Profile

Technical Support Engineer specialising in DNS infrastructure, domain lifecycle management, and platform-level incident resolution.

At Team Internet Group, I troubleshoot domain registration, transfer, and renewal workflows, diagnose DNS misconfigurations (A, CNAME, MX, TXT), and investigate propagation issues using tools like dig and nslookup. I analyse API and system logs, support VIP customers with escalated cases, assist with domain abuse investigations, and collaborate with engineering teams on platform bugs - working with registrar/registry protocols including EPP concepts and domain states.

I am pursuing an MA: IT Cyber Security at Maria Curie-Skłodowska University, bridging hands-on support with advanced system defense studies.
