A Salesforce developer must have a combination of technical and soft skills to become successful. Gaining Salesforce proficiency and becoming an expert in Apex and JavaScript enables you to customize and extend the functionality of Salesforce. Effective development requires an understanding of data modelling, database concepts, and Salesforce data structures.
Furthermore, a solid understanding of Salesforce's declarative features, such as Process Builder and Lightning App Builder, is necessary. Building user interfaces and integrating external systems require knowledge of web technologies, including HTML, CSS, and RESTful APIs.
To ensure strong and scalable solutions, a deep understanding of Salesforce development best practices, security, and governance is essential. For career advancement in this field, it’s also advised to keep up with Salesforce releases and certifications such as the Salesforce Certified Platform Developer.
