Front-end: everything involved with what you see in the browser.
Back-end or the “server-side”, is how your site works, updates, and changes. This refers to everything you can’t see in the browser, like databases and servers. Here we mostly worry about security, structure, and content management.
Testing & Delivery: first, we check your website for functionality, usability, security, compatibility, performance before it’s made live and accessible to the public. Only then very carefully we push changes or updates from one environment to another ending up in the live.
Maintenance: Backups, updates and security – so the content remains current.
