What Does a Salesforce Developer Do?

28/08/2025

Ever wondered what does a Salesforce developer do when they’re not buried in code and clicking through endless configuration menus?

You’re not alone.

With Salesforce dominating the CRM landscape and businesses scrambling to implement custom solutions, the role of a Salesforce developer has become more crucial and mysterious than ever.

If you’ve been considering this career path or simply want to understand what these tech wizards actually get up to all day, you’ve come to the right place.

What Is a Salesforce Developer?

A Salesforce developer is essentially a digital architect who builds, customises, and maintains applications within the Salesforce ecosystem.

Think of them as the bridge between what businesses need and what Salesforce can deliver.

Unlike traditional software developers who work with various programming languages and platforms, Salesforce developers specialise in:

  • Apex (Salesforce’s proprietary programming language)
  • Lightning Web Components for modern user interfaces
  • Visualforce for custom page layouts
  • SOQL and SOSL for database queries

But here’s the thing being a Salesforce developer isn’t just about coding.

Core Responsibilities of a Salesforce Developer

1. Custom Application Development

Salesforce developers create bespoke applications that solve specific business problems.

Picture this: A company needs to track complex approval processes that standard Salesforce can’t handle.

Enter the developer, who builds a custom workflow application complete with:

  • Automated notifications
  • Multi-level approval chains
  • Real-time dashboards
  • Integration with external systems

2. Data Integration and Migration

One of the most critical aspects involves moving data between systems.

Salesforce developers design and implement:

  • APIs to connect Salesforce with other business applications
  • ETL processes for data transformation and loading
  • Data validation rules to maintain quality
  • Migration strategies for legacy system upgrades

3. Lightning Platform Development

Modern Salesforce development revolves around the Lightning Platform.

Developers create:

  • Custom Lightning components
  • Lightning apps for specific business functions
  • Mobile-responsive interfaces
  • Interactive dashboards and reports

4. Process Automation

This is where Salesforce developers truly shine.

They build automated workflows that handle repetitive tasks:

Before automation: Sales reps manually update opportunity stages, send follow-up emails, and create tasks for different team members.

After developer intervention: The system automatically progresses opportunities, triggers personalised email sequences, and assigns tasks based on predefined criteria.

The Day-to-Day Reality of a Salesforce Developer

Morning typically starts with checking system health and reviewing overnight batch processes.

Then it’s into the thick of development work:

  • 9:00 AM – 11:00 AM: Code review and debugging session for yesterday’s deployment.
  • 11:00 AM – 1:00 PM: Building a custom Lightning component for the sales team’s new lead qualification process.
