Backend API Development VendorAPI Vendor
We build production-grade APIs for startups and enterprises. Fixed price, 8-12 week delivery, full code ownership.
IRPR is a backend API development vendor that builds APIs for web apps, mobile apps, and SaaS platforms. We use Node.js, Python (FastAPI, Django), Go, and PostgreSQL to create REST and GraphQL APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, database schema, CI/CD pipelines, and API documentation (OpenAPI/Swagger). Compliance is built in: HIPAA for healthcare, PCI-DSS for fintech, SOC 2 for SaaS.
Companies hire us when they need a senior-only team to build their backend from scratch or refactor a legacy API. Typical buyers are CTOs at funded startups, product managers at mid-market firms, and engineering leads at enterprises who need a reliable vendor, not a staffing agency.

Why You Need a Dedicated Backend API Development Vendor
A dedicated vendor builds your API right the first time, with production-ready code, documentation, and deployment scripts.
Most companies try to build APIs with in-house junior developers or offshore freelancers. That leads to inconsistent code, missing error handling, and security gaps. A backend API development vendor like IRPR brings a senior team that has shipped 200+ APIs across 50 countries. We use code reviews, automated testing, and CI/CD to ensure every endpoint is fast and secure.
When you hire IRPR as your vendor, you get a fixed price and a clear timeline. We start with a 2-week Roadmap phase where we define the API schema, endpoints, and data model. Then we build in 2-week sprints with full transparency. You own the code, the repo, and the deployment. No lock-in, no hidden fees.
IRPR vs Generic Development Shops
Most API vendors charge by the hour and hand over messy code. IRPR delivers a production-ready API with full documentation.
Generic development shops often use junior developers, change scope without notice, and deliver incomplete APIs. They may not handle authentication, rate limiting, or error logging. You end up paying more for bug fixes and rewrites.
IRPR assigns a senior architect to every project. We write unit tests, integration tests, and API documentation automatically. Our fixed price means no surprises. We also include deployment scripts for AWS, GCP, or Azure so your API is live from day one.
- hourly billing with no cap
- junior or mid-level developers
- no API documentation
- manual deployment only
- no error monitoring (Sentry)
- no security audit
- fixed price, no surprises
- senior engineers only (10+ years)
- OpenAPI/Swagger docs included
- CI/CD pipeline on GitHub Actions
- Sentry error tracking pre-configured
- OWASP security checklist applied
How We Build Your Backend API
Our process is designed to de-risk your project and deliver a production-ready API in weeks, not months.
We follow a 4-phase approach: Idea, Roadmap, Product, Release. The Idea phase is a free discovery call where we understand your requirements. The Roadmap phase (week 2) produces a detailed API specification, data model, and timeline. The Product phase (weeks 3-10) is where we build and test every endpoint. The Release phase (weeks 11-12) includes deployment, monitoring, and handover.
Every phase has clear deliverables. You see working endpoints every 2 weeks. We use feature flags to ship incrementally. By week 12, your API is live in production with monitoring, logging, and a runbook.
What Ships With Your API
Every API project includes these deliverables by default. No add-ons, no extra charges.
When IRPR builds your backend API, you get more than just code. We ship everything needed to run and maintain the API in production. This includes the source code, deployment scripts, monitoring configuration, and documentation.
You own all intellectual property. There is no license fee, no recurring vendor lock-in. The code lives in your GitHub or GitLab repo from day one. We also provide a 30-minute walkthrough for your team.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions with automated tests
- OpenAPI/Swagger documentation hosted on SwaggerHub
- Docker Compose and Dockerfile for local development
- Sentry error tracking pre-configured
- PostgreSQL or MongoDB schema migrations
- Authentication (JWT, OAuth2, or API keys)
- Rate limiting and request validation middleware
- Deployment scripts for AWS ECS or GCP Cloud Run
- 30-day post-launch support and bug fixes
What we ship in this practice.
Multi-Tenant SaaS API for a Fintech Startup
Built a REST API with Node.js, PostgreSQL, and Stripe. Handles 500K requests/day with per-tenant rate limiting. Reduced time to onboard new tenants from 2 weeks to 2 hours.

Created a FHIR-based API with Django, PostgreSQL, and AWS HealthLake. Passed HIPAA audit with zero findings. Enabled secure data exchange with 3 hospital systems.
Payment Gateway Integration API for an Ecommerce Brand
Integrated Stripe, PayPal, and Square into a single API using Node.js and TypeScript. Reduced payment processing errors by 90% and added 3 new payment methods in 4 weeks.
Inventory Sync API for a Logistics Company

Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write code.
Senior Engineers Only
Our team averages 12 years of experience. No junior developers, no bootcamp grads. Every engineer has shipped at least 10 production APIs. You get a senior architect on every engagement.
Full Code Ownership
You own the source code, the repo, and all IP from day one. No licenses, no recurring fees, no vendor lock-in. We deploy to your AWS or GCP account.
Built-In Compliance
We implement HIPAA, PCI-DSS, SOC 2, and GDPR controls by default. Our checklist covers encryption, access control, audit logging, and data retention. Auditors love our documentation.
8-12 Week Delivery
Most APIs ship in 8-12 weeks from kickoff. We use 2-week sprints with working demos. You see progress every sprint, not just at the end.
Production-Ready by Default
Every API ships with CI/CD, monitoring (Sentry, Datadog), logging, and a runbook. Your team can take over maintenance immediately. No handoff delays.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
