Experienced Python Backend Development ConsultantsPython Backend
We build production-ready Python backends for startups and enterprises. Get a fixed-price quote in your second week.
IRPR builds scalable Python backends for web apps, APIs, and data services. We use Django, FastAPI, Flask, PostgreSQL, Redis, and AWS Lambda to deliver systems that handle millions of requests per day.
Every project ships in 8-12 weeks. Pricing starts at $80K and goes up to $250K for complex systems. We handle HIPAA, PCI-DSS, and SOC 2 compliance requirements.
We work with CTOs needing to scale their backend, founders launching SaaS MVPs, enterprise teams migrating legacy systems, and product managers adding API features.

Why IRPR for Python Backend Development
We have shipped over 200 custom backends with Python.
Our team of senior engineers averages 10+ years of Python experience. We have built backends for fintech platforms processing $50M+ per month and healthcare systems handling millions of patient records.
Every project goes through a structured Roadmap phase where we define architecture, select tech stack, and produce a fixed-price quote. Our on-time delivery rate is 98%.
The IRPR Difference for Python Backend Consulting
Not all Python consultants deliver production-ready code.
Generic dev shops often produce untested code with no monitoring or scaling plan. They may use outdated libraries and leave you with technical debt.
IRPR builds your backend with CI/CD, automated testing, monitoring (Sentry, Datadog), and infrastructure as code from day one. You own the code and can deploy independently.
- Uses Flask for everything, even when it's wrong
- No automated tests, just manual QA
- No Docker or Kubernetes setup
- No API documentation
- No CI/CD pipeline
- No monitoring or error tracking
- Selects right framework: Django vs FastAPI vs Flask per use case
- 95%+ test coverage with pytest
- Docker containers with Kubernetes orchestration
- Auto-generated OpenAPI docs
- GitHub Actions CI/CD
- Sentry + Datadog monitoring included
Our Python Backend Development Process
We move from idea to production in 4 phases.
Each phase has clear deliverables and a fixed scope. You see progress every week.
What Ships with Every Python Backend
Every project includes these deliverables by default.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker containers with Docker Compose and Dockerfile
- Kubernetes manifests (optional)
- Automated test suite with pytest (95%+ coverage)
- API documentation via Swagger/OpenAPI
- Error tracking with Sentry
- Application monitoring with Datadog or Prometheus
- Database migration scripts (Alembic for SQLAlchemy)
- Deployment playbook and runbook
What we ship in this practice.
Real-time Payment Processing Backend
Built a FastAPI backend for a fintech startup processing 10,000+ transactions per minute. Integrated Stripe, Plaid, and custom KYC flows. Reduced chargeback rate by 40% with real-time fraud detection.
Healthcare Data Exchange API
Developed a HIPAA-compliant Django backend for a telemedicine platform. Handled 500,000+ patient records and integrated with Epic EHR. Achieved 99.99% uptime with AWS Lambda and RDS.
SaaS Multi-Tenant Backend
Built a Django REST backend with tenant isolation for a B2B SaaS. Used PostgreSQL schemas and Redis caching. Supported 200+ tenants with auto-scaling to handle peak loads.
E-commerce Inventory Management
Created a FastAPI microservice for a multi-vendor marketplace. Integrated with warehouse APIs and provided real-time stock updates via WebSockets. Reduced inventory sync time from 2 hours to 30 seconds.
Real Estate Listings API
Built a Python backend for a real estate platform aggregating MLS data from 50+ sources. Used Celery for background processing and Elasticsearch for full-text search. Cut listing refresh latency by 70%.
Learning Management System Backend
Developed a Django backend for an edtech platform serving 100,000+ students. Integrated with Canvas LMS via API and implemented custom quiz analytics. Reduced page load times by 60% with CDN caching.
Why teams hire us.
Senior Engineers Only
Every Python consultant at IRPR has 10+ years of experience. We do not staff juniors or offshore teams. Your project is built by engineers who have shipped production backends for companies like Stripe and AirBnB.
Fixed Price from Week 2
After the Roadmap phase, you get a fixed price for the entire project. No hourly billing, no surprises. If scope changes, we adjust the price before starting new work.
Full Code Ownership
You own all source code, documentation, and infrastructure scripts. We deploy to your AWS or GCP account. There are no licensing fees or lock-in.
Production-Ready from Day One
Your backend ships with CI/CD, monitoring, error tracking, and automated tests. You can deploy changes after we hand over the project without relying on us.
Compliance Built In
We handle HIPAA, PCI-DSS, and SOC 2 requirements as part of the build process. No afterthought audits. We include encryption, access controls, and audit logging.
98% On-Time Delivery
Our structured Roadmap phase eliminates scope creep. We deliver every milestone on schedule. In 200+ projects, 98% shipped within the agreed timeline.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
