Premium API Development FirmAPI Development
Ship production-grade APIs in 8-12 weeks with a premium API development firm. No junk code, no surprise bills, full code ownership from day one.
IRPR is a premium API development firm that builds custom APIs for SaaS platforms, fintech apps, healthcare systems, and ecommerce backends. We use Node.js, Python, Go, PostgreSQL, Redis, and both REST and GraphQL to deliver secure, high-performance APIs.
Every API project ships with a fixed price (typically $80K-$250K) and a timeline of 8-12 weeks. You get a detailed Roadmap in week 2, CI/CD pipelines, API documentation, and full compliance support for HIPAA, PCI-DSS, SOC 2, and GDPR.
We work with CTOs who need a reliable API for their product launch, VP Engineers at mid-market companies scaling their integrations, Product Managers building customer-facing APIs, and founders who want a secure backend without managing a dev team.
Types of software we ship.
RESTful API
Standard JSON over HTTP APIs built with Express.js or Django REST Framework. Optimized for mobile apps and third-party integrations.
GraphQL API
Flexible query-layer APIs using Apollo Server or Hasura. Reduces over-fetching and gives clients control over response data.
gRPC API
High-performance, binary-protocol APIs for microservice communication. We use Protobuf and Go to achieve sub-millisecond latency.
WebSocket API
Real-time, bidirectional APIs for live chat, notifications, and collaborative tools. Built with Socket.io or WebSocket on Node.js.
Payment Gateway API
Stripe, Square, or Braintree integrations with idempotent endpoints, PCI-DSS compliance, and idempotency keys to prevent double charges.
Third-Party API Integration
Connect your app to Salesforce, HubSpot, Shopify, or any external API. We build robust connectors with retry logic and rate limiting.
OAuth & Auth API
Secure authentication and authorization APIs using OAuth 2.0, OpenID Connect, and JWT. Supports social login and MFA.
Data Sync & ETL API
Batch or real-time data movement between systems. We design APIs that sync data to warehouses (Snowflake, BigQuery) or trigger workflows (Zapier, Make).
We build for every business type.
SaaS Companies
Fintech & Payments
Healthcare & HealthTech
Ecommerce & Retail
Enterprise & B2B
Why a Premium API Development Firm Matters
Average API projects fail because of scope creep, poor architecture, and no SLA.
IRPR has shipped over 200 API-based products across 50 countries. Our senior-only team writes every line of code internally and hands you a fully documented, production-ready API. We do not offshore or subcontract.
Our average API project delivers in 12 weeks with a 98% on-time rate. We enforce fixed pricing after a 2-week Roadmap phase, so you know the cost before we write a single line of code.
Generic API Shops vs. IRPR
Not all API development firms are equal. See how IRPR is different.
Most generic shops assign junior developers, use boilerplate code, and charge by the hour. You end up with an API that works on staging but fails under load. IRPR is built differently.
Our engineers average 10+ years of experience. We deliver code that passes load tests, security audits, and compliance reviews. You get a premium API development firm that treats your product like our own.
- Junior or offshore developers building your API
- Hourly billing with no cost cap
- No API documentation or Postman collections
- No load testing or performance benchmarking
- No compliance support (HIPAA, PCI, SOC 2)
- Code ownership often disputed
- Senior engineers only (10+ years average experience)
- Fixed price after Roadmap phase (no surprises)
- OpenAPI spec, Postman collections, and inline docs included
- k6 or Artillery load testing before go-live
- Built-in HIPAA, PCI-DSS, SOC 2, and GDPR compliance
- Full code ownership delivered to your GitHub/GitLab
Our API Development Process
From idea to production in 8-12 weeks with a clear, repeatable process.
We follow a four-phase framework: Idea, Roadmap, Product, Release. Every phase has deliverables you can review and approve before we move forward.
The Roadmap phase (week 2) produces a detailed technical specification, API contract, and fixed price. No code is written until you sign off on the plan.
Everything That Ships With Your API
When you hire IRPR, you get more than code. Every delivery includes these items by default.
Our goal is to make your team self-sufficient. We hand over every asset you need to maintain, extend, and document your API. No black boxes, no hidden dependencies.
You own everything. Source code, documentation, infrastructure scripts, and test suites are yours from day one.
- Source code in your private GitHub, GitLab, or Bitbucket repo
- OpenAPI 3.0 specification (Swagger UI ready)
- Postman collection with all endpoints and example requests
- CI/CD pipeline on GitHub Actions or GitLab CI with automated tests
- Docker Compose environment for local development
- Load test scripts (k6 or Artillery) with baseline numbers
- Sentry error tracking and performance monitoring setup
- Production deployment scripts for AWS, GCP, or Azure
- API usage analytics (via PostHog or custom dashboard)
- Written runbook for incident response and rollback
What we ship in this practice.

Why teams hire us.
Senior Engineers Only, No Juniors
Every engineer at IRPR has 10+ years of experience building production APIs. We do not assign juniors or outsource work. You talk directly to the person writing your code.
Fixed Price, Not Hourly
After the 2-week Roadmap phase, you get a fixed price quote. No hourly billing, no surprise invoices, no scope creep charges. The price we quote is the price you pay.
Production-Grade From Day One
We write code that passes load tests, security scans, and compliance audits before it reaches production. Every API ships with 99.9% uptime SLAs and monitoring out of the box.
Full Code Ownership
You own every line of code, every documentation file, every deployment script. We do not use proprietary frameworks or lock you into IRPR. The code is yours to modify, redeploy, or extend.
2-Week Risk-Free Discovery Phase
The first 2 weeks (Roadmap phase) cost a flat $8K and include a complete technical specification. If you do not like the plan, you walk away with the spec. No hidden fees.
Post-Launch Support Included
We monitor your API for 2 weeks after release, respond to incidents within 4 hours, and fix any bugs found during that period. After that, we offer optional maintenance retainers starting at $2K/month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
