The most practical path for how to become a Salesforce developer is to start with platform basics on Trailhead, then learn Apex programming, SOQL, and Lightning Web Components through hands-on practice in a free developer org. After that, earn the Salesforce Platform Developer I certification, build 2–3 real projects (triggers, LWC apps, integrations), and apply for internships or junior developer roles. Consistent hands-on practice matters more than just watching tutorials.

A Salesforce developer builds custom functionality on the Salesforce platform. This includes writing Apex classes and triggers, building user interfaces with Lightning Web Components and Aura, integrating Salesforce with external applications through APIs, writing SOQL queries, automating business processes, managing deployments, and fixing bugs. They work closely with admins and business teams to turn requirements into working solutions.

The Salesforce developer salary in India varies by experience and skill set. Freshers typically earn around ₹4–7 LPA, mid-level developers with 3–5 years of experience earn roughly ₹10–18 LPA, and senior developers with strong Apex, LWC, and integration skills can earn ₹20 LPA or more. Product-based companies and certified developers with hands-on project experience usually command higher packages.

To compete for Salesforce developer jobs as a fresher, focus on three things: a strong certification (Platform Developer I), a portfolio of hands-on projects such as trigger implementations and LWC applications, and solid interview preparation. Practicing scenario-based questions and doing mock interviews before applying significantly improves your chances, especially since most fresher interviews test practical problem-solving rather than theory.

Common Salesforce developer interview questions cover Apex basics (classes, triggers, governor limits), SOQL and SOSQL, asynchronous Apex (Batch, Queueable, Future), the order of execution, trigger design patterns, LWC lifecycle hooks and communication, integrations (REST/SOAP, Named Credentials), and security (profiles, permission sets, sharing rules). Freshers usually get definition-based questions, while experienced candidates face architecture and scenario-based problems.

To create a Salesforce developer account, go to the Developer Edition sign-up page on developer.salesforce.com, fill in your name, email, and role, then verify your email address. The Developer Edition org is completely free and gives you access to Apex, Lightning Web Components, APIs, and most platform features, making it ideal for learning and practice. It is not meant for production or customer data.

Apex triggers in Salesforce are pieces of Apex code that automatically execute before or after database events like insert, update, delete, and undelete on a record. They are used to automate complex logic that declarative tools like Flow or validation rules cannot handle, such as updating related records, enforcing custom business rules, or syncing data across objects. Before triggers are used to validate or modify the same record, while after triggers are used for operations on related records.

Frequently asked topics include the difference between before and after triggers, Trigger.new vs Trigger.old, bulkification, governor limits, handling recursive triggers, and the order of execution. Interviewers rely heavily on Apex triggers scenario based questions, such as updating a parent record when a child is created, preventing duplicate records, or calculating rollups without formula fields, so practicing real scenarios is essential.

The core Apex triggers best practices are: write one trigger per object, keep zero logic inside the trigger and delegate it to a handler class, bulkify your code to handle up to 200 records at once, avoid SOQL queries and DML statements inside loops, use context variables correctly, and prevent recursion using static Boolean flags. Following these practices helps you avoid governor limit errors and keeps your code maintainable.

An Apex trigger framework is a structured design approach for organizing trigger logic in a scalable way. Instead of writing logic directly inside triggers, a framework routes trigger events to dedicated handler classes, enforces the one-trigger-per-object rule, controls execution order, manages recursion, and allows triggers to be bypassed when needed. Frameworks become essential in large orgs where multiple triggers on the same object cause unpredictable behavior.

The Apex trigger handler pattern is a design pattern where the trigger contains only a single dispatch line, and all the actual logic moves into a separate Apex handler class. This makes the code cleaner, easier to unit test, and easier to control — for example, you can stop recursion with a static variable or bypass logic during data loads. It is the foundation of most trigger frameworks and a favorite interview topic for experienced developers.

Salesforce does not allow you to edit Apex code directly in production. To deactivate an Apex trigger in production, you must deploy a new version of the trigger with the "Active" checkbox unchecked, using a change set, SFDX/VS Code, or a CI/CD pipeline. The recommended approach is to deactivate rather than delete the trigger, so you keep the code available for rollback, and always test the change in a sandbox first.

Lightning Web Components (LWC) is Salesforce's modern UI framework built on standard web technologies like HTML, JavaScript, and Web Components. It is lighter and faster than the older Aura framework. Developers use LWC to build custom user interfaces, fetch data from Apex using @wire or imperative calls, and manage component behavior with lifecycle hooks such as connectedCallback and renderedCallback. Most new Salesforce UI development is now done in LWC.

To debug Lightning Web Components, enable Debug Mode in your Salesforce org so the browser loads unminified code, then use Chrome DevTools along with the Salesforce Lightning Inspector extension. You can add console.log statements, set JavaScript breakpoints, inspect the component tree, and check state and events. For server-side issues, review the Apex debug logs for the methods your LWC is calling.

The most asked Lightning Web Components interview questions focus on lifecycle hooks and their order of execution, communication between components (parent-to-child via public @api properties, child-to-parent via CustomEvent, and Lightning Message Service for cross-DOM communication), the difference between @wire and imperative Apex calls, reactivity, and when to choose LWC over Aura. Many interviews also include a small hands-on LWC coding task, so building sample components beforehand helps.
