Senior Python App Development AgencyPython App
We build production-grade Python apps with senior engineers. 12-week MVPs, fixed pricing, full code ownership.
IRPR builds custom Python applications using Django, FastAPI, Flask, and AWS. We handle everything from REST APIs to data pipelines, AI backends, and real-time systems.
Every project ships in 12 to 14 weeks with fixed pricing from $80,000 to $250,000. Compliance for HIPAA, PCI-DSS, and SOC 2 is included in every engagement.
We work with CTOs who need a reliable Python backend for their platform, SaaS founders scaling an MVP to production, enterprise IT directors migrating legacy .NET or Java systems to Python, and healthcare companies requiring HIPAA-compliant Python apps.

Senior Python App Development Agency by the Numbers
Our track record speaks for itself. Every number comes from real projects shipped to production.
IRPR has delivered 200+ products across 50+ countries since 2016. We maintain a 98% on-time delivery rate and 99.9% average uptime across all deployments.
Our clients include Series A SaaS companies, healthcare networks, fintech startups, and logistics firms. The average MVP ships in 12 weeks with a fixed price locked during the Roadmap phase.
Generic Python Agency vs. IRPR: What You Actually Get
Most Python agencies look the same on paper. Here is what changes when you work with senior engineers.
Generic agencies often assign junior developers, use hourly billing, and deliver code you cannot modify. IRPR assigns two senior engineers per project, works on a fixed price, and gives you full ownership of all source code.
Our process includes a 2-week Roadmap phase where we spec the entire application. You know the cost, timeline, and deliverables before we write a single line of code. No surprises.
- junior or mid-level developers assigned
- hourly billing with no cap
- code hosted on their GitLab
- no compliance guarantees
- 12+ month timeline for MVP
- no monitoring or DevOps included
- two senior Python engineers per project
- fixed price quoted in week 2
- code in your GitHub repo day one
- HIPAA / PCI / SOC 2 built in
- 12-week MVP delivery average
- Sentry, Datadog, CI/CD included
Our Process for Building Your Senior Python App
We follow a structured 4-phase framework. Each phase has a clear deliverable before moving forward.
The process starts with a free discovery call where we map your idea to the best Python stack. Then we enter the Roadmap phase and produce a detailed spec with wireframes, data model, and fixed price.
Development runs in 2-week sprints with full visibility. You see progress in a shared Trello board and receive a deployment URL for each sprint. Release includes production deployment, monitoring setup, and documentation.
What Ships with Every Senior Python App
Every project includes these deliverables by default. No add-ons, no hidden fees.
From day one, your code lives in a private GitHub repository that you own. We set up CI/CD with GitHub Actions and deploy to a production AWS environment with auto-scaling.
Monitoring is configured with Sentry for error tracking and Datadog for performance. You receive a full admin dashboard and API documentation generated from FastAPI or Django REST Framework.
- Source code in your GitHub repo (full ownership)
- CI/CD pipeline (GitHub Actions)
- Production AWS environment (EC2, RDS, S3, CloudFront)
- Sentry error tracking
- Datadog performance monitoring
- Auto-generated API docs (Swagger / OpenAPI)
- Docker containers with Docker Compose
- Database migrations (Alembic or Django migrations)
- Admin dashboard (Django Admin or custom React)
- User authentication (OAuth2, JWT)
What we ship in this practice.
Healthcare Data Platform
Built a HIPAA-compliant patient analytics platform with Django and PostgreSQL on AWS. Reduced manual reporting time by 15 hours per week for a 200-bed hospital network.
Fintech Payment Gateway
Developed a PCI-DSS compliant payment processing backend using FastAPI and Stripe Connect. Handles 10,000+ transactions per hour with 99.99% uptime.
SaaS Subscription Manager
Created a multi-tenant subscription billing engine with Django, Celery, and Stripe. The client onboarded 500+ businesses in the first quarter after launch.
Ecommerce Recommendation Engine
Built a real-time product recommendation API using FastAPI and TensorFlow. Increased average order value by 22% for a mid-market retailer.
Logistics Route Optimizer
Designed a route optimization pipeline with Apache Airflow and Google OR-Tools. Reduced delivery fuel costs by 18% for a regional logistics company.
ML Model Serving Platform
Developed a model inferencing API with FastAPI and PyTorch on SageMaker. Serves 1 million predictions per day with sub-50ms latency.
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 exact cost before we start.
Senior engineers only
We employ only senior Python developers with 7+ years experience. No juniors, no outsourcing. Each project has two engineers assigned full-time.
Full code ownership
All source code is delivered to your GitHub repository. You own every line. No license fees, no lock-in, no restrictions on future development.
Compliance built-in
HIPAA, PCI-DSS, and SOC 2 controls are part of our default development process. We handle audit logging, encryption, and access controls from day one.
Async-first collaboration
Our team works across time zones with a 4-hour daily overlap with US clients. You get daily updates on Slack and weekly video demos. No micromanagement needed.
2-week project start
We can kick off most projects within 2 weeks of the signed Roadmap. The discovery call takes one hour, and you get a proposal within two days.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
