Premium Backend API Development AgencyBackend API Development
We build backend APIs that scale to 10M+ requests. Senior engineers ship in 8-12 weeks with fixed pricing.
We design and build premium backend APIs using Node.js, Python, Go, and serverless frameworks like AWS Lambda. Each API includes authentication, rate limiting, caching, and database optimization with PostgreSQL or Redis.
Every engagement ships with auto-scalable infrastructure, CI/CD on GitHub Actions, and Sentry monitoring. Typical timeline is 8-12 weeks with fixed pricing from $80K to $250K. We work under HIPAA, PCI-DSS, and SOC 2 compliance requirements.
CTOs scaling their platform hire us to replace legacy APIs. Startup founders need an MVP backend that can handle 10K concurrent users. Enterprise teams require multi-tenant architecture with granular access control. SaaS companies need an API that integrates with Stripe, HubSpot, and Salesforce out of the box.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with OpenAPI specs. Use Express, FastAPI, or Gin for high throughput. Includes versioning and comprehensive testing.
GraphQL API Development
Implement GraphQL gateways with Apollo or Hasura. Resolve nested queries efficiently using DataLoader and caching layers.
Microservices Architecture
Decompose monoliths into independent microservices. Use Docker, Kubernetes, and RabbitMQ or Kafka for event-driven communication.
Real-time API (WebSocket)
Build real-time APIs with WebSocket or Server-Sent Events. Power live dashboards, notifications, and collaborative features using Socket.io or WebSocket API.
Internal API Gateway
Create a unified gateway for microservices with Kong or AWS API Gateway. Handle routing, authentication, rate limiting, and logging in one layer.
Third-party API Integration
Integrate with Stripe, Salesforce, HubSpot, Twilio, and more. Build abstraction layers that allow swapping providers without code changes.
API Versioning & Migration
Manage API versioning with URL or header strategies. Migrate V1 to V2 without breaking existing clients. Deprecation notices and sunset timelines included.
API Security Auditing
Audit endpoints for OWASP Top 10 vulnerabilities. Implement JWT, OAuth 2.0, API keys, and role-based access control. Penetration test reports delivered.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Logistics
Our track record building premium backend APIs
Backed by real numbers from 200+ shipped products across 50+ countries.
Every API we build is designed for scale from day one. We use load testing with k6 or Artillery to verify throughput targets. On average, our APIs handle 5,000 requests per second with p99 latency under 50ms.
We ship with complete documentation (OpenAPI/Swagger), automated tests, and deployment playbooks. Clients retain full code ownership and can deploy anywhere - AWS, GCP, Azure, or on-premise.
The difference between generic dev shops and IRPR
Not all agencies build premium backend APIs with the same quality and transparency.
Generic dev shops often assign junior engineers and charge by the hour. Budgets bloat, timelines slip, and code quality suffers. They rarely deliver CI/CD pipelines or monitoring out of the box.
IRPR assigns senior engineers only, uses fixed pricing from week 2, and ships a production-ready API with automated deployments, error tracking (Sentry), and performance monitoring (Datadog).
- No fixed price - hourly billing only
- Junior engineers on your project
- No compliance experience (HIPAA/PCI)
- No CI/CD pipeline provided
- No monitoring or alerting setup
- Code ownership unclear
- Fixed price locked in after 2-week Roadmap
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 compliant by default
- CI/CD on GitHub Actions included
- Sentry error tracking + PagerDuty alerts
- Full code ownership transferred to you
Our 4-step process for premium backend API development
From idea to production in 8-12 weeks with clear milestones.
Each phase delivers a working artifact. You see progress every week, never a black box. The process is designed to de-risk your investment.
We use Agile sprints with daily standups and weekly demos. Changes are welcome during the build phase without cost overruns because we fix the scope in week 2.
What ships with every premium backend API
You get a production-ready API, not just code in a repo.
Every engagement includes everything you need to run in production from day one. No hidden add-ons.
Our checklist ensures your team can deploy, debug, and scale independently after handoff.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions
- PostgreSQL schema with migrations
- GraphQL schema with resolver code (if applicable)
- REST endpoints with OpenAPI 3.0 documentation
- Authentication system (JWT + OAuth 2.0)
- Unit and integration tests (coverage > 90%)
- Sentry error tracking
- Datadog performance monitoring dashboard
- Infrastructure as Code (Terraform or Pulumi)
What we ship in this practice.
Real-time Payment Processing API
Built for a fintech startup handling 15K transactions/hour. Uses Node.js, Express, Stripe Connect, and PostgreSQL. Achieved 99.99% uptime and reduced payment settlement from 3 days to 24 hours.
Healthcare Data Exchange API
Connected two hospital systems using FHIR standard on AWS Lambda with Python. Compliant with HIPAA and SOC 2. Cut data transfer time from 45 minutes to 3 seconds per record.
Ecommerce Product Catalog API
Serves 50K SKUs for an online marketplace using GraphQL (Apollo) backed by PostgreSQL and Elasticsearch. Handles 10K concurrent search requests with p99 latency under 200ms.
Multi-tenant SaaS Backend API
Architected with Go microservices on Kubernetes. Each tenant gets isolated database schemas and rate limits. Supports 500+ tenants without performance degradation.
Fleet Tracking API
Processes GPS data from 5,000 vehicles every 10 seconds using Node.js, MQTT, and MongoDB. Provides real-time location and geofence alerts. Reduced fuel cost by 8% through route optimization.
Social Media Feed API
Delivers personalized feeds to 2M users using Python (FastAPI), Kafka, and Cassandra. Achieves sub-second feed generation through pre-computation and caching.
Why teams hire us.
Fixed price from week 2
We lock your budget after a 2-week Roadmap phase. No hourly billing, no overtime charges. Our average premium backend API costs between $80K and $250K.
Senior engineers only
Every engineer has 10+ years building APIs. We never outsource or use junior devs. Your project gets a dedicated tech lead with architecture experience.
8-12 week delivery
We deliver a production-ready API in 8-12 weeks, not months. Our process uses parallel workstreams and automated testing to speed up development.
Full code ownership
You own every line of code. We transfer the repo, documentation, and all deployment artifacts at the end. No license fees or ongoing royalties.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Encryption at rest and in transit, audit logs, and role-based access are included.
We use modern stack
Node.js, Python, Go, PostgreSQL, Redis, Kubernetes, AWS Lambda, and GraphQL. We pick the right tools for your scale. No legacy tech unless you need it.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
