Why IRPR Is the Best Custom Backend Development Vendor For Your Project
We do not just write code. We design architectures that stay fast as your user base grows.
Every backend we build starts with a Roadmap phase where we define the data model, API contracts, and infrastructure. In week 2 you get a fixed-price quote and a timeline that we have met on 98% of our 200+ projects.
We use PostgreSQL for relational data, Redis for caching, and either AWS or GCP for hosting. Our microservices communicate over gRPC when latency matters, and REST for public APIs. We also add monitoring with Datadog and error tracking with Sentry.
What Sets the Best Custom Backend Development Vendor Apart
Most agencies hand you code and leave. IRPR ships a running system you own completely.
Generic dev shops often overpromise on timelines and underdeliver on reliability. They use hourly billing that rewards slowness and skip production hardening like load testing, autoscaling, and disaster recovery.
IRPR operates on fixed price from the Roadmap phase. Every backend includes CI/CD pipelines, automated tests, infrastructure as code (Terraform), and a 30-day post-launch support window.
- Hourly billing with unknown total cost
- No fixed timeline
- No monitoring or alerting
- Code delivered without tests
- No scalability plan
- Handoff without documentation
- Fixed price agreed in week 2
- 8-12 week delivery window
- Datadog and Sentry pre-configured
- 90%+ test coverage
- Auto-scaling via Kubernetes or AWS ECS
- Full architecture diagram and runbooks
How We Deliver Your Custom Backend
Four phases that take you from idea to production backend in 8 to 12 weeks.
We start with a 1-week Discovery call to understand your data, users, and scaling needs. Then the Roadmap phase produces a detailed spec and a fixed price. Build phase is 6-10 weeks of sprints with demos every two weeks. Release phase includes load testing, security audit, and deployment to production.
Throughout the project you have direct access to the senior engineers building your system. No account managers. No offshore teams.
What Ships With Every Custom Backend
Everything you need to run a production system from day one.
We do not just send you a ZIP file. Every backend includes infrastructure code, documentation, and monitoring out of the box.
Your team can deploy, debug, and scale the system without calling us. Code is in your GitHub repo from the first commit.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerfile and docker-compose for local dev
- Terraform scripts for AWS or GCP
- Postman collection for all API endpoints
- Sentry error tracking configured
- Datadog dashboards for latency and errors
- Load test results (Locust) included in report
What we ship in this practice.
SaaS multi-tenant API for B2B analytics
Built a multi-tenant REST API with tenant isolation via separate schema per customer. Reduced data breach risk and cut onboarding time from 3 weeks to 2 days. Tech stack: Node.js, PostgreSQL, Redis, AWS ECS.
Real-time order tracking backend for a logistics startup
Developed a WebSocket-based order tracking service that pushed GPS updates every 5 seconds. Handled 10,000 concurrent drivers with 200ms latency. Tech stack: Go, RabbitMQ, TimescaleDB.
HIPAA-compliant patient data API for a telemedicine company
Designed a FHIR-compliant backend with AES-256 encryption at rest and TLS in transit. Passed HIPAA audit in month 1. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS.
Payment processing microservice for a fintech startup
Built a PCI-DSS compliant payment orchestration backend that connected Stripe, Braintree, and PayPal under one API. Reduced failed transactions by 35%. Tech stack: Node.js, Kafka, MongoDB, Docker.
Ecommerce checkout backend for a DTC brand
Replaced Shopify checkout with a custom Node.js service that handled 1,200 orders/minute on Black Friday. Saved 3% in transaction fees. Tech stack: Node.js, Redis queue, Stripe API, Cloudflare.
Data pipeline for a real estate analytics platform
Built an ETL pipeline that ingests MLS data from 50+ sources into a unified schema. Reduced data refresh time from 12 hours to 20 minutes. Tech stack: Python, Apache Airflow, Snowflake, dbt.
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 cost before we write a line of code.
Senior engineers only
All engineers have 10+ years of experience. No juniors, no interns. Every developer on your project has shipped at least 5 production backends.
Production-ready from week 1
We deploy to a staging environment in the first week. CI/CD, load testing, and monitoring are configured before the main build starts. You see real progress early.
Full code ownership
You own every line of code from the first commit. No license fees, no proprietary frameworks. Your backend runs entirely on your infrastructure.
Compliance built-in
We build backends that pass HIPAA, SOC 2, and PCI-DSS audits. Encryption, logging, and access controls are part of the architecture, not an afterthought.
30-day post-launch support
After release we monitor the system for 30 days, fix any bugs, and help your team take over. No surprise handoff problems.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
