With regards to the universe of Salesforce, the sky’s the limit. There isn’t a field that can’t be added by your Salesforce administrator nor any code a Salesforce developer can’t execute.

• A Salesforce administrator is someone who manages and administers a production Salesforce organization. Admins usually carry out minor declarative changes and have the responsibility of managing releases into production.
• A developer would typically build functionality including Apex/Visualforce in a sandbox before handing it over to the administrator to schedule deployment.

Shared responsibilities

A Salesforce administrator helps to manage ongoing system developments by communicating with customers and colleagues regarding new developments, support etc. They provide continued support to colleagues, especially Salesforce developers, and clients.
Ongoing documentation throughout the development can be communicated to the Salesforce admin so that they are prepared for any customer interaction/support issues.
Bug fixing will likewise happen to guarantee a smooth release to clients. This is a great time to involve the Salesforce admin so that they can test usability and provide feedback.
More and more admins are coding and are taking on some of the responsibilities that would otherwise be left to a developer. However, it is important to understand that though admins and devs have their own roles, there really are no boundaries when it comes to the capabilities of Salesforce admins.
