Experienced Python Backend Development Vendor That ShipsThat Ships
We build production-grade Python backends for SaaS, fintech, and data-heavy apps. 200+ products shipped with zero scope creep.
IRPR builds Python backends using Django, FastAPI, Celery, Redis, and PostgreSQL. Our senior engineers design async architectures that handle 10,000+ requests per second.
We ship in 8-12 weeks with fixed pricing between $80,000 and $250,000. Every backend ships with HIPAA, PCI-DSS, and SOC 2 compliance built in from day one.
CTOs scaling SaaS platforms hire us to replace fragile microservices. Fintech founders need our PCI-compliant payment backends. Healthcare startups require HIPAA-compliant patient data APIs. Enterprise teams use us to modernize legacy Java and .NET systems.
Types of software we ship.
REST API Backend
Build CRUD APIs with Django REST Framework or FastAPI. Supports pagination, rate limiting, and JWT auth.
GraphQL API Backend
Use Strawberry or Ariadne for GraphQL endpoints. Reduce overfetching and speed up mobile clients.
Real-Time Data Pipeline Backend
Stream events through Kafka, RabbitMQ, or Redis Streams. Process 50,000 events per second.
Microservices Backend
Deploy containerized services with Docker and Kubernetes. Each service scales independently.
Event-Driven Backend
React to events with Celery tasks and AWS SQS. Handle async workflows like email sending and report generation.
Async Task Queue Backend
Offload heavy work to Celery workers with Redis or RabbitMQ. Reduce response times from 10 seconds to 200ms.
Auth and Identity Backend
Implement OAuth2, OpenID Connect, and SAML with Auth0 or custom JWT. Supports multi-tenancy and RBAC.
Data Ingestion Backend
Ingest CSV, JSON, and API data using Pandas and Airflow. Land 1 million rows per hour into PostgreSQL.
We build for every business type.
SaaS Platforms
Fintech Companies
Healthcare Providers
E-Commerce Brands
Data-Intensive Applications
Why Your Next Python Backend Needs an Experienced Vendor
Building a Python backend that scales requires deep expertise in async, caching, and database optimization.
A generic developer might cobble together Flask, SQLite, and no tests. Within six months you get slow endpoints, memory leaks, and a database that locks up under load. IRPR builds backends that handle 10x traffic without rewrites.
We design for horizontal scaling from day one: load balancers, read replicas, Redis caching, and Celery workers. Every project ships with load testing results and a scaling plan.
Generic Shop vs. Experienced Python Vendor
Not all Python developers are equal. The difference shows in performance, compliance, and delivery time.
A generic dev shop assigns a single junior developer who bills hourly. They copy code from tutorials and ignore async patterns. The result is a backend that breaks under load and fails audits.
IRPR assigns a team of two senior engineers who have built backends for fintech, healthcare, and SaaS. Every line of code is reviewed, tested, and documented.
- Hourly billing, no fixed price
- Unclear code ownership
- No compliance expertise
- No async or performance optimization
- No CI/CD or monitoring
- Single junior developer assigned
- Fixed price from Roadmap phase
- Full code ownership
- HIPAA, PCI, SOC 2 built in
- Async with FastAPI, Celery, Redis
- GitHub Actions CI/CD, Sentry monitoring
- 2 senior engineers, 2+ week overlap
Our 4-Phase Process for Python Backend Delivery
We follow a repeatable process to de-risk your project and ship on time.
Each phase includes clear deliverables and sign-offs. You never pay for work that doesn't meet the spec.
What Ships with Every Python Backend
Every project includes these deliverables by default. No hidden extras.
All code and infrastructure is yours from day one.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error and performance monitoring
- Docker containers for local development
- API documentation (Swagger / OpenAPI)
- Database migration scripts (Alembic)
- Unit and integration tests (pytest, 80%+ coverage)
- Production deployment config (AWS, GCP, or Azure)
- Post-launch runbook
- Knowledge transfer session with your team
What we ship in this practice.
Event-Driven Analytics Pipeline
IRPR built a real-time analytics pipeline for a SaaS analytics platform using Kafka, Apache Flink, and PostgreSQL. The system ingests 500,000 events per second and reduced query response time from 5 seconds to 300ms.
Real-Time Chat Backend
We built a WebSocket-based chat backend with FastAPI and Redis Pub/Sub for a customer support startup. It handles 50,000 concurrent connections with message delivery latency under 100ms.
Payment Processing Microservice
IRPR developed a PCI-DSS compliant payment microservice using Django and Stripe Connect. It processes 10,000 transactions per day and completed a SOC 2 Type II audit within 3 months.
HIPAA-Compliant Patient Data API
For a telemedicine startup, we built a HIPAA-compliant API with FastAPI, PostgreSQL, and AWS HealthLake. The system stores 2 million patient records and passes annual audit review.
Multi-Tenant SaaS Auth
IRPR built a multi-tenant authentication system with Auth0 integration and custom JWT for a B2B SaaS. It supports 500 tenants, each with isolated user pools and role-based access control.
Image and Video Processing Pipeline
We built an async pipeline using Celery, AWS Lambda, and FFmpeg for a media company. It processes 10,000 video files per day and reduced processing time by 60% compared to their old PHP system.
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.
Senior Engineers Only
We assign two senior engineers with 10+ years of Python experience. No junior developers, no offshore teams, no code dropped over a wall.
Compliance Built In
HIPAA, PCI-DSS, and SOC 2 compliance are included from the architecture phase. We provide BAAs, encryption at rest, and audit logging out of the box.
Async-First Architecture
We use FastAPI, Celery, and Redis for non-blocking performance. Your backend handles 10,000 concurrent requests without spawning new threads.
Full Code Ownership
You own every line of code, every Dockerfile, and every config file. No licenses, no restrictions, and no monthly fees for using our code.
Post-Launch Monitoring Included
We set up Sentry, Grafana, and PagerDuty alerts before go-live. You get 30 days of monitoring support free after launch.
