I develop applications, services, websites for business and government agencies. On working, I use the Mac Os distribution. I raise web servers based on deb packages, I use Ubuntu, Nginx, PHP-fpm, MySQL, Redis, and sometimes Elasticsearch. To view design layouts I use Avacode, Figma, in the layout I use the latest HTML5 specifications and preprocessors for styles, and I prefer to use Bootstrap as the main framework. If necessary, I use Bulma, Schema.org micro-layout, and Open Graph.
