Leading Custom Backend Development DevelopersCustom Backend
We build backend systems that handle millions of requests. Senior engineers, 8-12 week delivery, fixed pricing from $80K.
IRPR is a team of senior backend engineers who build custom backend systems for startups and enterprises. We use Node.js, Python, Go, PostgreSQL, MongoDB, Redis, and AWS to create APIs, microservices, and data pipelines that scale.
We ship production-ready backend code in 8-12 weeks for MVPs, with fixed pricing between $80K and $250K. Our systems comply with HIPAA, PCI-DSS, SOC 2, and FERPA. You own the source code from day one.
We work with CTOs who need a reliable backend team, product managers launching a new platform, founders building a SaaS MVP, and engineering leads scaling an existing system. Each client gets a dedicated senior engineer as a point of contact.

Why IRPR is the leading custom backend development team
We have shipped 200+ backend systems for clients in 50+ countries.
Every backend we build starts with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed quote and a clear timeline before any code is written. No surprises, no scope creep.
Our senior engineers have built backends for healthcare (HIPAA), fintech (PCI-DSS), and ecommerce (PCI). We use TypeScript, Node.js, Python, Go, PostgreSQL, Redis, and AWS. Every project includes automated testing, CI/CD, and monitoring.
How IRPR differs from other backend developers
Most agencies bill hourly and hand you incomplete code. We do the opposite.
We have seen projects fail because of unclear requirements, poor architecture, and no testing. IRPR fixes that with a structured process and senior-only engineers.
You get a fixed price, full code ownership, and a system that passes any compliance audit. We handle deployment, monitoring, and documentation.
- Hourly billing with no cap
- Junior devs learning on your project
- No architecture review
- Zero automated tests
- No CI/CD pipeline
- Code you cannot deploy yourself
- Fixed price from $80K
- Senior engineers only (10+ years)
- 2-week Roadmap with full spec
- 90%+ test coverage
- GitHub Actions CI/CD included
- Full code ownership + deployment guide
Our process for building your custom backend
From idea to production in 10-14 weeks.
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a sign-off gate.
No phase starts until the previous one is approved. This keeps the project on time and on budget.
What ships with every backend project
You get more than just code. Every deliverable is production-ready.
We include everything needed to run, maintain, and scale your backend. No hidden costs or missing pieces.
Your team can take over immediately because every file is documented and every API has a test.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automated tests
- Swagger/OpenAPI documentation for every endpoint
- PostgreSQL schema with indexes and migration scripts
- Redis caching layer with eviction policies
- Docker Compose setup for local development
- Sentry error tracking and Datadog performance monitoring
- Deployment guide with AWS CloudFormation templates
- Load test results showing 10K+ requests per second
- Security audit report (OWASP top 10 checks)
What we ship in this practice.
Multi-tenant SaaS API
Built a subscription billing backend for a B2B SaaS company. Handles 50K API calls per minute with sub-50ms latency. Tech stack: Node.js, PostgreSQL, Stripe, Redis. Reduced billing errors by 90%.
HIPAA-compliant patient data backend
Developed a FHIR-compliant API for a telehealth startup. Passed HIPAA audit on first submission. Tech stack: Python, FastAPI, PostgreSQL, AWS HealthLake. Reduced patient data retrieval time from 3 seconds to 200ms.
PCI-DSS payment processing backend
Built a tokenization service for an ecommerce platform. Processes 10K transactions per hour with zero PCI scope for the client. Tech stack: Go, Redis, AWS Lambda, Stripe. Saved $50K/year in compliance costs.
Real-time logistics tracking backend
Created a WebSocket-based tracking system for a logistics company. Handles 100K simultaneous connections with 99.9% uptime. Tech stack: Node.js, Socket.io, Redis, AWS ECS. Reduced driver wait times by 30%.
Ecommerce inventory management backend
Designed a real-time inventory sync API for a multi-warehouse retailer. Syncs stock levels across 10 warehouses in under 1 second. Tech stack: Node.js, PostgreSQL, RabbitMQ, AWS RDS. Cut stockouts by 60%.
EdTech gradebook backend
Built a FERPA-compliant gradebook API for a school district. Supports 50K students with role-based access for teachers, parents, and admins. Tech stack: Python, Django, PostgreSQL, AWS. Reduced grade entry time by 4 hours per week per teacher.
Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has 10+ years of experience. We do not hire juniors or outsource to offshore teams. You get a senior backend engineer as your daily contact.
Fixed price from the Roadmap phase
After the 2-week Roadmap, you get a fixed quote for the entire project. No hourly billing, no surprise invoices. If the scope changes, we re-quote before doing the work.
Full code ownership from day one
All source code is in your GitHub repository from the first commit. You own everything. No licensing fees, no lock-in. You can deploy with your own team immediately.
Built for compliance from the start
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture. Our systems pass audits on the first attempt. We include audit logs, encryption, and access controls by default.
Production-ready in 8-12 weeks
Most MVPs ship in 8-12 weeks. We use 2-week sprints with working demos at the end of each sprint. You see real code, not slides. We deploy to production and hand over the keys.
Post-launch support and maintenance
We offer a 3-month post-launch support package for $5K/month. Includes bug fixes, minor enhancements, and 24/7 monitoring. You can cancel anytime with no penalty.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
