Sergey T.
Salesforce Developer
I help companies fix and scale Salesforce systems. Especially when integrations, automation, or data flows don’t work as expected. Over the past 15+ years, I’ve worked with startups, mid-size companies, and enterprises, turning Salesforce into a reliable system of operations, not just a CRM. Most of my work focuses on integrations, process automation, and cleaning up complex or underperforming setups. I’ve helped teams fix broken integrations between Salesforce and tools like HubSpot, NetSuite, and other APIs, clean up messy data after migrations, improve data integrity, and build scalable automation using Flows and Apex. I also work on optimizing lead routing, pipeline visibility, reporting, and connecting Salesforce with external systems. My core expertise includes Sales Cloud, Service Cloud, Experience Cloud, Marketing Cloud / Account Engagement (Pardot), CPQ, Nonprofit Cloud, Litify, AppExchange app development, integrations, automation, and data migration. From a technical perspective, I work with Apex, Lightning Web Components (LWC), Aura, Visualforce, Salesforce Flow (record-triggered and screen flows), Platform Events, REST/SOAP APIs, webhooks, data modeling, validation rules, and process automation. I have hands-on experience integrating Salesforce with platforms like HubSpot, NetSuite, SAP, Stripe, Twilio, DocuSign, PandaDoc, Celigo, Zapier/Make, FormAssembly, Formstack, WordPress, and OpenAI / ChatGPT. I focus on building systems that are stable, scalable, and actually used by teams, not overengineered solutions that break over time. If you’re dealing with a messy setup, broken sync, or need to build something reliable from scratch, happy to discuss.
