Expert API Development CompanyAPI Development
Ship production-ready APIs in 12 weeks. Fixed price, no surprises.
IRPR builds secure, scalable APIs for startups and enterprises. We use Node.js, Go, Python, and TypeScript with Postgres, Redis, Kafka, and Docker to ship production-grade REST, GraphQL, and gRPC APIs.
API project timelines run 8 to 14 weeks with fixed pricing from $80K to $250K. Every API meets HIPAA, PCI-DSS, or SOC 2 compliance requirements. Code ownership transfers to you at delivery.
We work with CTOs launching a SaaS MVP who need a billing API, engineering leads migrating from REST to GraphQL, compliance officers at health tech companies who must pass a HIPAA audit, and product managers integrating Stripe, Salesforce, or HubSpot.
Types of software we ship.
REST API
Standardized HTTP endpoints for CRUD operations. Used by public web apps and mobile backends. Integrates with Postgres and Redis.
GraphQL API
Single endpoint with flexible queries. Reduces over-fetching. Built with Apollo Server, TypeGraphQL, and Prisma.
gRPC API
High-performance binary protocol for internal microservices. Uses Protocol Buffers and HTTP/2. Ideal for real-time data pipelines.
Webhook API
Event-driven callbacks that push data to external services. Used for order confirmations, payment notifications, and CI/CD alerts.
Payment API
PCI-DSS compliant endpoints for Stripe, Braintree, or Adyen. Handles subscriptions, invoicing, and refund workflows.
Healthcare API
HIPAA compliant FHIR and HL7 endpoints for EHR integration. Used by telemedicine platforms and clinic management software.
Third-party integration API
Middle-layer APIs that connect Slack, Salesforce, HubSpot, or Shopify to your system. Handles rate limiting and OAuth2.
Internal microservice API
Private gRPC or REST endpoints for service-to-service communication within a Kubernetes cluster. Includes auth, logging, and monitoring.
We build for every business type.
SaaS platforms
Fintech companies

Why choose an expert API development company
Most development shops hand you code. IRPR hands you a production API with documentation, monitoring, and a 99.9% uptime guarantee.
In 2025, an API is not just endpoints. It needs rate limiting, authentication, error handling, logging, and versioning. IRPR starts every project with a 2-week Roadmap phase that produces a detailed API spec, data model, and test plan before a single line of production code is written.
We have shipped over 200 APIs. Our senior engineers average 10+ years of experience. Every project follows the same four-phase process: Idea, Roadmap, Product, Release. You know the price, timeline, and deliverables before we build.
How IRPR differs from a generic dev shop
A generic shop sells hours. IRPR sells a fixed-price API that passes HIPAA, PCI, or SOC 2 audit.
Generic dev shops start coding on day one with no spec. You pay for discovery, rewrites, and scope creep. IRPR uses a 2-week Roadmap phase to lock the API contract, data model, and QA criteria. The price is fixed. The timeline is fixed.
We also handle deployment. Every API ships with CI/CD via GitHub Actions, Docker containers on AWS ECS or Kubernetes, Sentry error tracking, and a PagerDuty alerting channel. Your team gets a fully monitored production service.
- Hourly billing with no cap
- No API spec before coding
- No compliance documentation
- Code dump with no deployment
- No monitoring or alerting
- Unclear code ownership
- Fixed price from $80K
- Full API spec by week 2
- HIPAA, PCI, SOC 2 compliance docs
- CI/CD pipeline and containerized deployment
- Sentry + PagerDuty monitoring included
- Full IP and code ownership
How IRPR builds an expert API
Four phases. No surprises. Each phase ends with a deliverable you can review and approve.
The Idea phase is your discovery call. We listen to your problem, business goal, and compliance needs. Within 72 hours you get a project proposal with a price range and timeline.
The Roadmap phase takes two weeks. We produce a full API contract, database schema with Prisma or TypeORM, integration plan, and a written test plan. You approve the Roadmap document before we start coding.
What ships with every API project
You get more than code. Every project includes infrastructure, documentation, and operational tooling.
We do not drop a zip file over email. Every API project deploys to your cloud account with a working CI/CD pipeline. Your team can start testing on day one of the Release phase.
Documentation is auto-generated from the code. We use OpenAPI/Swagger for REST and GraphQL Schema for GraphQL. A Postman collection is included for manual testing. All source code is in your GitHub, GitLab, or Bitbucket repo.
- Source code in your private GitHub repo
- OpenAPI 3.0 spec or GraphQL schema
- Postman collection for all endpoints
- CI/CD pipeline via GitHub Actions
- Docker container ready for deployment
- Sentry error tracking with Slack alerts
- Unit tests with Jest or Mocha (80%+ coverage)
- Integration tests with SuperTest or Playwright
- Rate limiting and JWT authentication
- Database migration scripts (Prisma or TypeORM)
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly billing
Every API project has a fixed price locked in the Roadmap phase. No hourly rates, no time tracking, no surprise invoices. You approve the scope and the price before we write code.
Senior engineers only, no juniors
Our engineers average 10+ years of experience. We do not staff juniors or offshore teams. Every line of code is written by a senior engineer who has shipped production APIs for companies like Cisco and Verizon.
Compliance built in, not bolted on
HIPAA, PCI-DSS, and SOC 2 requirements are part of the architectural design. We include audit logs, encryption at rest and in transit, access controls, and compliance documentation without extra fees.
Full code ownership from day one
All source code, documentation, and infrastructure scripts are in your repo. We never charge licensing fees. Your team can take over or extend the API immediately after release.
CI/CD and monitoring included
Every API ships with a GitHub Actions pipeline, Docker containers, Sentry error tracking, and PagerDuty alerting. You get a production-grade deployment, not a developer laptop.
12-week timeline guarantee
APIs ship in 8 to 12 weeks from project kickoff. We have a 98% on-time delivery rate. If we miss the deadline, we communicate early and adjust scope within the fixed price.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
