About

my path.

📚 I initially stopped studying after completing a Technological Baccalaureate. From odd jobs to odd jobs, I quickly realized that this context would not be enough for me. So, at the age of 21, I decided to resume my studies and pursue a degree in e-commerce.

🏋️‍♂️ These studies allowed me to work as an SEO specialist for 6 years. This experience taught me about the functioning of the professional world, teamwork, the weight of responsibilities, as well as managing a back office and search engine optimization.

🍀 As a SEO specialist, working closely with developers sparked my interest in this highly technical field. Therefore, I enrolled in a 6-month bootcamp training program to acquire the fundamentals of web programming and coding. Following that, I continued my learning journey through an apprenticeship program, pursuing a degree in Web and Mobile Applications Integration/Development with a specialization in React and Node.js.

🍾 Since then, I have worked with several companies on complete integrations, provided assistance to deliver projects on time, made modifications, and added new features...

👷 Today, drawing strength from my journey, I master the intricacies of the Agile methodology, the principles of Clean Code, and CI/CD pipelines, ensuring optimal scalability and maintainability for each web application I develop. My diverse experience, spanning from SEO to programming, enables me to bring a unique perspective to every project.

🧘‍♂️ As a Web Developer since 2020, I thoroughly enjoy working with Nuxt & NextJs in an Agile environment, adhering to clean code principles, and implementing CI/CD pipelines. I take pleasure in transforming mockups of various styles into dynamic and interactive websites to enhance the user experience.
