Senior Backend Development CompanyBackend Development
We build scalable backend systems that handle millions of requests. Our senior engineers ship production-ready APIs in 8-12 weeks.
IRPR specializes in building production backend systems using Node.js, Go, Python, and TypeScript. We design RESTful and GraphQL APIs with PostgreSQL, Redis, and AWS infrastructure.
Each project ships as a fully tested codebase in your GitHub repo with CI/CD via GitHub Actions. Typical timeline is 8-12 weeks. Pricing ranges $80K-$250K fixed, depending on scope. We comply with HIPAA, PCI-DSS, and SOC 2.
CTOs at Series A startups who need to scale their platform. Engineering leaders at mid-market companies modernizing legacy systems. Product managers building SaaS MVPs with complex backend logic. Founders launching data-intensive applications.
Types of software we ship.
API Gateway Development
Build a unified API gateway using Kong or NGINX to route, rate-limit, and authenticate traffic across multiple microservices. Includes monitoring with Datadog.
Microservices Architecture
Decompose monoliths into containerized services running on Kubernetes. Each service gets its own database and CI/CD pipeline.
Event-Driven Systems
Implement event streaming with Apache Kafka or RabbitMQ for real-time data processing. Used for order fulfillment, notification queues, and analytics pipelines.
Real-Time Data Pipelines
Process streaming data with Apache Flink or AWS Kinesis. Transform and load into data warehouses like Snowflake for dashboards and ML.
CMS Backend APIs
Headless CMS backend with Strapi or Contentful API. Deliver content to web and mobile apps via GraphQL, with caching via Redis.
Payment Processing Integrations
Integrate Stripe, Braintree, or Adyen for subscription billing, invoicing, and multi-currency support. Includes PCI-compliant tokenization.
Authentication and Authorization
OAuth 2.0 and SAML-based SSO with Auth0 or custom JWT. Role-based access control (RBAC) for multi-tenant apps.
Webhook and Integration Platforms
Build a webhook receiver and dispatcher using Fastify and Bull queues. Map incoming events to downstream APIs like Slack, Salesforce, or HubSpot.
We build for every business type.
SaaS companies
Fintech companies
Healthcare companies
Ecommerce companies
Enterprise and other verticals
Why senior backend engineers matter
The backend is the engine of your application. A poorly designed backend leads to slow response times, costly rewrites, and security holes.
IRPR assigns only senior engineers with 10+ years of experience. Our teams have shipped backend systems for fintech, healthcare, and ecommerce companies handling millions of transactions.
We focus on scalability from day one. Every API endpoint is load-tested with artillery.io, databases are indexed for query performance, and infrastructure is deployed with Terraform for repeatability.
Generic dev shop vs IRPR
Not all backend development shops are the same. Here is how IRPR compares to a typical agency.
Generic shops often staff junior developers and bill by the hour. You end up with unclear costs, slow progress, and code that needs rewriting.
IRPR takes a different approach: all senior engineers, fixed pricing, and production-ready code from week one.
- Junior-heavy teams with minimal oversight
- Hourly billing with scope creep
- No automated testing or CI/CD
- No dedicated project manager
- Security reviews are optional
- Code ownership unclear
- All senior engineers with 10+ years experience
- Fixed price from week 2
- 100% test coverage with Cypress and Jest
- GitHub Actions CI/CD built-in
- OWASP security audit in final sprint
- Full IP and code ownership
Our backend development process
We follow a structured 12-week process to move from idea to production. Every phase has clear deliverables and approval points.
The process starts with a 2-week Roadmap where we define the architecture, data models, and a fixed-price contract. After approval, we move into three 3-week sprints.
Each sprint ends with a demo and deployment to a staging environment. You see working code every week.
What ships with your backend project
Every project comes with a complete set of deliverables that make your team self-sufficient from day one.
You receive everything needed to maintain and extend the system. No missing pieces, no vendor lock-in.
- Source code in your GitHub repo
- Automated CI/CD pipeline (GitHub Actions)
- Postman API collection with examples
- Swagger/OpenAPI documentation
- Database schema migration scripts
- Sentry error tracking integration
- AWS or GCP infrastructure as code (Terraform)
- Docker Compose for local development
- Load testing results (artillery.io)
- Security audit report (OWASP)
What we ship in this practice.
Multi-tenant SaaS backend for a B2B analytics platform
Built a shared-nothing architecture with PostgreSQL schemas per tenant. Reduced query latency by 40%. Tech: Node.js, Express, PostgreSQL, Redis, Docker.
Real-time payment processing engine for a fintech startup
Integrated Stripe Connect with custom webhook handling. Processed 10,000 transactions per minute during peak. Tech: Go, Kafka, CockroachDB, AWS.
HIPAA-compliant patient data API for a telemedicine app
Developed a FHIR-compliant API with end-to-end encryption. Passed HIPAA audit on first submission. Tech: Python, Django, PostgreSQL, HL7 FHIR.
Headless commerce backend for a global ecommerce brand
Built a custom API layer on top of Shopify. Handled 50,000 SKUs with multi-warehouse inventory sync. Tech: TypeScript, NestJS, GraphQL, Redis, AWS ECS.
Real-time collaboration backend for an edtech platform
WebSocket server with WebRTC signaling for live classes. Supported 500 concurrent participants with sub-200ms latency. Tech: Node.js, Socket.io, Redis, WebRTC.
IoT data pipeline for a manufacturing company
Ingested sensor data from 10,000 devices into Apache Kafka, processed with Flink, and stored in InfluxDB. Reduced downtime by 25%. Tech: Java, Kafka, Flink, InfluxDB, MQTT.
Why teams hire us.
All senior engineers, no juniors
Every developer on your project has 10+ years of experience building backend systems. We do not staff junior engineers to cut costs.
Fixed price, not hourly
We give you a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
98% on-time delivery
We track every sprint with weekly demos and a live Gantt chart. Over 200 projects shipped, 98% met the original deadline.
Production-ready code quality
100% test coverage with Cypress and Jest, automated CI/CD, and a security audit before launch. Your code is ready for production from day one.
Full ownership of code and IP
You own everything we build - source code, documentation, infrastructure configs. No licensing fees, no lock-in.
Compliance built in
We build with HIPAA, PCI-DSS, SOC 2, and FERPA requirements from the start. Our checklist includes encryption, audit logs, and access controls.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
