Hi, I am Paraskevas Leivadaros

System Engineer / Web Developer

I am a highly skilled System Engineer with experience working on Red Hat Enterprise Linux Servers. I am currently studying for the Google Cloud Certified Associate Engineer exam to further expand my knowledge in cloud computing. I have a strong background in technologies such as RHEL, SoapUI, JMeter, Grafana, Postman, Prometheus, VMWare ESXi, and Oracle Database.

I have extensive experience in website design, development, and maintenance. I currently maintain 4 WordPress websites where I handle everything from server setup to website design, development (using PHP, CSS & JS), content writing, HTTPS security, email and newsletter campaigns.

With my combination of technical skills and website development experience, I am well-equipped to handle any project that comes my way. I am constantly seeking to learn new technologies and stay up-to-date with industry developments.
