my name is zulfikar from indonesia, i have 6 years experience in android development, 1 year in hybrid mobile development with react native, and familiar with design pattern in mobile development. i can be a backend developer too using java springboot or express in node.js, the only thing that i'm lacking of is UI and UX design skills, so if you already have your UX and UI design there won't be any problem for me to deliver my works on time
