IT Operations Specialist at Florence Healthcare automating SaaS administration with n8n workflows that save about 8 hours a week.

Serbia
Message

At Florence Healthcare, I administer Google Workspace for about 250 users and own onboarding and offboarding, including account provisioning, access changes, and licence management. I also troubleshoot SSO and MFA issues and respond to compromised accounts and reported phishing incidents.

I built n8n workflows that connect internal SaaS tools through REST APIs, saving about 8 hours of manual administration a week. I resolve 40–60 tickets a week in Jira and maintain the knowledge base and runbooks in Confluence.

Previously, at Portfolio BI, I operated Azure and on-premises infrastructure for financial-services clients across multiple regions, with 24/7 coverage. My work there included Microsoft 365, Active Directory and Entra ID administration, PowerShell automation, and backup and disaster-recovery procedures.
