Why leading companies choose IRPR for backend app development
Our backend services deliver measurable results. Every project ships with guaranteed compliance, performance, and ownership.
We have shipped 200+ products across 50+ countries, with 98% on-time delivery. Our senior engineers average 12+ years of experience in backend architecture.
Every backend we build achieves 99.9% uptime with automated monitoring, error tracking via Sentry, and performance benchmarks.
How we differ from generic backend agencies
Most agencies promise custom work but deliver cookie-cutter code with no compliance or post-launch support.
Generic shops often bill hourly, miss deadlines, and hand off code with no documentation or tests. You are left with technical debt and no warranty.
IRPR delivers fixed price, full documentation, 1-year warranty, and built-in compliance from day one.
- hourly billing that blows budgets
- vague timelines that slip weeks
- no compliance expertise (HIPAA, PCI-DSS)
- handoff with zero documentation
- no post-launch support
- unstable code with no tests
- fixed price from week 2 of the project
- 8-12 week delivery with 98% on-time rate
- HIPAA, PCI-DSS, SOC2 built into architecture
- full Swagger docs, unit tests (80%+ coverage)
- 1-year warranty on all code
- CI/CD pipeline with Sentry and Datadog monitoring
Our backend development process
We use a proven 4-phase approach that guarantees clarity, speed, and quality.
Each phase has a fixed duration and delivers a concrete artifact. You review and approve at every step.
From roadmap to production, you always know what is coming next.
What ships with every backend project
Every project includes these concrete deliverables.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Sentry error tracking with alerts
- API documentation (Swagger/OpenAPI)
- Unit and integration tests (minimum 80% coverage)
- Infrastructure as code using Terraform or Pulumi
- Security audit results (OWASP Top 10)
- Performance benchmark report
- Admin dashboard with metrics and logs
What we ship in this practice.
SaaS booking platform backend
Built a Node.js and PostgreSQL API that handles 5,000 bookings per hour. Integrated Stripe for payments and Twilio for SMS confirmations. Average booking time dropped by 40%.
Healthcare data pipeline
Designed a Python Flask backend that ingests 10,000 patient records per hour from legacy EHRs. HIPAA-compliant storage on AWS with encryption at rest and in transit.
Fintech payment gateway
Created a Go-based PCI-DSS Level 1 compliant backend that processes $5M in transactions per month. Integrated with multiple acquiring banks via ISO 8583.
Real-time chat system
Built a Node.js and WebSocket backend with Redis pub/sub to support 100,000 concurrent users. Used for live customer support across 3 countries.
E-commerce backend with headless CMS
Developed a Django + GraphQL backend that powers a multi-vendor marketplace. Integrated with Stripe Connect and Shopify APIs. Reduced cart abandonment by 25%.
IoT data lake for manufacturing
Deployed an AWS Kinesis and Lambda pipeline that ingests 1 TB of sensor data per day. Data stored in S3 and queried via Athena. Helped reduce machine downtime by 30%.
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 budget from day one.
Senior engineers only
We hire the top 1% of developers. Our team averages 12+ years of backend experience. You never get junior developers learning on your dime.
Full compliance built-in
HIPAA, PCI-DSS, SOC 2, FERPA — we build compliance into the architecture from week 1. No costly retrofits. Over 60% of our projects are in regulated industries.
8-12 week delivery
We ship MVPs in 8-12 weeks with 98% on-time delivery. Our sprint-based process keeps you informed and in control. No endless timelines.
1-year post-launch warranty
If a bug surfaces within the first year, we fix it at no charge. Most firms hand off and disappear. We stay on call with a 4-hour SLA.
You own 100% of the code
All source code, documentation, and IP transfer to you upon payment. No licensing fees, no locked-in vendors. You can take it anywhere.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
