Custom Backend Development ServicesDevelopment Services
We build production-ready backends for SaaS platforms, fintech apps, and enterprise tools. Fixed price, 12 week delivery, senior engineers only.
IRPR provides custom backend development services for startups and mid-market companies that need a production-ready backend, not a prototype. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to build APIs, event-driven systems, and data pipelines that handle millions of requests per day.
Every project ships in 8-12 weeks at a fixed price between $80K and $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS, SOC 2), and other regulated industries. You get full code ownership, a CI/CD pipeline, and monitoring from day one.
Clients who hire us include CTOs at SaaS companies needing a scalable API backend, founders building fintech platforms who need PCI-compliant payment processing, product managers launching data-heavy marketplaces, and enterprise teams modernizing legacy systems with clean microservices.
Types of software we ship.
REST API Backend
Stateless REST APIs built with Express, FastAPI, or Gin. Includes OpenAPI docs, rate limiting, and JWT auth.
GraphQL Backend
GraphQL APIs with Apollo Server or Hasura. Optimized queries, real-time subscriptions, and schema stitching.

Why Custom Backend Development Services Matter for Your Business
Your backend is the engine that powers every customer interaction, data transaction, and system integration.
Off-the-shelf solutions like Firebase or Heroku work for prototypes, but they hit limits when you need custom business logic, strict compliance, or high throughput. With custom backend development services from IRPR, you get a backend purpose-built for your data model, your traffic patterns, and your compliance requirements.
We have shipped 200+ backends for companies in 50 countries. Our backends handle up to 100,000 requests per minute with 99.9% uptime. We use Node.js, Go, and Python because they deliver the best mix of performance and developer velocity for most use cases. Every project starts with a fixed price and a 12 week timeline.
How IRPR Delivers Custom Backend Development Services Differently
Most backend development agencies bill by the hour and change scope constantly. IRPR operates on fixed price and fixed timeline.
We start every engagement with a two-week Roadmap phase. In those first 14 days, we produce a detailed technical spec, a full architecture diagram, and a fixed price quote with no surprises. You know exactly what you get and exactly what it costs before we write a single line of production code.
Our engineers are senior only. The average team member has 10+ years of experience building distributed systems at companies like Amazon, Google, and Stripe. That means fewer bugs, faster decisions, and no time wasted teaching fundamentals. We ship code you can trust in production on day one.
- Hourly billing with no cap
- Scope creep every sprint
- Junior engineers learning on your dime
- No architecture review
- No compliance knowledge
- You own nothing — code stays on their servers
- Fixed price from Roadmap (week 2)
- Scope locked at contract signature
- Senior engineers only (10+ years avg)
- Architecture docs and decision log
- HIPAA, PCI-DSS, SOC 2 built in
- Full code ownership + CI/CD pipeline
Our Process for Custom Backend Development Services
Every project follows four phases. Each phase has a clear deliverable before we move to the next.
Phase 1 (Idea) takes one week. We review your requirements, user flows, and existing infrastructure. At the end of week 1, we have a prioritized feature list and a technical risk assessment.
Phase 2 (Roadmap) takes one week. We produce the architecture diagram, database schema, API contract, and a fixed price quote. Phase 3 (Product) is 8-12 weeks of development with weekly demos. Phase 4 (Release) includes load testing, security audit, CI/CD setup, and deployment to production.
What Ships With Every Custom Backend Development Project
Every deliverable includes production-grade infrastructure and full documentation. No hand-waving, no missing pieces.
We believe in shipping runnable, documented, observable code. That means every project includes a working CI/CD pipeline, monitoring dashboards, and an operations runbook. Your team can take over maintenance immediately without calling us.
All source code is in your private GitHub repo from day one. You own every line. We provide API documentation (OpenAPI 3.0), database ERD, deployment scripts, and a postman collection for testing.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- API docs in OpenAPI 3.0 format
- Database schema ERD (draw.io or LucidChart)
- Sentry error tracking + PagerDuty alerts
- CloudFormation or Terraform infrastructure as code
- Load test results from k6 or Artillery
- Security scan report from Snyk or Checkmarx
- Operations runbook for on-call engineers
- Postman collection for all API endpoints
What we ship in this practice.
Multi-Tenant API Backend for a B2B SaaS Platform

Our engineers average 10+ years of experience building distributed systems at Amazon, Google, and Stripe. You never pay for someone learning on the job.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant backends as standard. No add-on fees for compliance work. We reference the exact controls in your audit report.
Full code ownership
All source code, documentation, CI/CD scripts, and infrastructure as code belong to you from day one. No license fees, no vendor lock-in, no IP disputes.
Production observability out of the box
Every backend ships with Sentry error tracking, Datadog metrics, PagerDuty alerts, and a Grafana dashboard. Your team can monitor and debug in production immediately.
