Senior Backend Development AgencyBackend Development
We build scalable backend systems with senior engineers only. Get a production-ready API in 8-12 weeks for a fixed price.
IRPR is a senior backend development agency staffed entirely with engineers who have 7+ years of experience. We build APIs, microservices, and cloud infrastructure using Node.js, Python, Go, and serverless frameworks like AWS Lambda.
Every project delivers a fully tested backend with CI/CD pipelines, monitoring, and documentation in 8-12 weeks. Pricing is fixed at $80K-$250K depending on scope. We comply with HIPAA, PCI-DSS, and SOC 2 standards.
CTOs who need to launch a SaaS product quickly, founders scaling an MVP to production, enterprises modernizing legacy backend systems, and VC-funded startups building their core platform hire IRPR for senior backend development.

Senior Backend Development Agency Metrics
Our senior engineers ship backend systems that perform under load.
IRPR has delivered over 200 backend projects across 50 countries. Average project timeline is 12 weeks from kickoff to production deploy.
We maintain 99.9% uptime across all client systems. Our team uses automated testing and CI/CD pipelines to catch issues before they reach production.
How IRPR Differs from Other Backend Agencies
Most backend development shops staff juniors and bill hourly. IRPR does the opposite.
Many agencies use a mix of junior and mid-level developers, leading to code quality issues and delayed timelines. They often charge by the hour, so scope creep inflates the final bill.
IRPR assigns only senior engineers with 7+ years of experience. Every project has a fixed price set during the Roadmap phase and a delivery date confirmed before any code is written.
- junior and mid-level developers
- hourly billing with no cap
- no written documentation
- unclear timelines
- no compliance expertise
- code ownership unclear
- senior engineers with 7+ years only
- fixed price from the start
- documentation and tests included
- 8-12 week guaranteed delivery
- HIPAA, PCI, SOC 2 ready
- you own 100% of the code
Our Senior Backend Development Process
We follow a four-phase process that starts with understanding your domain and ends with a production-ready backend.
Every engagement begins with a Discovery week where our engineers analyze your requirements, existing systems, and integration points. This feeds into a detailed Roadmap delivered in week two with a fixed price and timeline.
Development runs in 2-week sprints with demos every Friday. The final phase includes deployment, load testing, and a full handoff with documentation.
What Ships With Every Senior Backend Project
Every IRPR backend project comes with a standard set of deliverables that make your infrastructure production-ready.
These items are included in the fixed price - no hidden extras. Your team gets everything needed to maintain and extend the backend independently.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- AWS infrastructure provisioned via Terraform
- API documentation (OpenAPI/Swagger)
- Unit and integration tests (80%+ coverage)
- Sentry error tracking and logging setup
- CloudWatch or DataDog dashboards for monitoring
- Postman collection for all endpoints
- Deployment guide with runbooks
- Security audit report (OWASP top 10)

Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has 7+ years of experience. We don't staff juniors or offload work to low-cost regions. This means fewer bugs and faster delivery.
Fixed price from the start
You get a fixed price quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price covers the entire scope.
8-12 week delivery guarantee
We commit to a delivery date in the Roadmap. 98% of our projects ship on time. If we miss the date, we discount the final invoice by 10%.
100% code ownership
You own all source code, documentation, and infrastructure configurations. No licensing fees, no hidden IP claims. We transfer everything to your repos at the end.
Compliance-ready (HIPAA, PCI, SOC2)
Our team has built compliant backends for healthcare, fintech, and SaaS clients. We adhere to HIPAA Privacy Rule, PCI-DSS v4.0, and SOC 2 Type II controls.
Post-launch support and maintenance
After launch, we offer a monthly retainer for bug fixes, dependency updates, and minor features. Starting at $5K/month for 20 hours of senior engineer time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
