Why choose a top custom backend development firm
We deliver production-ready backend systems that handle millions of requests from day one.
Building a backend that scales requires more than just code. It requires architecture decisions around database sharding, caching, async processing, and API design. IRPR's engineers have shipped over 200 production backends across 50 countries.
We use Node.js, Go, and Python for compute, with PostgreSQL, Redis, and Elasticsearch for data. Every system includes CI/CD pipelines, automated tests, and monitoring with Datadog and Sentry. You get a backend that does not break under load.
The difference between IRPR and a generic dev agency
Most agencies over-promise and under-deliver. IRPR builds backends that are production-ready and compliant.
Generic agencies often start coding without a clear roadmap. They use hourly billing, skip compliance, and hand you code without tests or documentation. You end up with costly rework.
IRPR starts with a fixed-price Roadmap in week 2. We build with compliance (HIPAA, PCI, SOC2) built in. Every delivery includes source code, CI/CD, tests, and monitoring. You own everything.
- Vague specs that change during development
- Hourly billing that blows budgets
- No compliance experience
- Code delivered without tests or docs
- No monitoring or error tracking
- You do not own the full IP
- Fixed price locked after Roadmap phase
- 8-12 week delivery with clear milestones
- HIPAA, PCI-DSS, SOC 2 built by default
- 100% test coverage on critical paths
- Datadog monitoring and Sentry error tracking
- Full source code ownership
Our backend development process in 4 phases
We follow a structured 12-week process that eliminates guesswork and delivers production code.
Every project starts with a 1-week Discovery call. We map your requirements, identify risk areas, and propose a tech stack. Then we write a fixed-price Roadmap that locks scope and cost.
After Roadmap approval, we build in 2-week sprints. You see working code every 14 days. Final week is for staging deployment, load testing, and handover.
What ships with every backend project
You get a complete production system, not just code. Every deliverable is designed for long-term maintenance.
IRPR does not hand over a zip file and walk away. We deliver a fully operational backend that your team can run and extend. All artifacts are in your repository from day one.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab
- Dockerized development and production environment
- API documentation generated via Swagger / OpenAPI
- Load testing report with k6 or Artillery
- Security audit summary covering OWASP top 10
- Monitoring dashboard on Datadog or Grafana
- Error tracking with Sentry
- Database migration scripts with version control
- Deployment runbook for production launch
What we ship in this practice.
Real-time payment processing backend
Built a PCI-compliant payment backend for a fintech startup. Handles 10,000 transactions per minute using Node.js, Kafka, and Stripe. Reduced manual reconciliation from 4 hours to zero.
Healthcare patient data API
Developed a FHIR-compliant API for a telemedicine platform. Uses Go and PostgreSQL with HIPAA-compliant encryption. Serves 500,000 patient records daily with 99.9% uptime.
Ecommerce order management backend
Built a microservices backend for a multi-brand retailer. Uses Python, Redis, and Shopify integration. Reduced order processing time from 3 minutes to 8 seconds.
SaaS multi-tenant backend
Designed a multi-tenant backend for a B2B analytics platform. Uses Ruby on Rails, AWS RDS, and Stripe. Onboards new customers in 5 minutes with automated provisioning.
Video streaming backend
Created a backend for a video-on-demand service. Uses Node.js, S3, and CloudFront with dynamic bitrate packaging. Supports 1 million concurrent viewers with sub-second latency.
IoT data ingestion pipeline
Built a backend for a manufacturing sensor network. Uses Go, MQTT, and InfluxDB. Ingests 50,000 data points per second and triggers real-time alerts on anomalies.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Engineer-led projects
Senior engineers run every project, not account managers. You talk directly to the people writing your code.
Compliance built in
HIPAA, PCI-DSS, and SOC 2 controls are part of our default stack. We do not add compliance as an afterthought.
You own the code
Full source code, documentation, and infrastructure config are in your repository. No licensing fees, no vendor lock-in.
Async-first communication
We work across time zones with daily async updates. Overlap hours with your team are scheduled as needed.
Post-launch support
We offer 30 days of post-launch support and a 99.9% uptime SLA. You can extend support on a monthly basis.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
