Modern Web Applications Infrastructure

You'll get to know how to manage project features and improve quality in your web projects.

What tools, platforms and services will be useful on each step of your application development lifecycle and what benefits can you get using them. Keep your project production ready. Release often, release stable.
Get reactive feedback about your project status: detect issues and address them fast. Continuous improvement process: stability, performance, and maintainability, modern delivery and distribution approaches. Let’s try to uncover some production-proofed practices how to improve code-base quality and project stability itself.

History rewrite EASY BRANCHING AND MERGING You can work alone or with a team. You can work with or without central server. Even without network connection.
