I have worked for a national Australia Financial Investment company for 6 years. My job was to create, deploy, maintain and continue to develop upon their Salesforce system.
In my 6+ years, I feel I have mastered every avenue of the Salesforce platform. Including but not limited to: Emailing tools, automatic processes, Integrations with legacy third party systems, integrations with current third party APIs and integrations with in house built C# web applications.
Although, I do not have specific knowledge with PHP, I am an immensely quick learner and feel that nothing is outside my ability to learn and master. Although I have not experience with PHP, my work with apex has allowed me to pickup other languages such javascript, c#,python, etc with ease.
I have extensive knowledge with the salesforce platform. I know its strengths and limitations. I have dealt with just about every salesforce error, problem, bug, governor limit you can think of.
I am confident that any task or tool that you would hope to implement, I would be able to use the structure of a similar project I have done in this past, this will save development time.
A few Salesforce skills you might be interested include:
Integrating with external systems
Decoding emails and performing actions (creating cases, tasks,etc)
Outlining company workflow within the salesforce platform
Email to Client Tools (automatic emails, email apps, etc)
Custom, responsive Record List viewing
Happy to show examples of my work
