Senior Custom Backend Development ConsultantsBackend Consultants
We build custom backend systems that scale to millions of users. Our senior consultants deliver production-ready APIs and microservices in 8-12 weeks.
IRPR provides senior custom backend development consultants who design and build production-grade systems using Node.js, Go, Python, PostgreSQL, Kafka, and Kubernetes. Each consultant has 10+ years of experience shipping software for startups and enterprises.
We deliver a working backend in 8-12 weeks with a fixed price from $80K to $250K. Every project includes SOC 2, HIPAA, PCI-DSS, or FERPA compliance as needed. You get a complete system with CI/CD, monitoring, and infrastructure as code.
Our clients are CTOs scaling SaaS platforms, product owners launching fintech or healthcare apps, non-technical founders building their first MVP, and enterprise IT teams modernizing legacy backends.
Types of software we ship.
RESTful API development
Build stateless APIs with Node.js or Go, connected to PostgreSQL and Redis. Includes OpenAPI specs and rate limiting.
Microservices architecture
Decompose monoliths into event-driven microservices using Kafka, Docker, and Kubernetes. Each service scales independently.
Real-time data pipelines
Process streaming data with Apache Kafka, Flink, and Redpanda. Deliver sub-100ms latency for analytics and alerts.
GraphQL backend
Implement a unified GraphQL layer with Apollo Federation. Reduces frontend bandwidth by 60% compared to REST.
Event-driven systems
Publish and consume domain events using NATS or RabbitMQ. Enables 10x faster feature releases through loose coupling.
Cloud infrastructure (AWS/GCP/Azure)
Provision autoscaling clusters with Terraform and Pulumi. Achieve 99.9% uptime with multi-region deployment.
Database design and optimization
Design normalized schemas, implement sharding and indexing. Queries run in <5ms using PostgreSQL or DynamoDB.
Backend for mobile apps
Build push notification services, file upload handlers, and auth using Firebase and AWS AppSync. Handles 10M+ concurrent users.
We build for every business type.

Why senior custom backend development consultants matter
Building a backend that handles real traffic requires deep experience.
Most generic developers cannot design for scale. They write monolithic code that works for 100 users but breaks at 10,000. IRPR's senior consultants architect systems using microservices, caching layers, and database sharding from day one.
We have shipped 200+ backend projects across 50+ countries. Each consultant averages 10 years of experience. Our systems maintain 99.9% uptime in production and process over 1 billion API calls per month.
The difference between generic developers and senior consultants
Not all developers can design systems that scale.
When you hire a generic freelance developer, you often get code that works today but breaks tomorrow. They skip automated testing, ignore scalability planning, and deliver on uncertain timelines.
IRPR's senior consultants have built systems for 200+ clients. We start every project with a clear architecture and fixed price, so you know exactly what you get and when.
- Builds monolithic code
- No automated tests
- No CI/CD
- Unclear API contracts
- No scalability plan
- Unpredictable timelines
- Designs microservices or modular monoliths
- Unit and integration tests >80% coverage
- CI/CD with GitHub Actions
- OpenAPI specification from day one
- Load testing and autoscaling setup
- Fixed 8-12 week timeline
Our backend development process
We follow a structured 4-phase approach that delivers production-ready code on time.
Each phase has clear deliverables and a fixed timeline. You see progress every two weeks.
IRPR uses this process for every project, regardless of industry or tech stack. It has been refined over 200+ projects.
What ships with every backend project
You get more than just code.
Every deliverable is documented and ready for your team to maintain. No black boxes, no hidden dependencies.
- Source code in your Git repo
- CI/CD pipeline on GitHub Actions
- Infrastructure as code (Terraform)
- API documentation (OpenAPI/Swagger)
- Postman collection for endpoints
- Load test results (k6)
- Monitoring dashboard (Datadog/Prometheus)
- Post-deployment support for 30 days

Why teams hire us.
Fixed price, no surprises
We give you a fixed quote after the roadmap phase (week 2). No hourly billing, no scope creep.
Senior engineers only
Every consultant has 10+ years experience. No junior developers, no offshore code mills.
8-12 week MVP delivery
From idea to production in 8-12 weeks. We ship a working MVP you can demo to investors.
Full code ownership
You own all source code, documentation, and infrastructure. No licensing fees, no vendor lock-in.
Compliance built in
We build HIPAA, SOC 2, PCI-DSS, and FERPA compliance into the architecture from day one.
Global team, async-first
Our team works across 50+ countries with 4-hour overlap with US time zones. You get daily progress.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
