Top Python Backend Development ConsultantsBackend Development
We build Python backends that scale. Django, FastAPI, Flask — 8-12 week MVPs with fixed pricing.
IRPR is a team of senior Python backend consultants. We build REST APIs, microservices, and data pipelines using Django, FastAPI, Flask, and PostgreSQL. Every project starts with a clear roadmap and ends with production-ready code.
We ship MVPs in 8-12 weeks. Fixed pricing starts at $80K and goes to $250K for complex systems. Our backends handle HIPAA, PCI-DSS, and SOC 2 compliance. We integrate with Stripe, Twilio, AWS, and Google Cloud.
CTOs hire us when their in-house team lacks Python depth. Startup founders hire us to build their first backend fast. Product managers hire us to add API layers to existing systems. Each gets a senior engineer who writes clean, testable Python.

Why hire top Python backend development consultants
You need a backend that works under load and ships on time.
IRPR's senior engineers have built backends for 200+ products across 50 countries. We use Django for complex data models, FastAPI for high-performance APIs, and Flask for lightweight services. Every project includes automated tests, CI/CD pipelines, and monitoring with Sentry and Datadog.
Our consultants write Python that is clean, typed, and documented. We use Pydantic for validation, SQLAlchemy for ORM, and Alembic for migrations. You get code that another engineer can read and maintain without a manual.
How IRPR differs from other Python backend consultants
Most agencies charge hourly and deliver late. We don't.
Generic dev shops start coding without a plan. They use different coding standards on every project. They bill for every email and meeting. IRPR works differently.
We start with a 2-week Roadmap phase where we spec the entire backend. You get a fixed price and timeline before we write a single line of code. Every project includes a senior engineer who stays until launch.
- Hourly billing with no cap
- No roadmap before coding
- Junior developers on your project
- No automated testing
- No CI/CD pipeline
- You own nothing until full payment
- Fixed price from day one
- 2-week Roadmap phase with full spec
- Senior engineers only (10+ years)
- 100% test coverage on critical paths
- CI/CD with GitHub Actions and Docker
- Full code ownership from day one
Our Python backend development process
We build backends in 4 phases. Each phase has a clear deliverable.
Phase 1: Roadmap. We meet with your team, review your requirements, and produce a detailed technical spec. You get a fixed price and timeline. This takes 2 weeks.
Phase 2: Build. Our senior engineers write the backend using Django, FastAPI, or Flask. We set up the database, API endpoints, authentication, and integrations. You see progress every week.
What ships with every Python backend project
You get more than code. You get a production-ready system.
Every project includes a complete deployment setup. We use Docker containers, AWS ECS or Google Cloud Run, and a PostgreSQL database. Your team can deploy new versions with one command.
We include automated tests with pytest, code coverage reports, and API documentation with Swagger. Your frontend team can start integrating immediately.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker Compose for local development
- PostgreSQL database with migration scripts
- API documentation with Swagger/OpenAPI
- Automated tests with pytest (90%+ coverage)
- Sentry error tracking
- Datadog monitoring dashboard
- Deployment guide and runbook
- 30-day post-launch support

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we start.
Senior engineers only
Every consultant has 10+ years of Python experience. No juniors, no offshore teams, no handoffs. The same engineer who designs the backend builds and deploys it.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Your team can start integrating on day one. We have shipped 200+ products on time.
Full code ownership
You own the code from day one. We put it in your GitHub repo. No licensing fees, no vendor lock-in. You can take it anywhere.
Compliance built in
We build backends that pass HIPAA, PCI-DSS, and SOC 2 audits. We use encryption, access controls, and audit logs. Your compliance team will approve.
Post-launch support included
Every project comes with 30 days of support after launch. We fix bugs, answer questions, and help your team take over. No extra charge.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
