About Me

Who I am

Website development is an exciting process for me. I enjoy developing new layouts and experimenting with different frameworks to see what is possible. In my spare time, you can find me taking photos of nature, rock climbing, or hanging at home playing some games.


My favorite CSS tool is CSS Grid due to its layout flexibility. I am currently focusing on JS's React framework. Efficiently creating websites using the Agile methodology from the ground up with HTML, CSS, JSON, and JavaScript, along with modern frameworks like React, Mustache, and Handlebars. Strong background in version control and ticket management tools such as Jira, Bitbucket, and SourceTree.
