PHP → PYTHON / DJANGO

From legacy PHP to modern Python.

For business applications where the data model and the rules are the product — ERP, CRM, operations and reporting systems. We rebuild them on Django, deliberately and with your domain experts in the room.

§1 WHERE DJANGO FITS

Built for applications that are mostly data and rules.

Django’s ORM, migrations, admin and mature ecosystem suit systems where correctness of the data matters more than novelty of the interface.

1.1

ERP and CRM systems

Customers, orders, stock, approvals — many related entities, many roles.

1.2

Database-heavy applications

Versioned schema migrations replace ad-hoc SQL scripts.

1.3

Complex business logic

Rules extracted from templates into tested service layers.

1.4

Long-term maintainability

Conventional structure that new hires recognize on day one.

§1B THE BUSINESS CASE

Django pays back in the parts of the system nobody sees.

The commercial argument is not speed of the rewrite. It is what the next five years cost to run, change, audit and staff.

OPERATING COST

Back-office screens you don’t build

The built-in admin covers most internal data management, so budget goes to the parts customers touch.

CHANGE COST

Rules you can change safely

Pricing, approvals and permissions live in tested code, so a policy change is a release — not a risk.

AUDIT & SECURITY

Safer defaults, fewer findings

Parameterized queries, CSRF protection and long-term-support releases are standard, not bolted on.

STAFFING

A hiring pool that keeps growing

Python is widely taught and used beyond the web, so the system no longer depends on one person.

Return depends on your codebase. The Assessment Report states effort, risk and phasing for your system before any commitment.

§2 PHP VS DJANGO

What changes, concern by concern.

Typical patterns in legacy PHP codebases and their Django counterparts. Your Assessment Report replaces these generalizations with specifics.

TYPICAL LEGACY PHP

One file per page, with routing implied by the filesystem and .htaccess rewrites.

/orders.php?id=42
/admin/edit_order.php
DJANGO EQUIVALENT

Explicit URL configuration mapped to views, versioned with the code.

path('orders/<int:pk>/', views.order_detail)
TRADE-OFFURL changes need redirect maps to protect existing links and SEO.

§4 QUESTIONS
Can our existing database be kept?[+]

Sometimes. Django can work with existing schemas; whether to keep, refactor or migrate the database is an Assessment finding, not an assumption.

Is the PHP code translated into Python?[+]

No. Behavior is re-implemented by engineers in idiomatic Django. Automated translation is not part of the service.

What if Django isn’t the right fit?[+]

The Report will say so. Talya Smart also works with Node.js/NestJS, Next.js and Astro, and recommends based on findings.

Have a PHP system that runs on data and rules?

Start with a conversation about what it does and who depends on it. We’ll explain how an Assessment would be scoped.
