Experienced Python Backend Development ServicesBackend Development
We build Python backends that scale to 1M+ users. 8-12 week MVPs with fixed pricing.
IRPR builds experienced Python backend development services for companies that need reliable, scalable server-side systems. We use FastAPI for async APIs, Django for admin-heavy apps, and PostgreSQL for data persistence.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. You get full ownership of the code and a CI/CD pipeline on GitHub Actions.
Founders needing a SaaS MVP, CTOs scaling a fintech platform, and product managers launching a healthcare data pipeline hire IRPR. They want senior engineers who ship fast without surprises.
Types of software we ship.
REST API development
Build RESTful APIs with FastAPI or Django REST Framework. Includes Swagger docs, rate limiting, and JWT auth.
GraphQL API development
Build GraphQL endpoints with Strawberry or Graphene. Supports real-time subscriptions and batch queries.
Data pipeline development
Build ETL pipelines with Apache Airflow or Prefect. Handles data ingestion from 10+ sources into a data warehouse.
Microservices architecture
Design and deploy microservices with Docker and Kubernetes. Each service has its own database and API.
Background job processing
Build job queues with Celery or RQ. Processes tasks like email sending, file conversion, and report generation.
Webhook integration
Build webhook receivers and senders with FastAPI. Validates payloads, retries failures, and logs events.
Authentication and authorization
Implement OAuth 2.0, SAML, or JWT-based auth with Auth0 or Okta. Supports role-based access control.
Real-time data streaming
Build real-time streaming backends with WebSockets or Server-Sent Events. Uses Redis Pub/Sub for message distribution.
We build for every business type.
SaaS
Fintech
Healthcare
Ecommerce
Logistics
Why experienced Python backend development services matter
A poorly built backend costs you users and revenue.
We have shipped Python backends for 200+ products across 50 countries. Each backend handles between 10,000 and 1,000,000 daily requests. We use FastAPI for async endpoints, PostgreSQL for transactions, and Redis for caching.
Our engineers write tests for every endpoint. We achieve 95% code coverage on every project. We deploy to AWS or GCP with auto-scaling and 99.9% uptime SLAs.
The difference between generic dev shops and IRPR
Not all Python backend teams deliver the same result.
Generic shops assign junior engineers, use outdated frameworks, and bill by the hour. They often miss deadlines and deliver untested code.
IRPR assigns senior engineers with 10+ years of Python experience. We use FastAPI and Django for modern backends. We ship on time with a fixed price and full test coverage.
- Junior engineers with 2 years of experience
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No security audit
- Code ownership unclear
- Senior engineers with 10+ years of experience
- Fixed price from $80K to $250K
- 95% test coverage minimum
- CI/CD pipeline on GitHub Actions
- Security audit for HIPAA, PCI-DSS, SOC 2
- Full code ownership transferred to you
How we deliver experienced Python backend development services
We follow a 4-phase process that guarantees results.
Every project starts with a 2-week Roadmap phase where we define the architecture, database schema, and API endpoints. You get a detailed specification and a fixed price before we write a single line of code.
The Product phase lasts 6-10 weeks. We build the backend in 2-week sprints. You see working endpoints every 14 days. We deploy to a staging environment after each sprint.
What ships with every Python backend project
You get a production-ready backend, not a prototype.
Every project includes the source code, automated tests, CI/CD pipeline, and deployment configuration. You can deploy to AWS, GCP, or Azure with one command.
We also include monitoring with Sentry for error tracking and Datadog for performance. You get a Grafana dashboard with key metrics like request latency and error rates.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- 95% test coverage with pytest
- API documentation with Swagger UI
- Docker Compose for local development
- Deployment scripts for AWS ECS or GCP Cloud Run
- Sentry error tracking
- Datadog performance monitoring
- Grafana dashboard with latency and error metrics
- Security audit report
What we ship in this practice.

Built a FERPA-compliant backend for an online assessment platform. Supports 10,000 concurrent users. Reduced grading time from 2 days to 10 minutes. Tech stack: Django, PostgreSQL, Celery, AWS.
Why teams hire us.
Senior engineers only
Every engineer on your project has 10+ years of Python experience. No juniors. No outsourcing. You talk directly to the person writing your code.
Fixed price from day one
You get a fixed price quote after the 2-week Roadmap phase. No hourly billing. No surprise invoices. The price covers the full scope.
8-12 week delivery
We ship production-ready backends in 8-12 weeks. You see working endpoints every 2 weeks. No long waits for hidden progress.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture. We handle audits, encryption, and access controls so you don't have to.
Full code ownership
You own every line of code. We transfer the repo to your GitHub account at the end of the project. No licensing fees. No vendor lock-in.
Post-launch support
We provide 30 days of post-launch support for bug fixes and minor changes. After that, you can extend support on a monthly basis.
