• Ensure maintenance of existing modules, resolving bugs and improving functionalities based on user needs.

• Integrate and manage relational databases (MySQL) to store and organize billing information.

• Implement solutions to ensure the security and integrity of sensitive data.

• Work closely with project management, design, and QA teams to understand application requirements and specifications.

• Participate in code reviews and agile planning meetings to ensure code quality and adherence to deadlines.

• Optimize application performance to efficiently handle a large volume of transactions and billing documents.

• Ensure application compliance with current security standards and tax regulations.

• Write and maintain technical documentation for developed modules, facilitating future maintenance and integration of new features.

• Creation of Dockerfiles to build custom images.

• Implementation of CI/CD pipelines with Docker to automate deployments.

Currently employed at ORANGE as a PHP/SYMFONY developer, I work in a team of two developers and a project manager. I primarily work on an Orange application called LECLAIR ENTREPRISE, which has 3 modules (LECLAIR Trafic, LECLAIR Commande, LECLAIR Fiche Fraude). This application detects fraud and aims to determine if an order placed in an agency is eligible for acceptance based on a set of scenarios designed to verify the identity of the customer placing the order. I have worked on all phases of the V-cycle, completely rewritten an application from CodeIgniter to PHP/Symfony, and written documentation for each evolution made on the three modules. The budget for the LECLAIR project is estimated at approximately €800K for the year 2023.

My daily tasks:

• I rely on the specifications written by the project manager to analyze client needs;

• Writing technical and functional specifications independently.

• I create the specifications in the absence of the project manager;

• Development of new features;

• Performing regression tests;

• Fixing any issues;

• Providing technical documentation and user guides;

• Incorporating evolutions and programming them if necessary.

• Implementation of several REST APIs.

• Complete rewrite of an application coded in PHP/CODEIGNITER to a purely PHP/SYMFONY 5 solution, and on the FRONT end, the TWIG template engine integrating Bootstrap for ergonomics and JAVASCRIPT to enhance the user experience.

• Automation of the creation of fraud files from fraudulent orders received by the application using Event Listener and Event Subscriber. Technical environment: PHP 7 · JavaScript · Bootstrap · FTP Software · Symfony 4 Framework · TWIG · Git Lab · MySQL
