Python Backend Development AgencyBackend Agency
We build production backend systems in 8-12 weeks. Fixed pricing from $80K with full code ownership.
IRPR builds backend systems using Python frameworks like Django and FastAPI, paired with PostgreSQL, Redis, and cloud infrastructure on AWS or GCP. We focus on API design, database architecture, and scalable deployments.
We deliver production-ready backends in 8-12 weeks, priced between $80,000 and $250,000. Every system is built to meet compliance standards like SOC 2, HIPAA, and PCI-DSS from day one.
Our clients are CTOs who need scalable APIs for their products, founders launching SaaS MVPs, enterprise teams migrating legacy monoliths to microservices, and companies building data-intensive platforms.
Types of software we ship.
REST API Development
Build stateless JSON APIs with Django REST Framework or FastAPI. Includes versioning, rate limiting, and OpenAPI docs.
GraphQL API Development
Implement flexible GraphQL endpoints using Graphene or Strawberry. Optimize queries with DataLoader and connection pooling.
Microservices Architecture
Design event-driven microservices with Celery, RabbitMQ, and Docker. Deploy as Kubernetes pods on AWS or GCP.
Data Pipeline / ETL Systems
Build data ingestion and transformation pipelines with Apache Airflow or Prefect. Handle millions of records daily.
Real-Time Backend (WebSockets)
Add real-time features using Django Channels or FastAPI WebSockets. Integrate with Redis Pub/Sub for low-latency updates.
Authentication & Authorization Systems
Implement OAuth2, JWT, or SAML with Django Allauth or Authlib. Support role-based access control and multi-tenancy.
Payment Processing Backend
Integrate Stripe, Braintree, or Adyen. Handle subscriptions, invoicing, and webhooks with idempotency and error recovery.
Ecommerce Backend (Catalog & Cart)
Build product catalog, shopping cart, and checkout with Django or FastAPI. Connect to inventory and shipping APIs.
We build for every business type.
Ecommerce
SaaS
Fintech
Logistics
Healthcare
How we deliver Python backend development
We ship production backends on time, on budget, with full code ownership.
Every project begins with a 2-week Roadmap phase where we define the API spec, database schema, and infrastructure design. This fixed-price phase produces a detailed plan with timeline and cost guarantee.
During the build phase we work in 2-week sprints with daily standups and weekly demos. Your team sees progress every Friday. We deploy to staging after each sprint, and you test live endpoints throughout.
The IRPR difference
We do not work like traditional agencies. Compare our approach with a generic dev shop.
Generic agencies often start development without a clear specification, leading to scope creep and budget overruns. They bill by the hour and may hand over incomplete code with no deployment setup.
IRPR delivers a fixed-price backend with a written guarantee. We include CI/CD, Dockerization, monitoring, and documentation in every project. You own everything we build.
- No fixed scope -- changes cost extra
- Hourly billing with no cap
- No deployment or CI/CD setup
- Code owned by the agency until final payment
- No compliance guidance
- No post-launch support built in
- Fixed price after 2-week roadmap
- 8-12 week delivery guarantee
- Source code in your repo from day one
- Dockerized, CI/CD pipeline (GitHub Actions)
- Built for HIPAA, PCI-DSS, SOC 2
- 30 days free support after launch
Our Python backend development process
Four distinct phases from idea to production deployment.
Phase 1 (Roadmap) defines everything before we write a line of code. Phase 2 (Build) delivers working software every 2 weeks. Phase 3 (QA) includes automated and manual testing. Phase 4 (Deploy) ships to production with full observability.
What you get when we ship
Every deliverable is concrete. Nothing is left for you to figure out.
Our goal is to hand you a running system that your engineering team can maintain immediately. We provide complete source code, infrastructure as code, and monitoring tools.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker containers and docker-compose files
- Database migration scripts (Alembic or Django migrations)
- API documentation in OpenAPI / Swagger
- Sentry error monitoring pre-configured
- Cloud infrastructure as code (Terraform or CloudFormation)
- Staging and production environments with DNS
- Performance benchmark report (requests per second, latency)
- 30 days post-launch support with SLA
What we ship in this practice.
Real-time order tracking for a logistics platform
Built a FastAPI backend with Redis Pub/Sub for real-time location updates. Reduced order lookup time by 300ms and supported 50,000 concurrent users. Tech stack: FastAPI, PostgreSQL, Redis, AWS ECS.
Subscription billing backend for a SaaS company
Developed a Django backend with Stripe integration, Celery for invoice generation, and a reporting dashboard. Handled 10,000+ concurrent subscribers at launch. Tech stack: Django, PostgreSQL, Celery, Stripe.
Patient management system for telemedicine
Created a HIPAA-compliant backend using FastAPI and AWS HealthLake. Automated appointment reminders via Twilio, reducing no-shows by 80%. Tech stack: FastAPI, PostgreSQL, AWS Lambda, Twilio.
Payment gateway integration for a fintech startup
Built a Flask backend that integrated Stripe Connect, PayPal, and Apple Pay. Processed payments with full PCI-DSS compliance in 4 weeks. Tech stack: Flask, Stripe Connect, PostgreSQL, Docker.
Microservices migration for an ecommerce platform
Migrated a monolithic Django app into 12 microservices deployed on Kubernetes. Reduced deployment time from 2 hours to 5 minutes. Tech stack: Django, Docker, Kubernetes, PostgreSQL, RabbitMQ.
Analytics backend for a real estate CRM
Built a FastAPI backend that aggregated MLS listings into a TimescaleDB time-series database. Queried property trends for 5,000+ agents in real time. Tech stack: FastAPI, TimescaleDB, AWS Lambda, Redis.
Why teams hire us.
Fixed price, not hourly
Every project receives a fixed price after a 2-week Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
8-12 week MVP delivery
From idea to production backend in 8-12 weeks. Our average project ships in 12 weeks for a full-feature backend with integrations.
Senior engineers only
Our team averages 10+ years of backend experience. No junior developers, no outsourcing. Every engineer writes production code.
Full code ownership
You own all source code, Dockerfiles, migration scripts, and infrastructure files. No proprietary frameworks, no locked-in licenses.
Compliance built in
We design for HIPAA, PCI-DSS, and SOC 2 from day one. We handle encryption audit logs, access controls, and data retention policies.
Post-launch support included
Every project includes 30 days of free support with a 4-hour SLA. We also offer retainer packages for ongoing maintenance and feature additions.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
