backend api development partnerdevelopment partner
We build production-ready backend APIs in 12-14 weeks. Fixed price from $80K.
IRPR is a backend API development partner that builds custom APIs using Node.js, Python (FastAPI), Go, or Java Spring. We design REST, GraphQL, and gRPC endpoints that handle millions of requests per day.
Every API project ships in 12-14 weeks with a fixed price between $80K and $250K. We cover compliance (HIPAA, PCI-DSS, SOC 2), rate limiting, caching, and database indexing. Source code is yours from day one.
We work with CTOs who need to replace a legacy monolith, product owners launching a SaaS MVP, engineering leads integrating third-party services, and compliance officers requiring audit-ready backends.
Types of software we ship.
REST API development
Full RESTful endpoints with OpenAPI specs. Supports JWTs, OAuth 2.0, and scoped access tokens.
GraphQL API development
Single endpoint with schema-first design. Apollo or Relay on Node.js, plus batch loading with DataLoader.
Real-time API (WebSockets)
Low-latency WebSocket servers for chat, live dashboards, and notifications. Powered by Socket.IO or AWS API Gateway.
Microservices API gateway
API gateway using Kong or NGINX. Routes traffic, handles auth, rate limits, and logs to Datadog.
Data ingestion API
High-throughput pipelines using Kafka or RabbitMQ. Parses CSVs, JSON, and XML into PostgreSQL or Snowflake.
Third-party API integration
Connect Stripe, Salesforce, HubSpot, Twilio, or 100+ other services. Handles webhooks, retries, and idempotency.
Admin dashboard backend API
Role-based admin APIs with CRUD, audit logs, and export endpoints. Built on Django REST or Express with Prisma.
Mobile app backend API
Backend APIs for iOS/Android apps. Offline sync, push notifications via Firebase, and token-based auth.
We build for every business type.
Healthcare
Fintech
Ecommerce

Why you need a backend API development partner
Building a secure, scalable backend API in-house can delay product launches by 6 months or more.
IRPR has shipped over 200 API-based products across 50 countries. Our senior engineers build backends that handle 10,000+ requests per second with 99.9% uptime. We use FastAPI, Express, and Spring Boot for speed and reliability.
A dedicated backend API development partner saves you 4-6 months of hiring and ramp-up. We deliver a production-ready API with CI/CD, monitoring, and documentation in 12-14 weeks. Your team can focus on frontend and product.
How IRPR compares to hiring a generic dev shop
Most dev shops start coding before understanding your API needs. IRPR does it differently.
A generic dev shop gives you a price after a one-hour call. They might use a junior team, skip documentation, and hand you code that doesn't scale. You own the code but not the hours you spent fixing bugs.
IRPR writes a detailed API specification in the Roadmap phase (week 2). You review endpoints, data models, and auth flows before we write a single line. Fixed price means no surprises.
- No API contract upfront
- Hourly billing that runs over
- Junior developers assigned to your project
- No monitoring or logging setup
- Generic authentication with no role system
- No documentation delivered
- OpenAPI spec signed off before coding
- Fixed price quoted in week 2
- Only senior engineers with 8+ years experience
- Datadog or New Relic monitoring included
- JWT + role-based access control (RBAC)
- Auto-generated docs via Swagger or Stoplight
Our backend API development process
Four phases from idea to production API.
We follow a proven process that reduces risk and keeps stakeholders aligned. Every phase ends with a deliverable you can review.
The timeline is 12-14 weeks for a typical API. Compliance audits add 2-3 weeks for HIPAA or PCI-DSS projects.
What ships with every API project
No handoff headaches. Every project includes production-ready infrastructure.
IRPR does not deliver unfinished code. You get a complete system that your team can run, monitor, and extend.
All projects include a 30-day post-launch support period. We fix bugs and answer questions.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker Compose and Dockerfile for local dev
- Sentry error tracking and alerting
- Datadog or New Relic performance monitoring
- Auto-generated API docs (Swagger or Stoplight)
- Load test script (k6 or Artillery)
- Database migration files and seed data
- Environment variables template and secrets guide
What we ship in this practice.
Telemedicine video API
Built a HIPAA-compliant WebRTC signaling API for a telemedicine startup. Handles 500+ concurrent video sessions. Uses Node.js, Redis, and AWS KMS for encryption. Reduced time-to-live by 14 weeks.
Payment orchestration API
Created a PCI-DSS Level 1 compliant payment gateway aggregator. Routes transactions through Stripe, Adyen, and Braintree. Processes $2M/month. Built on Go, PostgreSQL, and Vault for secrets.
Multi-warehouse inventory API
Designed a RESTful inventory API for an ecommerce brand with 3 warehouses. Syncs stock levels in real time via webhooks. Reduced overselling by 98%. Tech stack: Node.js, PostgreSQL, and RabbitMQ.
SaaS billing metering API
Architected a usage-based billing backend for a SaaS platform. Tracks API calls, storage, and compute per tenant. Integrates with Stripe for invoicing. Cut billing errors by 90%. Used FastAPI, Redis, and TimescaleDB.
MLS data integration API
Built an ETL pipeline that ingests MLS listings from 5 regional services. Normalizes data into a single schema and exposes via GraphQL. Updated every 30 minutes. Uses Python, Airflow, and Snowflake.
Student data API for LMS
Developed a FERPA-compliant REST API for a learning management system. Handles grade submission, enrollment, and attendance. Supports 10,000+ students per district. Stack: Django REST, MySQL, and Redis.
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. IRPR has completed 200+ projects on fixed price.
Senior engineers only
IRPR does not staff juniors. Every engineer has 8+ years of backend experience. You work with the same person from spec to deployment. Average tenure at IRPR is 4 years.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 backends by default. Our compliance checklist covers encryption at rest, audit logs, access controls, and vulnerability scanning. No retrofitting.
Documentation you can actually use
Every API ships with auto-generated Swagger docs, a Postman collection, and a README. Your frontend team can start integration on day one of deployment. No guesswork.
Load tested before launch
IRPR runs load tests using k6 or Artillery before every production deployment. We tune database queries, add caching, and optimize endpoints to handle 10x your expected traffic.
30-day post-launch support
After deployment, we stay on for 30 days. We fix bugs, answer questions, and help your team take over. Handoff includes a recorded walkthrough and written runbook.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
