At Sumsub, I served as the primary technical contact for B2B clients, resolving integration issues across complex identity verification workflows.
I managed incident lifecycles through Intercom and Slack, investigated verification errors in system logs, and escalated high-priority bugs with diagnostic reports. I also contributed troubleshooting playbooks that reduced handling time for common incidents.
At B2Broker, I provided technical troubleshooting and end-to-end ticket management for corporate clients using Jira and Zendesk. My work also included hardware and software maintenance and workstation setups.
At Like Centre (Moscow), I administered Bitrix24, AmoCRM, and Mailcow systems and automated processes using Smart Processes. Earlier, at Klondike Group, LLC, I supported users, maintained workstations, and provided technical support for live events.
