Expert Backend Development AgencyBackend Development
We build the backend systems that power your product. 8-12 week MVPs with Node.js, Python, or Go.
IRPR is an expert backend development agency that builds server-side systems for web, mobile, and AI products. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to create APIs, microservices, and data pipelines that scale.
Every project ships with source code, CI/CD on GitHub Actions, error tracking via Sentry, and monitoring on Datadog. Typical delivery is 8-12 weeks for an MVP, with fixed pricing from $80K to $250K. We comply with HIPAA, PCI-DSS, and SOC 2 as needed.
Companies hire us when they need senior backend engineers they can trust: CTOs scaling a SaaS, founders building a fintech MVP, healthcare startups requiring HIPAA compliance, and ecommerce brands needing PCI-compliant payments.

Why choose an expert backend development agency
You need engineers who have shipped production systems at scale. Here are the numbers that prove IRPR delivers.
IRPR has completed 200+ backend projects for clients in 50+ countries. Our on-time delivery rate is 98%, and we maintain a 99.9% uptime SLA for every production system we deploy.
Typical backend MVPs ship in 8-12 weeks at a fixed price of $80K-$250K. We use Node.js, Python, Go, and Rust depending on your latency and concurrency needs. Every project includes a full CI/CD pipeline and monitoring stack.
How IRPR differs from other backend agencies
Most dev shops talk about quality. IRPR delivers fixed price, senior engineers, and complete ownership.
Generic agencies often assign junior devs who learn on your dime. They also charge by the hour, which creates incentive to stretch timelines. IRPR only hires senior engineers with 8+ years experience and uses a fixed-price model starting in the Roadmap phase.
You get source code ownership, a deployed system with monitoring, and a 1-year warranty on production issues. No black boxes. No vendor lock-in.
- Junior developers with 2 years experience
- Hourly billing with no cap
- No monitoring or error tracking by default
- Code owned by agency until full payment
- No compliance expertise (HIPAA, PCI)
- Average project timeline 4-6 months
- Senior engineers with 8+ years experience
- Fixed price from Roadmap phase
- Sentry, Datadog, and PagerDuty included
- Full source code ownership from day one
- HIPAA, PCI-DSS, SOC 2 compliant builds
- MVP delivery in 8-12 weeks
Our backend development process
We follow a four-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and no surprises.
Idea: In week 1 we align on goals, choose your tech stack (Node.js, Python, Go), and define the API contract. Roadmap: By week 2 you get a fixed price quote and a detailed build plan with milestones.
Product: Build sprint starts. We code and deploy incremental features every 2 weeks. Release: Final QA, performance testing, and handover. You own the code, the repo, and the monitoring.
What ships with every backend project
You get more than just code. Every project includes a fully operational production system with monitoring, logging, and alerts.
We believe in shipping production-ready systems, not prototypes. That's why every IRPR backend project comes with a complete DevOps stack out of the box.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and performance monitoring
- Datadog dashboards for CPU, memory, and request latency
- PagerDuty alerts for critical issues
- Docker containers and Docker Compose for local dev
- API documentation generated from OpenAPI schema
- Database migration scripts (PostgreSQL, Redis)
- Load testing results from k6 or Locust
- 1-year warranty on production issues
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every backend project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
All IRPR engineers have 8+ years of backend experience. We do not hire juniors. You get a lead engineer and a dedicated QA on every project.
Full code ownership
You own all source code from day one. We create a private GitHub repo under your account. No licensing fees, no lock-in.
Production-grade monitoring by default
Every project includes Sentry error tracking, Datadog dashboards, and PagerDuty alerts. You see your system health from day one of deployment.
Compliance built in
We have built HIPAA-compliant backends for 12 healthcare clients and PCI-DSS systems for 8 fintech companies. SOC 2 audits passed on all SaaS projects.
Fast start, fast delivery
We kick off within 1-2 weeks of signing. Backend MVPs ship in 8-12 weeks. A dedicated team starts building immediately after the Roadmap phase.
