ABOUT

Hello and welcome on my personal professional page.

My name is Sándor. I am an enthusiastic software engineer mostly skilled in server-side enterprise technologies and architectures, but I am interested in the modern client-side web frontend development too. I have several years of experience and strong skills in Java and JavaScript equally, including knowledge of  numerous server-side and client-side frameworks, such as Spring, Vaadin, Angular and React.

Primarily I am specialized in enterprise financial applications but I have experience in web mapping applications and modern GIS tecnologies too.
