Senior Software Engineer, NodeJS, PHP, Symfony & Backend   (Send me a message on LinkedIn)

I take great pride in presenting myself as a highly motivated Senior Software Engineer with a strong dedication to leveraging cutting-edge technologies. Furthermore, I possess extensive expertise in the administration of operating systems, acquired through my extensive background in both Microsoft Windows and GNU/Linux distributions (specifically CentOS and Debian), wherein I have successfully delivered internet services to a diverse clientele comprising hundreds of users and millions of visitors.

My commitment to continuous learning is unwavering, and I am inherently self-directed in my pursuit of knowledge. I consistently seek to acquire new skills and stay abreast of developments, whether in emerging frameworks, programming languages, or operating systems.
