My Projects:
- Set up virtual servers from scratch and migrated physical servers to virtual ones using Hetzner hosting. Reorganized the 1C server structure. Prepared terminal servers for users, which distributed the load and eliminated slow performance of 1C databases and other software. Ensured security, uninterrupted operation, data backups, and network security.
- Organized IP telephony on the 3CX platform, enabling internal communication over the internet independent of mobile operators. Supported SIP numbers for nationwide calls and incoming calls from external sources. (in 2 different companies)
- Replaced the email web hosting service with Zimbra on a Linux server, enabling the company to have its own independent mail service. Simplified mail administration and eliminated monthly expenses for mail server rental and mailbox space.
- Fully automated the network servers: implemented backup creation, remote copying of information to NAS file servers, and automatic updates of the accounting software. This ensured that the accounting department could be confident that the information from the databases would always be up-to-date, preserved, and secure.
- Implemented dynamic routing to distribute network load and ensure stable packet routing, accommodating high traffic and necessary nuances.
