Best Python App Development FirmApp Development
We build production-grade Python apps in 8-12 weeks. Fixed price, senior engineers only.
IRPR is the best python app development firm for teams that need fast, reliable, and scalable software.

Every project ships with a CI/CD pipeline, automated tests, and cloud infrastructure on AWS or GCP.
Our typical engagement delivers a production-ready MVP in 8 to 12 weeks. Pricing is fixed at $80,000 to $250,000 depending on scope. We handle compliance: HIPAA for healthcare, SOC 2 for SaaS, PCI-DSS for fintech. You get full source code ownership and a 12-month warranty on all code.

Our python app development process
We follow a 4-phase process: Idea, Roadmap, Product, Release.
In the Idea phase, we define the product vision, user stories, and technical requirements. This takes 1 week. You get a product brief and a technical feasibility assessment.
In the Roadmap phase, we create wireframes, a database schema, and a fixed-price quote. This takes 1 week. You get a detailed plan and a guaranteed price. The Product phase builds the app in 6-10 weeks with weekly demos. The Release phase deploys to production and includes a 12-month warranty.
