Develop Advanced Salesforce Solutions

Provides expert patterns for Salesforce platform development spanning Lightning Web Components (LWC), Apex triggers and classes, REST and Bulk APIs, Connected Apps, and Salesforce DX with scratch orgs and 2nd-generation packages (2GP).

Use this skill when building LWC components with reactive data binding, writing bulkified Apex triggers, offloading work to async Queueable Apex, integrating external systems via Connected Apps and REST/Bulk APIs, or setting up Salesforce DX scratch-org and 2GP packaging workflows. Not a fit for external API integration beyond Salesforce (routes to a backend skill), complex custom UI beyond LWC (routes to a frontend skill), or HubSpot/data-warehouse/payment/auth integrations, which have their own dedicated skills.

Demonstrates the @wire decorator pattern for reactive LWC data binding against Lightning Data Service (getRecord) or Apex methods (@AuraEnabled(cacheable=true)), a bulkified Apex trigger using a handler-pattern base class with recursion prevention and single-DML bulk operations, Queueable Apex for async processing with retry-with-backoff and error-record logging (limited to 50 jobs per transaction), a Connected App JWT Bearer flow client for server-to-server REST API authentication and querying, and a Bulk API 2.0 client that creates a job, uploads CSV data, closes the job, and polls for completion - intended for 10K+ record operations.

Covers Salesforce DX scratch-org workflows (sf org create scratch, deploy, assign permset, import data, run tests) and 2nd-generation package development (sf package create/version create/version promote, requiring 75% code coverage to promote), plus a GitHub Actions CI/CD pipeline that authenticates the Dev Hub, spins up a scratch org, deploys, runs tests, and tears down the org.

Documents nine "sharp edges" by severity (governor limits apply per transaction not per record; @wire results are cached and can go stale; trigger recursion causes infinite loops; dynamic SOQL is vulnerable to injection; scratch orgs expire and lose data) and ten validation checks with exact error messages, covering SOQL/DML-in-loop governor limit violations, callouts from synchronous triggers, SOQL injection via string concatenation, missing WITH SECURITY_ENFORCED, hardcoded Salesforce IDs and credentials, and direct DOM manipulation in LWC's shadow DOM.

Built on the Salesforce platform stack: Lightning Web Components and Lightning Data Service, Apex (triggers, Queueable, AuraEnabled methods), REST and Bulk API 2.0 with OAuth 2.0 JWT Bearer or Web Server flow via Connected Apps and Named Credentials, and Salesforce DX/CLI for scratch orgs, 2GP packaging, and GitHub Actions CI/CD.

Salesforce developers building LWC UIs, Apex automation, external integrations, or CI/CD pipelines who need bulkification, governor-limit-safe patterns, and DX-based packaging rather than ad hoc, non-bulkified Apex.
