About me
The Birth of a Passion for Web Development
It all began on a sunny day filled with heavy rain. As usual, I launched a session of Dofus, a French online game developed by three passionate creators. For me, it was more than just a game — it was a spark.
The more I immersed myself in that world, the more curious I became: how does an online game work? How do interactions between the user and the server animate objects, open menus, or update the interface? That curiosity led me to explore the fundamentals of software development.
I first dove into the technologies used at the time, particularly Flash and ActionScript. Although complex at first glance, they helped me understand the foundations of digital interactivity. From there, my attention shifted to another fascinating world: web development.
Discovering HTML, CSS, and later JavaScript was a real breakthrough. With the help of a few tutorials, I quickly built my first web page. The logic and simplicity of these languages drew me in and made me want to learn more. I began studying through Site du Zéro, now known as OpenClassrooms, marking the beginning of a long journey into the world of web development.
At just 13 years old, I had found my passion: web development.
From Passion to a Career in Web Development
That passion for web development naturally led me to pursue a professional path in the field. After graduating high school, I enrolled in a Bachelor's degree in software development, where I strengthened my web programming skills through hands-on projects, company internships, and team collaboration.
During that program, I worked with industry tools like Jira and adopted agile methodologies such as SCRUM. I developed strong time management and project delivery habits. My interest quickly gravitated toward backend technologies, especially PHP and Symfony, while continuing to build on my frontend skills with HTML, CSS, and JavaScript.
I then pursued a Master’s degree in Software Development and Mobility, which allowed me to explore new areas like mobile development and artificial intelligence, and to deepen my knowledge in software architecture and project management. These experiences taught me that being a good web developer means more than just writing code — it also requires essential soft skills like communication, autonomy, and teamwork.
After earning my Master’s degree in 2021, I spent several years at Randstad Digital France as a PHP/Symfony/Infrastructure web developer, working on a wide range of demanding and technically challenging web projects.
