Senior Python Backend Development ServicesBackend Development
Build production-ready APIs and microservices with senior Python engineers. We ship in 12 weeks with full ownership and fixed pricing.
IRPR builds senior Python backend development services for companies that need scalable, secure APIs and data pipelines. We use Django, FastAPI, PostgreSQL, Redis, and Celery to deliver production-ready backends.
Each project ships with source code in your repo, CI/CD pipelines, API documentation, and test coverage. Typical delivery is 12 weeks for an MVP, with pricing from $80K to $250K depending on complexity. We follow SOC 2 and GDPR compliance standards.
We work with CTOs launching SaaS platforms, product managers building data-intensive applications, founders needing custom APIs for mobile apps, and engineering leads migrating legacy systems to modern Python backends.
Types of software we ship.
REST API Development
Build RESTful APIs with Django REST Framework or FastAPI that handle thousands of requests per second with proper authentication and rate limiting.
Microservices Architecture
Design and deploy microservices using Docker, Kubernetes, and message brokers like RabbitMQ for scalable, decoupled systems.
Data Pipeline Engineering
Create ETL pipelines with Apache Airflow or Celery to process millions of records daily from various data sources.
GraphQL API Development
Implement GraphQL endpoints with Graphene-Django or Strawberry to give frontend teams flexible data queries.
Real-Time Backend Systems
Build WebSocket-based systems with Django Channels or FastAPI WebSockets for live notifications and chat applications.
Third-Party API Integration
Integrate external APIs like Stripe, Salesforce, or Twilio with proper error handling, caching, and retry logic.
Backend for Mobile Apps
Develop backend services for iOS and Android apps using Python with token-based authentication and push notifications.
Legacy Backend Migration
Migrate from monolithic PHP or Java backends to modern Python services with zero downtime and data integrity.
We build for every business type.
SaaS
Fintech
Healthcare
Ecommerce
Data-Driven
Why Senior Python Backend Development Matters
Experienced Python engineers reduce technical debt and speed up delivery.
Senior developers bring deep knowledge of Python internals, async patterns, and database optimization. They write code that handles 10x traffic without rewrites.
At IRPR, our senior Python engineers have built backends for 200+ products across fintech, healthcare, and SaaS. We use Django, FastAPI, and Celery to deliver systems that scale from day one.
Senior vs Junior Python Backend Dev
Hiring a senior team saves money long term.
Junior developers often produce code that needs heavy refactoring. Senior engineers design for scale, security, and maintainability from the start.
IRPR only staffs senior Python engineers with 5+ years of experience. You get production-ready code, automated tests, and clear documentation in every project.
- No senior oversight
- Hourly billing with scope creep
- Unclear timeline
- No CI/CD setup
- No API documentation
- Code ownership unclear
- 100% senior engineers
- Fixed price from $80K
- 12-week delivery
- CI/CD on GitHub Actions
- Auto-generated OpenAPI docs
- Full code ownership
Our Process for Python Backend Development
We follow a proven 4-phase approach.
Every project starts with a roadmap phase to define scope, architecture, and timeline. Then we build incrementally with weekly demos.
After release, we provide 30 days of post-launch support. You own the code and can continue with your team or ours.
What Ships in Every Python Backend Project
Every deliverable includes these items.
You get more than just code. We provide everything your team needs to maintain and extend the backend.
No surprises. Every item is listed in the contract before we start building.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated test suite with 80%+ coverage
- API documentation via Swagger/OpenAPI
- Docker containers for local development
- Database schema and migration scripts
- Sentry error tracking integrated
- Logging setup with ELK or Datadog
- Deployment playbook for AWS or GCP
- 30-day post-launch support
What we ship in this practice.
Fintech Payment API
Built a PCI-compliant payment processing API using FastAPI and Stripe. Reduced transaction failures by 40% and cut integration time for merchants from 6 weeks to 2 weeks.
Healthcare Data Pipeline
Developed a HIPAA-compliant ETL pipeline with Apache Airflow and PostgreSQL for a telehealth platform. Processed 500K patient records daily with 99.9% uptime.
SaaS Multi-Tenant Backend
Created a Django-based multi-tenant backend with PostgreSQL schemas for a B2B SaaS. Onboarded 200 tenants in the first 3 months with zero data leaks.
Ecommerce Inventory System
Built a real-time inventory management API using FastAPI and Redis. Synchronized stock across 3 warehouses with sub-second latency. Reduced over-selling by 95%.
Real-Time Chat Backend
Implemented a WebSocket-based chat system with Django Channels for a social media app. Handled 10K concurrent connections with <100ms latency.
Logistics Tracking API
Developed a shipment tracking API using Python and Celery for a logistics company. Integrated with 5 carrier APIs and reduced tracking update delays from 1 hour to 5 minutes.
Why teams hire us.
Fixed Price from Day One
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices. Pricing starts at $80K for an MVP.
Senior Engineers Only
We don't outsource or use junior developers. Every engineer on your project has 5+ years of Python experience and has shipped production backends for 200+ products.
12-Week Delivery Guarantee
We deliver a working MVP in 12 weeks on average. Our process is designed to avoid scope creep and keep the timeline predictable.
Full Code Ownership
You own all source code, documentation, and infrastructure from day one. No licensing fees, no lock-in. You can take the code to any team.
Production-Ready Infrastructure
Every project ships with CI/CD, monitoring (Sentry), logging (Datadog), and automated tests. Your backend is ready for production from the first deployment.
Compliance Built In
We build backends that meet SOC 2, HIPAA, PCI-DSS, and GDPR standards. Our engineers have deep experience with security and compliance requirements.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
