs using Protocol Buffers. Used for microservices and real-time systems.
Webhook API Development
Event-driven APIs that push data to your app. Integrates with Stripe, GitHub, Slack, and Twilio.
Third-Party API Integration
Connect your app to Salesforce, HubSpot, Shopify, QuickBooks, or any REST/SOAP API.
API Gateway Development
Centralized entry point with Kong or AWS API Gateway. Handles auth, rate limiting, and routing.
Real-Time API Development
WebSocket or Server-Sent Events APIs for chat, live dashboards, and collaborative tools.
Data API Development
APIs that expose database queries, ETL pipelines, or analytics results. Built with PostgREST or Hasura.
We build for every business type.

Why You Need a Dedicated Custom API Development Team
A well-designed API is the backbone of every modern application.
IRPR's API team has shipped over 200 products across 50 countries. We use Node.js, Go, Python, PostgreSQL, Redis, and Kafka to build APIs that handle 10,000 requests per second with 99.9% uptime. Every API includes OpenAPI documentation, automated tests, and rate limiting.
We start with a 2-week Roadmap phase where we define the API contract, choose the protocol (REST, GraphQL, or gRPC), and set up the CI/CD pipeline. After that, we build the API in 8-12 weeks with fixed pricing. No hourly billing, no scope creep.
The Difference Between IRPR and a Generic Dev Shop
Most API projects fail because of unclear contracts, slow delivery, and no post-launch support.
Generic dev shops often start coding without a clear API contract. They use hourly billing, which encourages slow work. They don't include documentation, tests, or monitoring unless you pay extra. And they rarely handle compliance like HIPAA or PCI-DSS.
IRPR does the opposite. We define the API contract in the Roadmap phase. We use fixed pricing so you know the cost upfront. We ship OpenAPI docs, automated tests, and Sentry error tracking by default. And we have built APIs for HIPAA, PCI-DSS, and SOC 2 environments.
- Starts coding without a clear API contract
- Uses hourly billing - no cost certainty
- No API documentation included
- No automated tests or CI/CD
- No monitoring or error tracking
- Rarely handles compliance (HIPAA, PCI-DSS)
- Defines API contract in the 2-week Roadmap phase
- Fixed pricing - you know the cost upfront
- OpenAPI / Swagger documentation included
- Automated tests and GitHub Actions CI/CD pipeline
- Sentry error tracking and uptime monitoring
- HIPAA, PCI-DSS, SOC 2 compliance built in
How IRPR Builds Your Custom API in 4 Phases
Our process ensures your API is secure, scalable, and documented.
We break every API project into four phases. Each phase has a clear deliverable and a fixed price. You see working software at the end of every phase.
Phase 1 is the Roadmap. Phase 2 is the MVP build. Phase 3 is the hardening and security review. Phase 4 is deployment and monitoring setup.
What Ships with Every Custom API Project
Everything you need to run and maintain your API in production.
Every API project includes documentation, tests, monitoring, and infrastructure as code. You own the source code from day one.
We deploy on AWS ECS, GCP Cloud Run, or your own servers. We use Terraform or Pulumi for infrastructure as code.
- Source code in your GitHub/GitLab repo
- OpenAPI / Swagger documentation
- Automated unit and integration tests (Jest, pytest)
- CI/CD pipeline on GitHub Actions or GitLab CI
- Rate limiting with Redis or API Gateway
- Authentication (JWT, OAuth 2.0, API keys)
- Sentry error tracking and performance monitoring
- Datadog or CloudWatch dashboards
- Infrastructure as code (Terraform or Pulumi)
- Post-launch support for 30 days
What we ship in this practice.
SaaS Platform API
Built a REST API for a subscription management platform. Handles 5,000 requests per second. Uses Node.js, PostgreSQL, Redis, and Stripe. Reduced payment failure rate by 40%.
Healthcare Data API
Built a HIPAA-compliant API for a telemedicine app. Uses Python, FastAPI, and FHIR standards. Reduced patient data retrieval time from 30 seconds to 2 seconds.
Ecommerce API Gateway
Built a GraphQL API gateway for a multi-vendor marketplace. Uses Apollo Server, PostgreSQL, and Shopify integration. Reduced page load time by 60%.
Real-Time Chat API
Built a WebSocket API for a collaboration tool. Uses Go, Redis Pub/Sub, and WebSockets. Handles 10,000 concurrent connections with 50ms latency.
Fintech Payment API
Built a PCI-DSS compliant REST API for a payment processing platform. Uses Node.js, PostgreSQL, and Stripe Connect. Handles $2M in monthly transactions.
IoT Data Ingestion API
Built a gRPC API for a manufacturing sensor network. Uses Go, Kafka, and InfluxDB. Ingests 1 million data points per minute with 99.99% reliability.
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 cost before we write a line of code.
Senior engineers only
IRPR hires no juniors. Every API is built by engineers with 7+ years of experience in Node.js, Go, Python, and cloud infrastructure. We don't outsource or subcontract.
API documentation by default
Every API ships with OpenAPI 3.0 documentation. Your team can start integrating immediately. No reverse engineering or guesswork.
Compliance ready
We have built APIs for HIPAA, PCI-DSS, SOC 2, and GDPR environments. We run security scans, audit logs, and data encryption by default.
99.9% uptime SLA
We deploy APIs on AWS or GCP with auto-scaling, load balancing, and multi-region failover. We monitor uptime with Datadog and alert on any degradation.
30-day post-launch support
After launch, we stay on for 30 days to handle bugs, performance tuning, and integration questions. You get direct Slack access to the team.
