Best Custom Backend Development FirmBackend Development
We build high-performance APIs and server systems for startups and enterprises. 200+ products shipped, fixed pricing, and no scope creep.
IRPR engineers custom backend systems for web, mobile, and SaaS products. We use Node.js, TypeScript, Go, Python, and PostgreSQL to build scalable APIs and microservices.
Every project ships in 8-12 weeks with a fixed price starting at $80K. We handle compliance like HIPAA, PCI-DSS, and SOC 2, and deliver full source code, CI/CD pipelines, and cloud infrastructure.
CTOs needing a reliable backend team, founders building MVPs with complex server logic, enterprise IT teams migrating legacy systems, and product managers adding API layers hire us.
Types of software we ship.

What a custom backend delivers
Every backend we build ships with production-ready architecture, documentation, and monitoring.
IRPR has shipped 200+ backend systems for clients across 50+ countries. Our average project completes in 12 weeks, with 98% delivered on time. Each system includes automated tests, CI/CD pipelines, and cloud deployment scripts.
We start with a detailed architecture document during the Roadmap phase. Clients review the schema design, API contracts, and infrastructure choices before we write a single line of production code. This eliminates surprises and rework.
How IRPR beats generic dev shops
Most backend development firms hide scope creep and hourly overruns. We don't.
Generic shops often charge hourly and push deadlines. They deliver incomplete documentation and disappear after launch. IRPR operates differently: fixed price, full transparency, and long-term support.
We assign a dedicated engineering lead who communicates directly with your team. You get daily standup summaries, a shared Jira board, and a clear feature completion report every week.
- Hourly billing with no cap
- Unclear project timeline
- No compliance certifications
- Code hosted on personal accounts
- No automated testing
- Limited cloud architecture knowledge
- Fixed price from $80K
- 8-12 week delivery
- HIPAA, PCI, SOC 2 ready
- Code in your own GitHub/ GitLab
- CI/CD with 90%+ test coverage
- AWS/GCP certified engineers
Our backend development process
We follow a four-phase process that turns your idea into a production-ready system.
Phase 1 (Discovery): We map your use cases, data models, and integration points. This takes 1-2 weeks and results in a technical specification.
Phase 2 (Architecture): We choose the stack (Node.js vs Go, PostgreSQL vs MongoDB, monolithic vs microservices) and present options with cost and timeline trade-offs.
Phase 3 (Build): We develop in 2-week sprints with continuous deployment. You see working endpoints every sprint and can adjust priorities.
Phase 4 (Deploy): We set up monitoring (Datadog, Sentry), load testing (k6), and security scanning (Snyk). Then we hand over full documentation.
What ships with every backend
Full ownership and professional-grade tooling. You get everything needed to run and extend the system.
Every IRPR backend includes source code, infrastructure-as-code scripts, API documentation (OpenAPI/Swagger), and a runbook for operations. We also set up error tracking (Sentry) and performance monitoring (Datadog) with alerting.
- Source code in your private GitHub/ GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Cloud infrastructure as Terraform files
- API documentation (OpenAPI 3.0 / Swagger UI)
- Automated test suite (unit, integration, e2e)
- Sentry error tracking and Datadog monitoring
- Postman collection for manual testing
- Database migration scripts (Prisma / Flyway)
- Deployment runbook with rollback instructions
- 1 month of post-launch support and bug fixes
What we ship in this practice.
Payment Gateway API
Built a PCI-compliant payment gateway that processes $2M monthly. Reduced transaction failures by 40% using idempotency keys and retry logic. Tech: Go, PostgreSQL, Stripe Connect, AWS Lambda.
Healthcare FHIR API
Developed a FHIR R4 server for a telemedicine platform. Integrated with 3 EHRs (Epic, Cerner, Athenahealth), saving each provider 10 hours per week on data entry. Tech: Node.js, HAPI FHIR, MongoDB, Azure.
Multi-Vendor Marketplace Backend
Built inventory, order, and payment APIs for a marketplace with 500+ vendors. Handled 100K daily requests with sub-200ms latency. Tech: Node.js, PostgreSQL, Redis, Kubernetes.
Usage-Based Billing Engine
Created a metering and billing system for a SaaS company. Generates accurate invoices for 10K+ customers with 99.99% uptime. Tech: Python, Django, TimescaleDB, Stripe.
Real-Time Fleet Tracking
Built a WebSocket backend for a logistics firm to track 2,000 vehicles in real time. Reduced fuel costs by 15% through optimized routing. Tech: Node.js, Socket.IO, Redis, AWS ECS.
Personalization Engine API
Designed a recommendation API for an ecommerce brand. Increased average order value by 22% using collaborative filtering and real-time inventory checks. Tech: Go, PostgreSQL, Redis, Elasticsearch.
Why teams hire us.
Fixed price, not hourly
Every backend project gets a fixed quote in the Roadmap phase. No hourly billing means no surprise costs. Prices start at $80K for a full backend system.
2-week kickoff
We can start your project within 2 weeks of signing. Our engineering team works async-first, with daily overlap hours for US and European clients.
Full code ownership
You own all source code, scripts, and documentation. We never lock you into proprietary frameworks or hosting. Code lives in your repository from day one.
Dedicated engineering lead
A senior backend engineer leads your project from start to finish. They write code, review PRs, and communicate directly with your team via Slack and weekly calls.
Compliance built-in
We embed HIPAA, PCI-DSS, or SOC 2 controls from architecture to deployment. Our engineers hold certifications and regularly handle audit-ready systems.
Post-launch support
Every project includes 1 month of post-launch support. We fix bugs, monitor performance, and help your team take over. Extended support plans are available.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
