Vadim Aland — IT Specialist, Digidoktor OÜ

Networks & Infrastructure

Multi-vendor networks (Fortinet, MikroTik, UniFi), Windows Server & Linux administration and Hyper-V virtualisation — designed, built and documented for predictable performance and clean handover.

Cloud & Identity

Microsoft 365, Entra ID (Azure AD) and Active Directory — secure identity, access and collaboration across your organisation.

Reliability & 24/7 Operations

Monitoring (Zabbix), backup & disaster recovery (Synology, QNAP) and proactive maintenance — built for uptime-critical environments.

What I Do

End-to-end IT for environments that can't afford downtime — from networks and servers to cloud, continuity and automation. Working languages: English, Estonian, Russian.

  • Network & Infrastructure

    Multi-vendor networks — firewalls, VLANs, VPN and Wi-Fi, switching and routing. Designed, deployed and documented from the ground up.

  • Servers & Virtualisation

    Windows Server administration (Active Directory, Group Policy) and Linux servers on Hyper-V — builds, migrations, hardening and monitoring for environments that run around the clock.

  • Microsoft 365 & Cloud

    Microsoft 365, Entra ID and Intune deployments and migrations — secure identity, MFA and endpoint management.

  • Backup, DR & Continuity

    3-2-1 backup (Synology Active Backup), disaster-recovery planning and monitoring (Zabbix, Grafana) for uptime-critical operations.

  • Surveillance, Access Control & VoIP

    Design, deployment and administration of building security and communication systems — IP video surveillance (Milestone, Mirasys, Hikvision), access control (Protege, FoxSec) and IP telephony (3CX).

  • Monitoring & Automation

    Observability and centralised logging, CMDB/IPAM (NetBox), and Python / PowerShell automation and internal tools.

  • AI Solutions & Automation

    Practical AI for your operations — LLM-powered Telegram bots and assistants, workflow automation and API integrations, with local/offline models (Ollama) where data must stay on-site. Human-in-the-loop safeguards, delivered faster with AI-assisted development.

  • IT Audit & Consulting

    Infrastructure audits, risk assessment and pragmatic, prioritised modernisation roadmaps.

  • IT Procurement & Asset Lifecycle

    Company-wide purchasing of IT hardware, licences and subscriptions, with full asset lifecycle management — commissioning, renewals and decommissioning, disposal or resale.

Selected Projects

A selection of IT infrastructure, automation and software projects from the past few years.
