Senior Salesforce Developer | Apex, LWC, Integrations & Automation Hello, I’m Oleh, a certified Salesforce Platform Developer with 7 years of experience building and supporting integration-heavy Salesforce applications. I specialize in Apex, Lightning Web Components, asynchronous processing, API integrations, and complex business automation. My background includes financial services, mortgage, telephony, e-signature, AI-powered workflows, and external data synchronization. My core expertise includes: • Apex, Triggers, Queueable, Batchable, Schedulable, and REST services • Lightning Web Components and Apex-backed custom interfaces • REST, SOAP, XML, OAuth 2.0, JWT, Named Credentials, and webhooks • Bulk-safe architecture, retries, logging, deduplication, and reconciliation • Salesforce security: sharing, CRUD/FLS, permission sets, and guest-user access • Apex unit tests, HTTP callout mocks, bulk testing, and LWC Jest • Flows, Process Builder migration, Experience Cloud, and managed packages I have integrated Salesforce with RingCentral, Five9, Dialpad, Retell AI, DocuSign, Adobe Sign, SendGrid, AWS, OpenAI, Encompass, LendingPad, MeridianLink, HubSpot, QuickBooks, and other platforms. One representative project involved processing call recordings through Salesforce and AWS, linking them to CRM records, and using AI services for transcription, data extraction, and summaries. The main challenges were authentication, async processing, large files, retries, duplicate events, and partial-failure recovery. I can help with Apex and LWC development, integrations, code reviews, refactoring, Flow automation, security audits, and integration troubleshooting. I focus on solutions that are reliable, maintainable, secure, and practical for the business.
