Professional Custom Backend DevelopmentConsultants
We build backend systems that scale from day one. Fixed price, no hourly billing, and a senior engineer assigned to your project.
IRPR is a software development studio that builds custom backend systems for businesses that need reliability and speed. We use Node.js, Go, Python, PostgreSQL, Redis, and cloud providers like AWS, GCP, and Azure to create architectures that handle millions of requests.
Every project ships with a fully documented API, CI/CD pipeline, monitoring setup, and database schema. Typical MVPs take 8 to 12 weeks and cost between $80,000 and $250,000. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards where required.
We work with CTOs who need a backend built from scratch, startup founders launching a SaaS product that needs a scalable data layer, and product managers who inherited a legacy monolith that needs to be refactored into microservices. These buyers come to IRPR because they need certainty on timeline and price.
Types of software we ship.
REST API development
Build stateless, versioned REST APIs with Express.js or Go gin. Includes JWT auth, rate limiting, and Swagger docs.
GraphQL backend
GraphQL resolvers and schemas using Apollo Server or Hasura. Real-time subscriptions and granular data fetching.
Microservices architecture
Decompose monoliths into isolated services with message queues (RabbitMQ, Kafka) and container orchestration (Kubernetes).
Real-time backend systems
WebSocket servers with Socket.io or raw WS. Used for live dashboards, chat apps, and collaborative editing tools.
Serverless backend
Lambda functions, API Gateway, and DynamoDB on AWS. Auto-scales from zero to peak traffic without provisioning servers.
Database design and optimization
Schema design for PostgreSQL, MongoDB, or DynamoDB. Includes indexing, partitioning, and query optimization for speed.
Third-party API integration backend
Integrate with Stripe, Salesforce, HubSpot, Plaid, or Twilio. Handle webhooks, rate limits, and data mapping.
Authentication and authorization systems
OAuth 2.0, SAML, and custom JWT implementations. Role-based access control with audit logging for compliance.
We build for every business type.
Healthcare
Fintech
SaaS
Ecommerce
Real Estate
Why professional custom backend development consultants matter
Your frontend is only as reliable as the backend it talks to.
A poorly designed backend causes slow page loads, data loss, and downtime that loses customers. IRPR designs backend systems that handle traffic spikes, maintain data integrity, and stay available 99.9% of the time. We use proven patterns like circuit breakers, retry logic, and idempotency to prevent failures.
Every backend we ship includes a monitoring dashboard with Sentry, Datadog, or Prometheus so you see errors and performance in real time. We set up alarms for p99 latency, error rates, and database connection pool usage. Your operations team gets alerts before users notice anything.
Generic dev shop vs IRPR
Most dev shops bill hourly and disappear after launch. IRPR is different.
We have seen projects that started with a $30/hour offshore team and ended up costing $200,000 with no documentation and a database that cannot scale. That is the norm, not the exception. Generic shops hire junior developers and throw them at the problem.
IRPR assigns a senior engineer to your project from day one. Every line of code is reviewed. Every API endpoint has a test. You get a fixed price in week 2 of the Roadmap phase, not a vague estimate that balloons.
- Hourly billing with no cap
- Junior or mid-level developers
- No testing or poor test coverage
- No monitoring or alerting
- No documentation or handover
- Code is abandoned after launch
- Fixed price after Roadmap phase
- Senior engineer assigned to each project
- 100% test coverage for critical paths
- Sentry, Datadog, or Prometheus monitoring
- Full API docs and runbook
- Post-launch support and SLAs
How we build your custom backend
Four phases, no surprises, full transparency.
IRPR works in a structured process that starts with understanding your data model and API requirements. We do not write a single line of code until you approve the architecture. Every phase ends with a deliverable you can review.
The process takes 8 to 12 weeks for an MVP. We schedule weekly demos so you see progress and give feedback. If something needs to change, we change it early when it costs nothing.
What ships with every backend project
You get more than just code. Every project includes these deliverables.
When IRPR builds your backend, you are not left with a black box. We hand over everything you need to run, maintain, and extend the system. No hidden dependencies. No missing passwords.
Our delivery checklist ensures nothing is forgotten. Your team can take over immediately or we can continue to support you post-launch. Either way, you have full control.
- Source code in your Git repository (GitHub or GitLab)
- CI/CD pipeline with GitHub Actions or CircleCI
- Docker images for every service
- Database schema migration scripts
- Postman collection or OpenAPI spec for all endpoints
- Sentry error tracking integrated
- Datadog or Prometheus monitoring dashboard
- Runbook with deployment and recovery steps
- API documentation hosted on ReadMe or GitBook
- Slack or PagerDuty alerting for production issues
What we ship in this practice.
Payment processing backend for Fintech SaaS
Built a PCI-DSS compliant backend that handles 10,000 transactions per minute. Uses Node.js, PostgreSQL, and Stripe Connect. Reduced manual reconciliation from 20 hours to 2 hours per week.
EHR data exchange platform for healthcare
Created a FHIR-compliant API that connects 3 legacy hospital systems. Uses Go, HL7 v2, and AWS HealthLake. Cut patient record retrieval from 4 minutes to 5 seconds.
Multi-tenant CRM backend for a startup
Built a microservices backend with 12 services for account, contact, deal, and activity management. Uses Python, PostgreSQL, and Redis. Scaled from 50 to 5,000 customers in 8 months.
Real-time inventory system for ecommerce
Designed a real-time inventory sync that updates stock across 4 warehouses and 2 online stores. Uses Go, RabbitMQ, and WebSockets. Eliminated overselling incidents entirely.
MLS data aggregation pipeline for real estate
Built a daily data pipeline that ingests listings from 12 MLS providers, deduplicates them, and serves via a GraphQL API. Uses Python, Airflow, and Postgres. Reduced data latency from 24 hours to 15 minutes.
Student management system for edtech
Developed a FERPA-compliant backend for a K-12 platform with 50,000 active users. Uses Node.js, MongoDB, and Redis. Handles 2,000 concurrent logins during peak hours.
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. You know the cost before we write code.
Senior engineers only
We do not hire juniors. Every engineer at IRPR has at least 8 years of experience and has built production systems serving millions of users. You get someone who has seen every mistake.
8 to 12 week MVPs
We ship a working backend in 8 to 12 weeks. That includes authentication, API endpoints, database schema, CI/CD, and monitoring. Most agencies take 6 months for the same scope.
Full ownership of code and infrastructure
You own the source code, Docker images, CI/CD pipeline, and cloud accounts from day one. There is no vendor lock-in. You can walk away tomorrow and run it yourself.
Compliance built in
We have built HIPAA-compliant systems for healthcare, PCI-DSS for fintech, and SOC 2 for SaaS. We include encryption, audit logs, and access controls in the scope.
Post-launch support with SLAs
After launch, we offer maintenance with guaranteed response times. Critical bug fixes within 4 hours. Minor issues within 24 hours. You are never alone after go-live.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
