Why choose IRPR for Python application development
Our numbers speak for themselves.
We have delivered over 200 Python applications across 50 countries with a 98% on-time track record. Our clients range from funded startups to Fortune 500 enterprises.
Every project includes a dedicated project manager, bi-weekly demos, and a 12-month warranty on code. We do not bill by the hour — every scope has a fixed price locked in week 2.
How we differ from other Python development firms
We are a senior-only team with no junior developers. Every engineer has 8+ years of experience.
Most Python agencies staff with mixed skill levels and bill hourly. We assign a lead architect who stays until delivery. Our fixed-price model means you never pay for learning curves or miscommunication.
We also lead with compliance out of the box. If you need HIPAA or SOC 2, we build every endpoint with audit logs, encryption, and access controls from day one.
- Billing by hour with no cap
- Junior engineers learning on your dime
- No compliance expertise until audit
- Unclear timeline with scope creep
- Handoff after code delivery, no warranty
- No dedicated project manager
- Fixed price locked in week 2
- Senior engineers only (8+ years avg.)
- Built-in HIPAA, SOC 2, PCI compliance
- 8-12 week delivery with clear milestones
- 12-month code warranty and support
- Dedicated PM with weekly updates
Our 4-phase approach to building your Python app
We start with a discovery call and ship code in week 3. Here is how we deliver.
Phase 1: Idea. We map your requirements to a functional specification. Phase 2: Roadmap. We lock scope, cost, and timeline with a fixed-price contract. Phase 3: Product. We build your app in sprints with bi-weekly demos. Phase 4: Release. We deploy, monitor, and hand over full ownership.
Each phase ends with a deliverable. You see working code every two weeks. No black boxes, no surprises.
What you receive when we build your Python app
Full code ownership, zero lock-in.
You get the complete source code in your own GitHub repository. We set up CI/CD with GitHub Actions, automated tests, and code coverage reports. You can run your app anywhere — no proprietary frameworks, no hidden dependencies.
We also configure Sentry error tracking, Datadog performance monitoring, and structured logging. Your team can take over maintenance immediately or we can stay on as a retainer.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (80%+ coverage)
- Sentry error tracking with alerting
- Datadog or CloudWatch monitoring dashboard
- Structured logging with JSON output
- Docker containers for every service
- Deployment scripts for AWS (ECS/EKS or EC2)
- Documentation: README, API docs (Swagger), architecture diagram
- 12-month warranty on all code
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project receives a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of Python experience. We do not hire junior developers or outsource to offshore shops. Every engineer has shipped at least 10 production Python applications.
Built-in compliance
We handle HIPAA, SOC 2, PCI-DSS, and FERPA from day one. Every endpoint uses encryption, audit logging, and role-based access. No expensive retrofits later.
98% on-time delivery
Over 200 projects completed on schedule. We use sprints, milestone tracking, and a dedicated project manager to keep delivery predictable.
Dedicated project manager
A single PM owns your project from kickoff to release. You get weekly status reports, a Slack channel, and direct access to the lead engineer.
12-month warranty
We fix any bugs or performance issues for free for one year after launch. No hidden retainers. If the app breaks, we fix it at no cost.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
