Premium Python Backend Development ConsultantsDevelopment Consultants
You need a Python backend that scales, not just a prototype. We build production-ready backends with senior engineers in 12 weeks fixed price.
IRPR builds premium Python backends for companies that need reliability, security, and performance. We use FastAPI, Django, PostgreSQL, Redis, and Docker to ship backends that handle 50,000+ requests per second without breaking a sweat.
Every engagement ships a complete backend with CI/CD pipeline, automated testing, and cloud deployment on AWS or GCP. Timeline is 12 to 14 weeks for a typical MVP. Pricing is fixed from $80,000 to $250,000 depending on complexity. We comply with HIPAA, PCI-DSS, and SOC 2 standards.
Our clients include CTOs at Series A startups who need a production backend in 3 months, engineering VPs at healthcare companies migrating from legacy monoliths to Python microservices, and founders building SaaS platforms who want a backend that scales to 100,000 users from day one.
Types of software we ship.
Python REST API Development

Why premium Python backend development consultants matter
A poorly architected Python backend costs you time, money, and customers.
Most agencies hand you a Django app that works during demo but crashes at 500 users. They skip async workers, ignore database indexing, and leave security holes. You end up rewriting the whole thing six months later. That rewrite costs 3x more and kills your launch momentum.
IRPR builds backends that handle 10,000 concurrent requests from day one. We baseline every project with load testing using Locust, enforce strict typing with mypy, and containerize everything with Docker. Our backends ship with Sentry error monitoring and Prometheus metrics out of the box.
How IRPR compares to generic Python agencies
Not all Python backend consultants are the same. Here is the difference.
Generic dev shops quote you per hour and stretch your project to 6 months. They use junior developers who learn Python on your dime. You get a monolithic codebase with no tests and no documentation.
IRPR assigns a senior engineer as your tech lead. We give you a fixed price in week 2 after the Roadmap phase. Your code ships with 90% test coverage, CI/CD on GitHub Actions, and a deployable cloud infrastructure on AWS ECS or GCP Cloud Run.
- Hourly billing with no cap
- Junior developers with no Python experience
- No load testing before launch
- No CI/CD pipeline
- No monitoring or error tracking
- You own nothing but debt
- Fixed price from week 2
- Senior Python engineers with 8+ years
- Load testing with Locust during development
- CI/CD with GitHub Actions and Docker
- Sentry + Prometheus monitoring included
- Full source code ownership
Our process for building premium Python backends
We follow a 4 phase framework that de risks every project.
Phase 1 is the Idea phase. We map your requirements, user flows, and data models in a 1 week design sprint. You get a technical specification with API endpoints, database schema, and infrastructure diagram.
Phase 2 is the Roadmap phase. We write a detailed project plan with milestone dates, a fixed price quote, and a risk register. You approve this before any code is written.
What ships with every Python backend engagement
You get a complete product, not just code.
Every project delivers a production ready Python backend with infrastructure, monitoring, and documentation. You own everything. No vendor lock in, no recurring license fees.
We deploy to your cloud accounts using Terraform. You can hand the project to any internal team after launch. The codebase follows PEP 8 standards and is ready for future development.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions and Docker
- API documentation with OpenAPI (Swagger UI)
- Database schema migrations with Alembic
- Unit tests with pytest (90%+ coverage)
- Load testing report with Locust results
- Cloud infrastructure on AWS or GCP via Terraform
- Monitoring with Prometheus, Grafana, and Sentry
- Deployment runbook with rollback procedures
- 30 day warranty on all delivered code
What we ship in this practice.
Fintech payment processing backend
A lending platform needed a backend to process 10,000 loan applications per day. IRPR built a FastAPI backend with Stripe Connect, PostgreSQL, and RabbitMQ. The system reduced manual review time by 80% and handled $2M in monthly transactions.
Healthcare telemedicine API
A telehealth startup needed a HIPAA compliant backend for video consults and patient records. We built a Django backend with Twilio Video, AWS S3 for storage, and encryption at rest. The platform launched in 10 weeks and onboarded 3,000 providers in the first month.
SaaS analytics dashboard backend
A SaaS company wanted real time analytics for their customer success platform. We built a Python backend with FastAPI, Redis Streams, and ClickHouse for data warehousing. The backend processes 5 million events daily with sub 50ms query times.
Ecommerce multi vendor marketplace
An ecommerce platform needed a backend to connect 500 vendors with a single checkout. IRPR built a Django backend with Elasticsearch for product search, Celery for order processing, and Stripe Connect for payments. Order fulfillment time dropped from 4 hours to 30 minutes.
Real estate MLS integration API
A real estate portal needed to sync property listings from 20 MLS feeds. We built a Python backend with Airflow for ETL pipelines and PostgreSQL with PostGIS for geospatial queries. The system ingests 100,000 listings daily and refreshes in under 15 minutes.
EdTech learning management backend
An education company needed a backend for their online course platform. We built a FastAPI backend with Firebase Authentication, MongoDB for content storage, and AWS CloudFront for video delivery. The system supports 50,000 concurrent students with 99.9% uptime.
Why teams hire us.
Fixed price from week 2
We give you a fixed price after the Roadmap phase in week 2. No hourly billing, no surprise invoices. The price you see is the price you pay, plus or minus agreed scope changes.
