Affordable Backend API Development AgencyBackend API
IRPR builds production-grade APIs for startups and scale-ups. 8-12 week delivery with a fixed price from $80K.
IRPR is an affordable backend API development agency that builds custom APIs using Node.js, Python, Go, and TypeScript. We design REST and GraphQL endpoints with PostgreSQL, Redis, and AWS Lambda for scalable, low-latency backends.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, logging, and documentation out of the box. Our APIs pass PCI-DSS, HIPAA, and SOC 2 compliance audits.
Founders building a SaaS MVP hire us to ship their backend in weeks. CTOs at mid-market companies hire us to replace legacy monoliths with microservices. Product managers at Series A startups hire us to build integrations with Stripe, Salesforce, and HubSpot.

What an affordable backend API development agency delivers
IRPR ships production-ready APIs with every feature you need to scale.
Our APIs include authentication via OAuth 2.0 or JWT, rate limiting with Redis, error tracking with Sentry, and automated deployment on AWS ECS or Lambda. Each endpoint is documented with OpenAPI 3.0 and tested with 95%+ coverage.
We build for compliance from day one. Healthcare projects get HIPAA-compliant logging and encryption. Fintech projects pass PCI-DSS Level 1 audits. Ecommerce APIs handle 10,000 requests per minute without breaking.
Why IRPR beats generic dev shops for backend API development
Most agencies overcharge and underdeliver. IRPR gives you senior engineers and fixed pricing.
Generic dev shops assign junior developers who learn on your dime. IRPR assigns senior engineers with 10+ years of experience who have shipped 200+ APIs. We write clean, documented code from day one.
We charge a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices. If the scope changes, we adjust the price before we start building.
