Premium REST API Development ConsultantsDevelopment Consultants
We build production-grade REST APIs that handle millions of requests per day. Ship your MVP in 12 weeks with a fixed price.
IRPR is a team of senior engineers who design and build premium REST APIs for startups and enterprises. We use Node.js, Python, Go, and Java with PostgreSQL, Redis, and Kafka to deliver APIs that scale to 100K+ requests per second.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, caching, and compliance (HIPAA, PCI-DSS, SOC 2) out of the box. You own 100% of the code.
We work with CTOs who need a secure API for their SaaS platform, product managers launching a mobile app backend, founders building a fintech MVP, and engineering leads integrating third-party services like Stripe and Salesforce.

Why hire premium REST API development consultants
IRPR has shipped 200+ REST APIs across 50 countries with a 98% on-time delivery rate.
A well-designed REST API saves months of development time. IRPR uses OpenAPI 3.0 for specification-first design, ensuring your API is documented, testable, and consistent from day one. We also implement rate limiting with Redis and automatic failover with Kubernetes.
Security is built into every endpoint. We enforce TLS 1.3, OAuth 2.0 with PKCE, and input validation using Joi or Zod. For regulated industries, we add HIPAA-compliant audit logs and PCI-DSS tokenization. Your data stays encrypted at rest and in transit.
What sets premium REST API development consultants apart
Not all API shops deliver production-grade code. Here is the difference.
Generic agencies hand you a REST API with no tests, no CI/CD, and no documentation. You spend months fixing bugs and refactoring. IRPR delivers a production-ready API with 90%+ test coverage, a CI/CD pipeline on GitHub Actions, and auto-generated Swagger docs.
We also include monitoring with Datadog, error tracking with Sentry, and a deployment runbook. Your team can deploy a new version within 10 minutes of merging a pull request. This saves an average of 20 hours per week during the first year of operation.
- No API specification upfront
- Zero automated tests
- No CI/CD pipeline
- No monitoring or alerting
- No documentation generated
- Hourly billing with scope creep
- OpenAPI 3.0 spec before coding
- 90%+ test coverage (Jest, Mocha)
- CI/CD on GitHub Actions
- Datadog monitoring + Sentry alerts
- Auto-generated Swagger docs
- Fixed price, no surprises
Our process for building premium REST APIs
We follow a 4-phase process that turns your idea into a live API in 12 weeks.
Phase 1 (Idea) takes 1 week. We map your business logic to RESTful resources, define endpoints, and validate with stakeholders. You get an OpenAPI 3.0 specification that your frontend team can start mocking against immediately.
Phase 2 (Roadmap) takes 1 week. We break the spec into 2-week sprints, assign a senior engineer and a QA engineer, and lock the price. You see the exact timeline and cost before any code is written.
What ships with your premium REST API
Every API project includes these 10 deliverables by default.
We deliver source code in your private GitHub repository with full commit history. You own everything. No licensing fees, no lock-in.
Each delivery includes a deployment runbook, a Postman collection, and a one-hour handover session with your engineering team.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog monitoring dashboard
- Auto-generated Swagger/OpenAPI docs
- Postman collection for all endpoints
- Deployment runbook (1 page)
- Rate limiting with Redis
- Authentication (OAuth 2.0 or JWT)
- One-hour handover session

Why teams hire us.
Fixed price, not hourly
Every premium REST 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 exact cost before we write a line of code.
Senior engineers only
IRPR hires only senior engineers with 8+ years of experience. No juniors, no offshore teams. Your API is built by someone who has shipped 10+ production APIs before.
Production-ready from day one
Every API ships with 90%+ test coverage, CI/CD, monitoring, and documentation. Your team can deploy to production within 10 minutes of the handover.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into every API from the start. No retrofitting, no security gaps. We handle audits and evidence collection.
You own all the code
There is no licensing fee, no platform lock-in, no recurring royalty. After the project, you own the full source code and all intellectual property. IRPR retains no rights.
12-week delivery guarantee
We ship your MVP in 12 weeks or less. If we miss the deadline, you pay nothing for the overage. This guarantee covers 98% of our projects.
