Senior Python + PHP Developer

• Team Role: BackEnd Developer
• Tech stack: PHP, Python
• Grade: Senior
• Experience (in years): 5+
• Allocation: Full-time
• Project: This project involves migrating a legacy PHP web application to a modern Python stack. The objective is to re-write the backend, optimizing performance, scalability, and maintainability. The new system will leverage FastAPI for fast, asynchronous APIs, SQLAlchemy for ORM, and a relational database (PostgreSQL or MySQL). Key tasks include analyzing the legacy code, redesigning the backend architecture, migrating the database, rebuilding APIs, and ensuring smooth integration with the frontend, all while ensuring seamless deployment and testing.

!!!You will work in an international team, so knowledge of English B2 or above is necessary.

Tasks on the project
Legacy Code Analysis
: Review and understand the existing PHP codebase to identify key functionalities, dependencies, and architecture that need to be migrated to Python.
Backend Architecture Design
: Plan and design the new Python backend architecture, ensuring it aligns with modern practices and scalability requirements.
Database Migration
: Map the existing database schema and data from the PHP application to the new system, ensuring compatibility with the chosen Python stack (SQLAlchemy with PostgreSQL/MySQL).
API Development
: Rebuild the application's APIs using
FastAPI
, focusing on performance optimization, security, and best practices for asynchronous communication.
Unit Testing and Debugging
: Develop unit tests to ensure the new Python backend functions as expected and debug any issues during the migration process.
Performance Optimization
: Ensure the Python implementation provides equal or improved performance compared to the legacy PHP system.
Deployment Setup
: Configure deployment pipelines, containerization (Docker), and ensure the backend runs smoothly in production.
Documentation
: Document the new backend architecture, API endpoints, and migration process to ensure maintainability and knowledge transfer.
Integration with Frontend
: Ensure seamless integration of the new backend with the frontend system, handling any necessary changes in data handling or API consumption.
Final Testing and Go Live
: Conduct thorough testing (including user acceptance testing) and prepare for a smooth transition from the old system to the new one.

This project focuses on transitioning a legacy PHP-based web application to a more modern Python-based architecture. The goal is to replace the outdated backend with a more efficient and scalable solution, utilizing FastAPI for building asynchronous APIs and SQLAlchemy for managing database interactions, with PostgreSQL or MySQL as the backend database.

Key tasks involve a comprehensive analysis of the existing PHP code, redesigning the backend architecture to align with modern standards, migrating the database, and re-implementing APIs. The project will also include testing, integration with the frontend, and ensuring smooth deployment to guarantee the new system operates seamlessly in production.
