You need a custom API built by developers who ship on time and on budget. IRPR delivers production-grade APIs with fixed pricing and full code ownership.
IRPR builds custom APIs for companies that need reliable backend services. We use Node.js, Python, Go, Postgres, Redis, Kafka, and cloud-native tools like Docker and Kubernetes.
A custom API development project ships in 8-12 weeks for an MVP with pricing from $80K to $250K. Every API is built to HIPAA, PCI-DSS, or SOC 2 standards as needed.
CTOs building internal APIs for microservices, product owners integrating third-party platforms, data teams needing ETL pipelines, and SaaS companies launching public APIs all hire us. They want a fixed price, a clear timeline, and full code rights.
Standard JSON-based API following REST principles. Built with Express.js or FastAPI and documented using OpenAPI 3.0.
Flexible query language API for modern frontends. Built with Apollo Server or Yoga, integrated with Postgres or MongoDB.
Event-driven API that sends real-time notifications to external systems. Uses Stripe or Twilio webhooks and Redis queues.
Persistent connection API for live data updates. Built with Socket.io or WebSocketSharp, used in chat and live dashboards.
Lightweight, isolated API for service-to-service communication. Uses gRPC or RabbitMQ and deployed on Kubernetes clusters.
Bridge API that connects your system to Salesforce, HubSpot, Stripe, or AWS. Handles rate limiting and data transformation.
Managed API layer for external consumers with authentication and rate limiting. Uses Kong or AWS API Gateway and OAuth2.
Batch or streaming API that extracts, transforms, and loads data between sources. Built with Airflow or Kafka Connect and Postgres.
Hiring the right developers for your custom API means faster time to market and lower risk.
A poorly designed API leads to integration headaches, security vulnerabilities, and costly rewrites. We have shipped over 200 products across 50 countries, and 98% of our custom API projects deliver on time with no scope creep.
Our developers write every API with automated tests, rate limiting, and monitoring from day one. You get a production-ready service that can handle thousands of requests per second without breaking.
Not all custom API development developers work the same way. Here's what you get with IRPR.
When you hire a generic agency, you often get junior devs, hourly billing, and vague timelines. The result is an API that works on paper but fails under load.
IRPR assigns senior engineers with 10+ years of experience. We scope everything in the Roadmap phase (week 2) and give you a fixed price. No surprise invoices, no delays.
We follow a clear 4-phase process to get your custom API from idea to production.
Every custom API development project starts with a 2-week Discovery sprint. You talk directly to a senior engineer who maps your data flows, endpoints, and security requirements.
The Roadmap phase (week 2) produces a fixed-price proposal with a full timeline. You can start coding in week 3 and have a working MVP in 8 to 12 weeks.
Every custom API we build includes these deliverables by default.
We don't just hand you code. You get everything needed to maintain and scale your API independently.
Our standard delivery includes source code, infrastructure as code, automated tests, and production monitoring.

We scope everything in the Roadmap phase and give you a locked-in price. No hourly billing, no surprise charges.
You own every line of code we write. No licenses, no hidden fees, no vendor lock-in. The repo is yours from day one.
Every developer on your project has 10+ years of experience. We don't staff juniors or offshore teams.
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the API architecture. No retrofitting after launch.
Your first working version ships in 8 to 12 weeks. You can demo it, test it, and start integrating before full release.
A single point of contact ensures clear communication, weekly demos, and no surprises. You talk to your PM every week.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
