We build secure, scalable APIs that connect your systems. Get a fixed-price MVP in 12 weeks.
IRPR is a professional custom API development studio. We design and build RESTful and GraphQL APIs using Node.js, Python, Go, and PostgreSQL. Every endpoint is defined with an OpenAPI specification and tested for security.
Our delivery model is fixed price and timeline. For $80K-$250K, you get a production-ready API MVP in 8-12 weeks. We work under HIPAA, PCI-DSS, and SOC 2 compliance to meet your industry requirements.
We work with SaaS founders building API-first products, CTOs migrating from monolithic backends, and fintech startups creating payment APIs. Each buyer needs a reliable partner who ships on time without surprises.
Stateless endpoints with JSON responses. We use Express.js and Postman collections for clear documentation.
Flexible queries and subscriptions. Apollo Server and TypeGraphQL for type-safe schemas.
Unify multiple services behind a single gateway. Kong or Envoy for routing, rate limiting, and authentication.
Connect to Stripe, Salesforce, Twitter, or 200+ other services. We handle auth, webhooks, and data mapping.
Push updates to frontends and devices. Socket.IO or raw WebSockets with Redis Pub/Sub for low latency.
Expose product data to partners with API keys and usage plans. AWS API Gateway or Kong with developer portals.
Internal gRPC or REST services for data exchange between microservices. Protobuf for binary serialization.
Build a developer-facing API with documentation, versioning, and analytics. Stoplight or ReadMe for docs.
Building a reliable API requires more than writing routes. It demands architecture decisions that affect scaling, security, and maintenance.
IRPR has shipped over 200 custom APIs for clients in 50 countries. Our senior engineers use OpenAPI specs, automated testing, and CI/CD pipelines to deliver consistent quality. Each API includes rate limiting, authentication, and monitoring from day one.
We follow a proven process: Discovery (2 weeks) to map your data model and endpoints, then a fixed-price Roadmap (1 week), followed by 8-12 weeks of development. You get a production-ready API with source code and full documentation.
Not every development agency can build APIs that are production-ready from day one. Here is how we compare.
Generic shops treat API development like any other feature. They skip automated testing, neglect rate limiting, and deliver without documentation. This leads to downtime and expensive rewrites.
IRPR treats APIs as products. We design with contract-first approach, write tests for every endpoint, and deploy with monitoring and alerting. The result is an API that scales from day one.
We break down every custom API project into four clear phases. Each phase has a fixed output and price.
Phase 1: Discovery (2 weeks). Our engineers map your data sources, define endpoints, and create an OpenAPI specification. You review and approve the spec before any code is written.
Phase 2: Roadmap (1 week). Based on the approved spec, we produce a detailed build plan with a fixed price and 12-week timeline. You sign off on the roadmap, and we start development.
When you hire IRPR as your professional custom API development studio, you get more than code. You get a production-ready system.
Every project includes full source code, API documentation, automated tests, and deployment scripts. We also provide a runbook for your team to operate the API independently.
Built a PCI-DSS compliant API that processes ACH and credit card payments. Reduced transaction failures by 30% using idempotency and retry logic. Tech stack: Node.js, Stripe API, PostgreSQL, Redis.
Developed a FHIR R4 API to sync patient records between a telehealth app and three EHR systems. Integrated with Epic and Cerner APIs in 8 weeks. Tech stack: Python, FastAPI, FHIR, SQLAlchemy.
Created a high-throughput API for a multi-channel retailer to sync 10,000 orders per hour between Shopify, Amazon, and a custom WMS. Cut order processing time by 60%. Tech stack: Go, gRPC, RabbitMQ, MongoDB.
Designed a WebSocket API for a freight company to stream GPS coordinates from truck drivers to dispatchers. Reduced tracking resolution from 30 minutes to under 5 seconds. Tech stack: Node.js, Socket.IO, Redis, AWS IoT.
Built an API gateway for a B2B SaaS platform that lets 20+ partners integrate with custom auth and rate limits. Onboarded 15 new partners in the first quarter. Tech stack: Kong, Python, PostgreSQL, OAuth2.
Aggregated pricing and availability from 3 airline and 2 hotel providers into a single search API. Processes $2M in bookings monthly with 99.9% uptime. Tech stack: Node.js, Redis, GraphQL, Apollo Federation.
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
IRPR hires only engineers with 8+ years of experience. No juniors. Your API is built by someone who has shipped production systems to millions of users.
We integrate HIPAA, PCI-DSS, SOC 2, and GDPR requirements into the architecture from day one. Audits become paperwork, not rework.
Our standard MVP timeline is 12 weeks. For 98% of projects, we deliver on or before that date. If we are late, we discount the final milestone.
You own the source code, documentation, and all IP. There are no licensing fees or restrictions. We retain no rights to your product.
Our team operates across 10 time zones with overlapping hours in New York, London, and Singapore. You get daily progress and real-time Slack communication.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
