Custom Backend Development AgencyDevelopment Agency
We build server-side systems that scale. Get a custom backend in 8-12 weeks with fixed pricing.
IRPR builds custom backend systems for SaaS platforms, fintech apps, and data-heavy services. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to create APIs, microservices, and event-driven architectures.
Every project ships in 8-12 weeks with a fixed price from $80K to $250K. We handle compliance like HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code, CI/CD, and monitoring built in.
Founders scaling their MVP, CTOs replacing legacy infrastructure, product managers launching new features, and enterprise architects migrating to microservices hire us.
Types of software we ship.
REST API Development
Build stateless APIs for web and mobile clients. Includes OpenAPI spec, rate limiting, and JWT auth.
Microservices Architecture
Decompose monoliths into independent services. Uses gRPC, message queues (RabbitMQ), and container orchestration with Kubernetes.
GraphQL API Development
Build flexible APIs with Apollo Server or Hasura. Clients query exactly what they need, reducing over-fetching.
Event-Driven Systems
Process asynchronous events with Apache Kafka or AWS SQS. Ideal for real-time data pipelines and notifications.
Backend for Mobile Apps
Server-side logic for iOS and Android apps. Includes push notifications, file uploads, and social login via Firebase.
Real-Time Backend
WebSocket servers for live chat, collaborative editing, or live dashboards. Built with Socket.io or AWS API Gateway WebSockets.
Data Pipeline & ETL
Extract, transform, load data between systems. Uses Airflow, dbt, and custom connectors for CRM, ERP, and analytics.
Admin Dashboard Backend
Internal tools with user management, role-based access, and audit logs. Built with Django Admin or custom React frontends.
We build for every business type.

Why you need a custom backend development agency
Off-the-shelf backends fail at scale.
Generic backends like Firebase or AWS Amplify work for prototypes but break under complex business logic. You need a system built for your data model, compliance, and performance requirements.
IRPR has shipped 200+ custom backends across 50 countries. We use Node.js, Python, and Go with PostgreSQL, Redis, and Kafka. Each project gets auto-scaling, monitoring (Datadog), and CI/CD (GitHub Actions).
How IRPR differs from other backend agencies
Most agencies bill hourly and hand you code with no DevOps.
Generic shops use boilerplate templates and overcharge for changes. They don't set up monitoring, logging, or CI/CD unless you pay extra. You get code that works on their machine.
IRPR delivers a production-ready system. We include Sentry error tracking, Datadog monitoring, GitHub Actions CI/CD, and infrastructure as code (Terraform) by default. No surprises.
- Hourly billing with scope creep
- No monitoring or alerting
- Manual deployments
- No API documentation
- Shared hosting, no autoscaling
- No post-launch support SLA
- Fixed price from day one
- Sentry + Datadog included
- Automated CI/CD via GitHub Actions
- OpenAPI spec auto-generated
- AWS/GCP with auto-scaling
- Post-launch support with 24hr SLA
Our backend development process
We follow a structured 4-phase framework.
Phase 1: Idea. We map your data model, business rules, and API contracts in week 1. You get a detailed specification and fixed quote before any code is written.
Phase 2: Roadmap. We break the project into 2-week sprints with clear deliverables. Each sprint ends with a demo and deployable code.
What ships with your custom backend
You own everything. No lock-in.
When we finish, you get a production-ready backend with all the infrastructure code. You can host it anywhere, modify it freely, and scale without us.
We set up monitoring alerts, error tracking, and log aggregation. Your team gets on-call runbooks and a support SLA.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline (GitHub Actions)
- Infrastructure as code (Terraform)
- Monitoring dashboard (Datadog)
- Error tracking (Sentry)
- Load testing report (k6)
- Deployment runbook
What we ship in this practice.
Real-time fraud detection API for a fintech startup
Built a WebSocket service that processes 10,000 transactions/minute with less than 100ms latency. Uses Go, Redis, and Kafka. Reduced false positives by 40%.
Microservices backend for a SaaS analytics platform
Decomposed a monolith into 12 services using Node.js, PostgreSQL, and RabbitMQ. Cut deployment time from 4 hours to 15 minutes.
HIPAA-compliant backend for a telemedicine app
Built a secure API for video consultations, EHR sync, and prescription management. Used Python, FastAPI, and AWS HealthLake. Passed HIPAA audit on first try.
Scalable order management system for an ecommerce brand
Designed an event-driven backend with Go and Kafka. Handles 50,000 orders/day during Black Friday. Integrated with Shopify and ShipStation.
Backend for a real estate MLS platform
Built a GraphQL API serving 1M property listings. Used Apollo, PostgreSQL with PostGIS, and Elasticsearch for search. Reduced page load from 4s to 0.8s.
Data pipeline for a logistics company
Created an ETL pipeline processing 5M tracking events daily. Used Airflow, Python, and Snowflake. Consolidated 3 legacy systems into one.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost upfront.
8-12 week delivery
We ship in 8-12 weeks, not months. Our team of senior engineers works full-time on your project. We have a 98% on-time delivery rate across 200+ projects.
Full code ownership
You own all source code, documentation, and infrastructure scripts. No licensing fees, no platform lock-in. You can take the code anywhere after launch.
Production-ready from day one
We include monitoring (Datadog), error tracking (Sentry), CI/CD (GitHub Actions), and infrastructure as code (Terraform). Your backend is ready for production on day 1.
Compliance built in
We build for HIPAA, PCI-DSS, SOC 2, FERPA, and GDPR. Our team includes compliance engineers who audit every endpoint and data flow. We have passed audits for 50+ clients.
Senior engineers only
We only staff engineers with 8+ years experience. No juniors, no offshoring. Your project is managed by a tech lead with deep expertise in your stack.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
