What Does a Salesforce Developer Actually Do?

Imagine a company struggling to track its leads manually in Excel, wasting time and losing potential customers.
A Salesforce Developer steps in and builds a customized app that helps them:

• Manage leads

• Automate follow-ups

• Track performance

all in one place.

That’s the power of Salesforce development: solving real business problems through smart, customized apps.

Tools Salesforce Developers Use to Build Apps

To understand how they do it, let’s look at the key tools and platforms:

• Salesforce Developer Console – Built-in code editor for writing Apex, debugging, and testing

• Salesforce Lightning App Builder – Drag-and-drop tool to create apps visually

• Apex – Salesforce’s backend programming language (similar to Java)

• Visualforce – Used to create custom UI pages

• Lightning Web Components (LWC) – Modern, fast, flexible UI components

• Trailhead – Salesforce’s free learning platform for hands-on practice

Step 1: Creating a Developer Org (Your Playground)

To start building apps, developers sign up on developer.salesforce.com login and create a developer org — a free Salesforce environment for testing, experimenting, and building apps.

It’s like having your own mini-business setup where you can explore ideas without affecting real systems.

Step 2: Understanding App Requirements

Before writing any code, Salesforce developers talk to stakeholders to understand the business needs.

For example:

• A hospital needs an app to manage patient history

• A travel agency needs a booking management system

• A retail company wants to track inventory and customer orders

Developers ask the why, what, and how before they begin building.

Step 3: Building Using Clicks (No-Code / Low-Code Approach)

Salesforce development is not always about deep coding. Developers can build apps using point-and-click tools like:

• Object Manager – Create data tables (Leads, Customers, Orders)

• Lightning App Builder – Design user-friendly screens with drag-and-drop components

• Process Builder & Flow – Automate tasks like email alerts, approvals, and notifications

This makes Salesforce a powerful platform for developers and non-coders alike.

Step 4: Adding Custom Logic Using Apex & LWC

When business needs get more advanced, developers use Apex and LWC.

Apex (backend logic) helps with tasks like:

• Auto-assigning leads to sales reps

• Triggering events when data changes

• Connecting Salesforce with external systems like WhatsApp or Gmail

Lightning Web Components (LWC) create:

• Modern, responsive, lightning-fast user interfaces

• Custom dashboards, forms, calculators, and more

Step 5: Integrations Connecting Salesforce with Other Systems

Businesses use multiple tools WhatsApp, Gmail, ERPs, websites, payment gateways.
Salesforce developers use APIs and integrations to connect these platforms with Salesforce.

This makes apps more powerful, automated, and data rich.

Step 6: Testing and Deployment

Before launching an app or feature, developers test it thoroughly:

• Debugging using Developer Console

• Creating Test Classes in Apex

• Fixing errors and improving performance

Once everything works smoothly, they deploy it to production using Change Sets or modern DevOps tools.

Step 7: Training Users and Updating the App

After deployment, developers train end-users (sales reps, support agents, etc.) to use the new app features.

And the work doesn’t stop their apps need:

• Updates

• Improvements

• New features

• Fixes

Salesforce Developers constantly enhance systems as businesses grow.
