Senior Backend API Development TeamDevelopment Team
Build scalable APIs with senior engineers who ship in 12 weeks. Fixed price, full compliance, zero surprises.
IRPR builds production-ready backend APIs with senior engineers using Node.js, Go, Python, PostgreSQL, Redis, and Kubernetes. We design RESTful and GraphQL endpoints, implement authentication flows, and set up CI/CD pipelines on GitHub Actions.
Every project ships in 8-12 weeks with a fixed price between $80,000 and $250,000. We handle HIPAA, PCI-DSS, and SOC 2 compliance for healthcare, fintech, and enterprise clients. Source code transfers to your repository at the end.
Typical buyers include CTOs at Series A startups needing a scalable API foundation, engineering managers at healthcare tech companies requiring HIPAA-compliant data exchange, product leads at fintech firms integrating payment gateways, and founders who want an API-first SaaS MVP.
Types of software we ship.
RESTful API Development
Build resource-oriented APIs with versioning, pagination, and status codes. Uses Express.js, Fastify, or Django REST Framework.
GraphQL API Development
Schema-first APIs with Apollo or Hasura. Supports real-time subscriptions and efficient data fetching for mobile clients.
Microservices API Design
Decoupled services communicating via gRPC or message queues (RabbitMQ, Kafka). Each service runs in its own Docker container.
API Gateway Implementation
Single entry point with Kong or AWS API Gateway. Rate limiting, authentication, and request transformation in one layer.
Third-Party API Integration
Connect your platform to Stripe, Twilio, Salesforce, or HubSpot using official SDKs. Webhook handling and retry logic included.
Real-Time API with WebSockets
Push notifications, live dashboards, and chat using Socket.io or AWS WebSocket API. Scales to thousands of concurrent connections.
API Security and Authentication
OAuth 2.0, JWT, API keys, and role-based access control. Penetration testing and OWASP top 10 checks are standard.
API Documentation and Testing
Auto-generated OpenAPI specs, Postman collections, and integration tests. Continuous testing in CI/CD with Newman or Supertest.
We build for every business type.

Our Track Record in Senior Backend API Development
IRPR has shipped over 200 backend APIs for companies across 50 countries, maintaining a 98% on-time delivery rate.
Every API we build goes through a standard pipeline: design review, implementation with full test coverage, automated CI/CD, and deployment to AWS, GCP, or Azure. We use Sentry for error tracking and Datadog for monitoring, ensuring uptime above 99.9%.
Our clients range from early-stage startups to enterprises with existing compliance requirements. In the fintech space alone we have delivered over 30 PCI-DSS certified APIs that process millions of transactions per month.
What Makes Senior Backend API Development Different
Most agencies send junior or mixed teams. IRPR assigns senior engineers only, and we back it with a fixed price and full IP transfer.
Generic dev shops often hide behind hourly billing and unclear ownership. They may have one senior architect but juniors writing production code. Compliance is rarely built in from day one, and code ownership is disputed at project end.
IRPR assigns a team of senior engineers (5+ years average) with expertise in security, scaling, and compliance. We give you a fixed price after a 1-week Roadmap phase, and you own every line of code from the first commit.
- Hourly billing with no cap
- Junior engineers writing core logic
- No built-in compliance testing
- Code ownership often contested
- Vague timeline with scope creep
- Minimal documentation and post-launch support
- Fixed price quoted in week 2
- Senior engineers only (5+ years)
- HIPAA, PCI-DSS, SOC 2 from day one
- Full IP transfer - source code in your repo
- Clear 8-12 week delivery schedule
- OpenAPI docs, Postman collection, CI/CD included
Our 4-Phase Process for Senior Backend API Development
From idea to production in 8-12 weeks. Each phase has a defined output and price lock.
We break every project into four phases: Discovery, Roadmap, Build, and Release. The first two phases are short (1 week each) and give us enough detail to fix the price and schedule.
During Build we work in 2-week sprints with daily standups and weekly demos. Release includes deployment, monitoring setup, and a 30-day warranty.
Every Senior Backend API Project Ships With These Deliverables
No hidden items. All artifacts are handed over at the end of the engagement.
We believe in full transparency. Everything listed below is included in the fixed price. There are no separate charges for documentation, testing, or deployment.
If you need additional integrations or features beyond the original scope, we handle them through a structured change request process with a clear cost impact.
- Source code in your private GitHub repository
- OpenAPI 3.0 specification (auto-generated)
- Postman collection with environment variables
- CI/CD pipeline on GitHub Actions or GitLab CI
- Unit tests with >90% coverage (Jest, pytest)
- Integration tests for all endpoints
- API monitoring dashboard in Datadog
- Sentry error tracking and alerting
- Deployment scripts for AWS, GCP, or Azure
- 30-day post-launch warranty and bug fixes
What we ship in this practice.
Payment Processing API for Fintech
Built a PCI-DSS Level 1 compliant payment API using Node.js, Stripe, and PostgreSQL. Reduced transaction failure rate by 40% and cut settlement time from 2 days to real-time.
Telehealth API for HIPAA Compliance
Developed a secure patient data exchange API with Twilio Video and Firebase. Handles 50,000+ video visits per month with end-to-end encryption and audit logging.
Multi-Tenant API for B2B SaaS
Created a RESTful API with role-based access control using Django REST Framework and PostgreSQL. Onboarded 200+ enterprise clients in the first quarter.
Order Management API for Ecommerce
Built synchronous order processing API with Shopify and Salesforce integrations using Go and Redis. Eliminated manual order entry, saving 12 hours per week for the operations team.
Real-Time Analytics API for Media Platform
Designed a WebSocket-based streaming analytics API with Node.js and Apache Kafka. Delivered sub-100ms latency for live viewer counts across 1 million concurrent users.
Inventory Sync API for Logistics
Implemented a GraphQL API that syncs inventory across 5 warehouses in real-time using AWS AppSync and DynamoDB. Reduced overselling incidents by 80%.
Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has at least 5 years of backend experience. We do not staff juniors or outsource core work. Our average team seniority is 7 years.
Fixed price, not hourly billing
You get a fixed price quote after the Roadmap phase (week 2). No hourly surcharges, no surprise invoices. The price covers the entire API build including documentation and deployment.
Full IP transfer and code ownership
From the first commit, code lives in your repository. You own everything we build. No license fees, no source code withholding. 100% of IRPR clients receive full IP rights.
Built-in compliance from day one
We embed HIPAA, PCI-DSS, and SOC 2 controls into the API design before a single line of code is written. This has saved our clients an average of $50,000 in retrofit costs.
8-12 week delivery guarantee
Our process is optimized for speed without quality trade-offs. 98% of our projects deliver on the date promised in the Roadmap. We guarantee it with a written timeline.
Dedicated project manager and weekly demos
A single point of contact manages priorities, meetings, and reporting. You see working code every week with a demo video and updated progress dashboard. No black boxes.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
