Hey, since a long time i was writing web apps using classic languages (PHP, and some .Net and Java). I tried to industrialize PHP development trhought my different Jobs. But in fact i was wrong, the truth is on JS side ;-) So i played with MeteorJS, then i worked with VueJS and now Angular2+

A bit of devops (but not so much) and finaly i can help you to build complex app with queuing, workflows, NoSQL or/and SQL Databases.
