Hello,
I am PHP and JAVA developer. Also, I am certified server's administrator and front-end developer. I have a bunch of webistes and web apps made in PHP, mostly in Symfony2/3, Wordpress and eZ Publish CMS (based on PHP), but web is not what you need right now.
I am good with ReactJS and React Native too and I have one mobile app, like food order with two synced part, admin app and users app.
Last 8 months I am working on Android apps and I can make what ever you want, just need good app specification.
I am very interested for this job and I think we should discuss the details...
Best regards,
Rados
