How I learned Salesforce
Salesforce is the best in cloud computing.
I have been working as a professional developer in Salesforce with integration, Apex, Visualforce Pages, Lightning Component, custom Buttons, all types of automation process (workflows, process builder, lightning flows, validation rules), set up new org, migration, etc.
I have written much code for integrating third-party APIs and websites with the best approaches for clients (from UK, USA, India). I never had one unsatisfied client because of my smart and hard work. I can write code as fast with the optimized code and query.
