Yii2 Backend Developer (Migration of the project from PHP 7.2 to PHP 8.1)
About the project:
Chess project in the process of infrastructure modernization. We are working alongside the Lead Developer.
Current state:
PHP 7.2 (but there is legacy code from PHP 5.5).
Yii 2.0.13 (Advanced template).
Architecture: separated Backend (API) and Frontend (React).
Database: MySQL 5.7 (preparing for migration).
Task:
Carefully migrate the backend while preserving the functionality of the business logic.
Goal: Achieve stable code on PHP 8.1 + Yii 2.0.53
Work plan (Phased):
Preparation: Adaptation of the code for PHP 7.4. Fixing Deprecated warnings, cleaning dependencies in composer.json.
Framework update: Updating the Yii2 core from version 2.0.13 to 2.0.53. This is the most critical stage (fixing incompatibilities in internal components and third-party extensions).
Final: Upgrading to PHP 8.1. Final debugging, typing, fixing critical errors of the new version of the language.
What we expect from the candidate:
Migration experience: You have already migrated old projects to new frameworks and know what "Dependency Hell" in Composer means.
Deep knowledge of Yii2: You understand what has changed in the framework over the past 5 years and know how to make old behaviors/widgets work with new versions.
Ability to work with Legacy: You are not intimidated by code written 8-10 years ago (the project originally started on PHP 5.5).
Attention to detail: Ability to work with Git, understanding that each change can affect critical calculation logic.
We offer:
Clearly defined tasks and plan (we already have a migration strategy ready).
Dedicated testing environment (new VM on Ubuntu 22.04).
Support from the current team (Lead Developer and Junior, who is writing API tests for backup).
