@charlescharalambous

Support Engineer at n8n who designed a workflow that identified over 5,800 duplicate tickets in seven months.

At n8n, I support customers across Cloud and self-hosted deployments, investigating workflow, API integration, webhook, credential and execution issues. I handle approximately 250–350 customer replies and close 150+ tickets per week.

I independently designed a duplicate-ticket detection workflow that identified more than 5,800 duplicates over seven months. I also collaborated on four automations for payment-provider-resolvable cases, removing more than 160 tickets from the Support queue in the first month.

At Hyve Group, I provided first- and second-line IT support across a global workforce of 550+ users and achieved a 98% positive ticket-feedback rating. My work included account administration, device preparation and access support.

Earlier, at Conisbee, I led a five-month SCCM project and packaged and tested more than 130 applications. Across my IT support roles, I’ve also worked with VMware, Microsoft systems, endpoint security and user-facing troubleshooting.
