Expert Backend App Development ConsultantsBackend App
We build APIs, microservices, and databases that scale. Get a fixed-price plan in week 2, code in your repo by week 12.
IRPR's expert backend app development consultants design and build server-side systems using Node.js, Python, Go, and Rust. We handle API architecture, database design, cloud infrastructure, and system integrations for applications that handle millions of requests per day.
Every project ships with source code in your repo, CI/CD pipelines on GitHub Actions, Sentry error monitoring, and full documentation. Typical backend consulting engagements run 8-12 weeks and cost between $80,000 and $250,000. We build for HIPAA, PCI-DSS, and SOC 2 compliance out of the box.
Founders needing a scalable MVP backend, CTOs migrating from monoliths to microservices, product managers adding real-time features, and enterprise teams modernizing legacy APIs all hire IRPR for expert backend app development consulting.

Why Expert Backend Consultants Matter
Backend systems are the core of any application. A strong foundation prevents costly rework.
IRPR's expert backend app development consultants have shipped over 200 production backends. Each system is designed for 99.9% uptime and handles an average of 1 million API calls per day per client.
We use the same architecture patterns for enterprise clients and startups. This means your backend is production-ready from day one. No technical debt, no surprise scalability issues.
Generic Dev Shop vs IRPR Backend Consultants
Most dev shops assign junior devs to your backend. We don't.
A typical agency outsources backend work to the cheapest developers. They use hourly billing, ignore architecture, and deliver code with no monitoring or docs. You pay more and get less.
IRPR assigns senior engineers with 10+ years of experience. Every project starts with a fixed price, a detailed architecture blueprint, and a clear timeline. We ship a production-ready backend with monitoring and full ownership.
- Hourly billing with no cap
- Junior or offshore developers
- No architecture review upfront
- No monitoring or alerting setup
- Code owned by agency
- No load testing
- Fixed price from week 2
- Senior engineers only (10+ years)
- Architecture blueprint delivered
- Automated CI/CD with GitHub Actions
- Full IP ownership
- Load testing with k6 and 100x traffic
Our Backend Consulting Process
We follow a structured 4-phase approach to deliver your backend on time and on budget.
Every engagement follows the same proven process. It starts with a kickoff call and ends with a production-ready backend in your repo. Each phase has clear deliverables and milestones.
What Ships With Every Backend Project
Every deliverable is production-ready. You get more than just code.
We don't just hand over a zip file. Every backend consulting engagement includes a full set of tools and documentation to run, monitor, and scale your system.
- Source code in your private GitHub repo
- Complete API documentation (Swagger/OpenAPI)
- CI/CD pipeline on GitHub Actions
- Sentry error and performance monitoring
- Database migration scripts with version control
- Load test results with k6 (100x expected traffic)
- Security audit report (OWASP top 10)
- Postman collection for all endpoints
- Deployment guide with Terraform or Pulumi scripts
- 1-hour walkthrough and knowledge transfer session

Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant backends with encryption, audit logs, and access controls. Compliance is not an afterthought.
Production Monitoring Included
Every backend ships with Sentry, Datadog, and PagerDuty alerts. You get real-time error tracking, performance metrics, and 24/7 alerting.
