Why IRPR is the Best Python App Development Agency
We ship Python apps that work, on time, on budget, with full code ownership.
IRPR has shipped 200+ Python applications for clients in 50 countries. Our senior engineers average 10+ years of Python experience. We use Django for full-stack apps, FastAPI for high-performance APIs, and Flask for lightweight microservices.
Every project starts with a 2-week Roadmap phase where we define the architecture, database schema, API contracts, and deployment plan. You get a fixed price and timeline before any coding begins. No surprises.
Generic Dev Shop vs. IRPR
Not all Python agencies deliver the same result. Here is the difference.
Many Python agencies use junior developers, charge by the hour, and deliver code you cannot maintain. IRPR works differently.
We assign senior engineers only, quote a fixed price upfront, and ship production-grade code with tests, documentation, and deployment scripts.
- junior or mid-level developers
- hourly billing with no cap
- no automated tests
- no CI/CD pipeline
- code owned by agency
- 6-9 month delivery
- senior engineers only (10+ yrs avg)
- fixed price from week 2
- 90%+ test coverage
- CI/CD on GitHub Actions
- full code ownership
- 8-12 week delivery
Our Python App Development Process
A repeatable 4-phase process that eliminates risk and delivers on time.
We follow a structured process from idea to release. Each phase has clear deliverables and a go/no-go decision point.
You stay in control throughout. No black boxes, no surprises.

Full Code Ownership
You own all source code, documentation, and infrastructure from day one. No licensing fees, no vendor lock-in. You can take the code and run with it.
Compliance Built In
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture from the start. No expensive retrofits after launch.
