Overview

This skill provides expert guidance for developing enterprise-grade solutions on the Salesforce platform. It targets Apex development, Lightning Web Components, SOQL optimization, integrations, and CI/CD using Salesforce DX. Use it to design scalable, bulkified code and to stay within platform governor limits while meeting business requirements.

How this skill works

I analyze requirements, recommend a declarative vs programmatic approach, and produce concrete artifacts: Apex classes, trigger handlers, LWC files, optimized SOQL, and test classes. I enforce platform constraints—bulkification, governor limits, field-level security, and >=90% test coverage—and propose async patterns (Batch, Queueable) and integration designs. I also outline deployment steps using Salesforce DX and CI/CD best practices.

When to use it

• Building custom Apex classes, triggers, or async jobs for bulk data processing
• Developing Lightning Web Components with proper encapsulation and events
• Optimizing SOQL/SOSL queries and relationships to avoid limits and improve performance
• Designing integrations via REST/SOAP, platform events, or external services
• Setting up Salesforce DX, scratch org workflows, and CI/CD pipelines

Best practices

• Always bulkify Apex and avoid SOQL/DML inside loops
• Write comprehensive test classes covering positive, negative, and bulk scenarios (>=90% coverage)
• Use selective SOQL filters, indexed fields, and relationship queries to reduce cost
• Respect sharing, field-level security, and avoid hard-coded IDs/credentials
• Choose async processing for long-running or large-volume operations (Batch, Queueable, Platform Events)
• Use Salesforce DX and source-driven deployments with automated tests and code review

Example use cases

• Implement a trigger handler that bulk processes related records and enqueues a Queueable job for heavy work
• Create a Lightning Web Component that displays related lists using wire adapters and custom events
• Optimize a slow report query by replacing non-selective WHERE clauses with indexed filters and selective parent-to-child queries
• Design a platform event flow to decouple an external system from internal processing and guarantee retries
• Set up a CI pipeline that validates metadata deployments to scratch orgs and runs Apex tests before production deploys
