Summary
I have experience working with corporate IT environments (500+
users) and small teams. I worked with the full infrastructure stack:
Linux servers, virtualization (Proxmox, VMware, Hyper-V), VPN,
firewalls, and access management (LDAP, FreeIPA, Google
Workspace). I automated routine tasks using Ansible and Python to
reduce manual work and make systems more stable. I also worked
with email outreach systems: set up and improved mailing processes
using Mailgun, SendGrid, and internal tools. Monitored deliverability,
built dashboards, and analyzed results. In addition, I handled
operational and financial tasks: budgeting, vendor payments, SaaS
and license management, and support for FOP and LLC accounting,
reporting, and compliance. I focus on keeping systems stable,
processes clear, and infrastructure manageable.
