We build REST, GraphQL, and gRPC APIs for SaaS platforms, mobile backends, and data pipelines. Senior engineers only, fixed price, 8-12 week delivery.
IRPR is a custom API development firm that designs and builds production-grade APIs for web, mobile, and enterprise systems. We use Node.js, Python, Go, and Rust to create REST, GraphQL, and gRPC endpoints with PostgreSQL, Redis, and Kubernetes for scale.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. Our APIs pass PCI-DSS, HIPAA, SOC 2, and FERPA audits. We provide full documentation, Postman collections, OpenAPI specs, and 99.9% uptime SLAs.
CTOs hire us when their in-house team lacks API bandwidth. Product managers hire us to launch a new integration layer. Tech founders hire us to build the backend for their MVP. Enterprise architects hire us to unify legacy systems with modern APIs.
Stateless, resource-oriented APIs using Node.js, Express, or Python FastAPI with JWT auth and MongoDB or PostgreSQL.
Single endpoint, typed schemas with Apollo or Yoga. Supports real-time subscriptions and federated gateways.
High-performance, language-agnostic RPC using Protocol Buffers. Ideal for microservices and IoT backends.
Connect existing systems to third-party APIs (Stripe, Salesforce, Twilio, OpenAI) with error handling and retry logic.
Decoupled, independently deployable services with message brokers like RabbitMQ or Kafka and Docker orchestration.
WebSocket and Server-Sent Events APIs for live dashboards, chat apps, and collaborative tools using Socket.io or Pusher.
Private APIs for employee-facing tools, BI systems, and internal workflow automation with role-based access control.
Developer-facing APIs with API keys, rate limiting, usage analytics, and developer documentation portals using Swagger/OpenAPI.
Your business depends on APIs to connect customers, partners, and internal tools.
Pre-built API gateways and low-code tools can wire up simple integrations, but they break under high traffic, complex business logic, or strict compliance rules. A custom API development firm like IRPR builds APIs that handle 10,000 requests per second, pass HIPAA or PCI-DSS audits, and scale to millions of users.
APIs built with generic frameworks often lack proper error handling, rate limiting, or monitoring. IRPR includes Sentry error tracking, Datadog logging, and Prometheus metrics in every project. We also provide a full Postman collection and an OpenAPI spec so your team can test and integrate from day one.
Most agencies treat your API as a side project. IRPR treats it as the product.
Generic dev shops start coding in week 1 with no API contract, no threat model, and no performance budget. They deliver a monolithic endpoint that works on localhost but fails under load. Then they charge hourly for fixes.
IRPR starts with an OpenAPI spec and a performance benchmark agreed in week 2. We build stateless, horizontally scalable services with automated tests and CI/CD from day one. You get source code, infrastructure as code, and a 99.9% uptime SLA.
Four phases, each with a clear deliverable and a go/no-go decision.
IRPR uses a sprint-based process that keeps your team in the loop without slowing down our engineers. Every phase ends with a demo and a written acceptance sign-off.
You control the schedule. If you need to pause for a quarter, we pick up where we left off. No restart fees, no lost context.
We deliver more than code. You get the entire production stack.
Most agencies hand you a Git repo and disappear. IRPR gives you the runtime, the dashboards, and the runbook so your team can operate the API from day one.
We deploy to your AWS, GCP, or Azure account. You control the keys. We just provide the automation.
Built a RESTful API managing 50,000+ subscriptions with Stripe integration, usage metering, and proration. Reduced billing errors by 95%. Stack: PostgreSQL, Node.js, Stripe, Redis, Docker.
Created a GraphQL API for a telehealth app that serves 500+ clinics. All endpoints HIPAA-compliant with end-to-end encryption. Achieved 99.9% uptime. Stack: Python, FastAPI, PostgreSQL, AWS KMS.
Designed a PCI-DSS Level 1 API handling $2M/month in transactions. Included fraud detection, tokenization, and multi-currency support. Stack: Go, gRPC, PostgreSQL, Stripe, Redis.
Built a WebSocket API that updates inventory across 3 warehouses in under 200ms. Integrated with Shopify and ShipStation. Reduced overselling by 100%. Stack: Node.js, Socket.io, RabbitMQ, MongoDB.
Unified 4 legacy ERP systems into a single RESTful API service. Exposed 120+ endpoints for order management, inventory, and quality control. Cut data retrieval time from 30 minutes to 2 seconds. Stack: Python, FastAPI, PostgreSQL, Kafka.
Delivered a FERPA-compliant public API with rate limiting, usage analytics, and developer docs. 50+ third-party integrations in the first 6 months. Stack: Node.js, Apollo, Redis, GraphQL.
Every API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write any code.
We do not hire juniors. Every engineer on your project has 8+ years of backend experience. Your API is built by someone who has shipped at least 10 production APIs before.
We write the OpenAPI 3.0 spec and get your sign-off before writing a single line of code. Your team can start building integrations in parallel. No rework, no miscommunication.
We bake HIPAA, PCI-DSS, SOC 2, and FERPA controls into the architecture from day one. Audit preparation is included, not an add-on. We have passed 12 compliance audits with zero findings.
You own 100% of the source code, infrastructure config, and documentation. We deploy to your cloud account. You can fire us after week 1 and still have a running API.
Every 2 weeks you see a working, deployed endpoint with automated tests and monitoring. You can change priorities at the end of any sprint. No waterfall, no waiting for delivery day.
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.
