We have 2 basic 'divisions' in our offices among the developers:
This is the major split. We house people who are strong in fullstack, or just sided into one of the backend technologies above, but we all gladly mix into node.js, there we make peace.
We of course do the front technologies, where we house experts doing 'only' highest quality HTML with finely crafted SEO through schema.org. We do CSS only through SCSS, and we compile in webpack or gulp.
Our industry experts are committed to excellence, teamwork and contributing to the technology ecosystem no matter the above mentioned 'splits'. We value collaboration and next-generation software methodologies to build software.
