Best Custom Backend Development ConsultantsBackend Development
We build production-ready backend systems in 8-12 weeks. Fixed pricing from $80K with full code ownership.
IRPR builds custom backend systems using Node.js, Go, Python, PostgreSQL, Redis, and Kafka. We design APIs, microservices, and real-time data pipelines that handle millions of requests per day.
Every backend ships with CI/CD pipelines, Docker containers, Kubernetes orchestration, and monitoring (Datadog, Sentry). Delivery takes 8-12 weeks with fixed pricing from $80K to $250K. We comply with HIPAA, PCI-DSS, and SOC 2 out of the box.
CTOs hire us to replace fragile legacy backends. Startup founders engage us for their first production API. Enterprise teams bring us in for scalable architecture design. Product managers trust us to deliver on time and on budget.
Types of software we ship.

Why IRPR is the Best Custom Backend Development Consultant
We have shipped over 200 backend systems across 50 countries with a 98% on-time record.
Our backend consultants average 10+ years of experience. We use proven patterns: event sourcing, CQRS, and clean architecture. Every project starts with a detailed Roadmap phase where we define the data model, API contracts, and deployment strategy.
We do not use offshore teams or junior developers. Every engineer on your project has built production systems at scale. We test for 99.9% uptime, run load tests with k6, and set up error tracking with Sentry before the first release.
Generic Dev Shop vs. IRPR: The Difference
Most agencies bill hourly and deliver late. IRPR works differently.
A generic dev shop starts coding before understanding your data model. They use whatever stack they know, skip documentation, and hand you code you cannot maintain. You pay for every hour, even when they learn on the job.
IRPR starts with a Roadmap phase where we define every API endpoint, database table, and integration. We use a fixed price based on that Roadmap. You get clean code, CI/CD pipelines, and full documentation. No surprises.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- No CI/CD or monitoring setup
- Code delivered without tests
- You own nothing until final payment
- Fixed price from $80K
- Senior engineers only (10+ years)
- HIPAA, PCI-DSS, SOC 2 built in
- CI/CD, Docker, Kubernetes included
- Unit, integration, and load tests
- Full code ownership from day one
Our Backend Development Process
We follow a four-phase process that delivers a production-ready backend in 8-12 weeks.
Phase 1: Discovery. We map your requirements, data flows, and integrations. You get a detailed Roadmap with timeline and fixed price. This phase takes 1-2 weeks.
Phase 2: Architecture. We design the system: database schema, API contracts, service boundaries, and deployment topology. You review and approve before any code is written.
What Ships with Every Backend Project
Every project includes a complete set of production-grade deliverables, not just code.
We ship source code in your private GitHub repository from day one. The CI/CD pipeline runs tests, builds Docker images, and deploys to staging automatically. You can see the pipeline status at any time.
All infrastructure is defined as code using Terraform. You can recreate the entire environment in a new region with one command. We also include a runbook for on-call engineers.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker images for every service
- Kubernetes manifests (Helm charts)
- Terraform scripts for cloud infrastructure
- PostgreSQL schema migrations (Flyway or Alembic)
- API documentation (OpenAPI/Swagger)
- Unit tests (coverage > 80%)
- Integration tests with testcontainers
- Sentry error tracking and Datadog monitoring
What we ship in this practice.
Real-Time Analytics Backend for Fintech
Built a streaming data pipeline using Kafka and Flink that processes 10,000 transactions per second. Reduced reporting latency from 24 hours to under 1 minute. Tech stack: Go, Kafka, Flink, Redis, PostgreSQL.
HIPAA-Compliant Patient Portal Backend
Designed a secure API for a telehealth platform handling PHI. Implemented BAA-compliant storage and audit logging. Achieved HIPAA readiness in 10 weeks. Tech stack: Node.js, PostgreSQL, AWS S3, Auth0.
Multi-Tenant SaaS Backend for B2B CRM
Architected a database-per-tenant model with automated provisioning. Supported 500+ tenants on a single cluster with no cross-tenant data leaks. Tech stack: Python, FastAPI, PostgreSQL, Terraform, Kubernetes.
Payment Processing Backend for Ecommerce
Integrated Stripe, PayPal, and Square into a unified payment API. Handled 50,000 transactions per day with idempotency and retry logic. Reduced failed payments by 30%. Tech stack: Node.js, PostgreSQL, Redis, Stripe.
Legacy Migration Backend for Real Estate
Migrated a monolithic MLS system to microservices. Extracted listing search, user management, and analytics into separate services. Cut deployment time from 4 hours to 15 minutes. Tech stack: Go, gRPC, PostgreSQL, NATS.
IoT Data Ingestion Backend for Manufacturing
Built a high-throughput ingestion service for 10,000 sensors. Used MQTT and Kafka for real-time processing and anomaly detection. Reduced data loss to 0.01%. Tech stack: Rust, Kafka, InfluxDB, Grafana.
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 exact cost before we write a single line of code.
Senior Engineers Only
Every engineer on your project has 10+ years of experience. We do not use juniors or offshore teams. Your project is led by a principal engineer who has shipped at least 5 production backends.
8-12 Week Delivery
We ship in 8-12 weeks because we use proven patterns and reusable components. Our average delivery time across 200+ projects is 11.4 weeks. We have never missed a deadline by more than 1 week.
Full Code Ownership
You own the source code, infrastructure scripts, and documentation from day one. There is no licensing fee, no ongoing royalty, and no lock-in. You can take the code to any team after the project.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from the start. Our systems pass audits without last-minute fixes. We have delivered compliant backends for 30+ healthcare and fintech companies.
Async-First Communication
We work async with daily standups and weekly demos. No micromanagement or endless meetings. You get a Slack channel, a Notion project board, and a weekly progress report. Overlap hours cover US and European time zones.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
