What he does

Builds corporate infrastructure from scratch and keeps it running for years, automates operations, and puts AI agents into production. Started in user support and sysadmin work at an MSP, grew into a full-stack systems architect — from bare metal and networking up to LLM-driven workflows.

Expertise

• Systems, identity and mail — VMware ESXi, vCenter, Proxmox, Veeam, MS Exchange with DAG, Active Directory (AD DS / AD CS / AD FS), Windows Server, RDS + FSLogix, Keycloak, Zabbix.
• Networking and security — MikroTik RouterOS, Ubiquiti, pfSense, OPNsense, WireGuard, OpenVPN, IPSec, OSPF, GRE, angie, nginx, HAProxy, CrowdSec, Wazuh.
• Cloud and automation — Yandex Cloud, VK Cloud, Selectel, AWS, GCP, Azure, Terraform, Ansible, Docker, GitLab CI, Python, PowerShell, Bash, Ruby.
• AI agents — OpenAI, Anthropic, Model Context Protocol (MCP), RAG, vector databases, LangChain, agentic workflows.

Notable work

• Corporate infrastructure built from scratch, turnkey — 4 sites across 2 countries, 100–200 users, 50+ servers. Active Directory, Exchange with DAG between sites, mail pipeline on Proxmox Mail Gateway + HAProxy with SNI routing, multi-site routing on WireGuard + GRE + OSPF via FRRouting, MikroTik RouterOS 7, and an ACME → Exchange certificate automation pipeline. Delivered solo, end to end.
• 2FA and SSO for corporate mail — a custom Keycloak based 2FA provider, with ANGIE in front of OWA and Outlook clients handling SSO at the web-server layer. No changes to Exchange internals. Running in production, carrying all corporate mail traffic.
• Realtime voice agent on a cloud PBX — an LLM talks to customers live over SIP telephony, pulls answers from a knowledge base via RAG and escalates to a human on ambiguity. Not post-call analysis of recordings. Source: asterisk_to_openai_rt (Asterisk ARI + ExternalMedia, RTP, μ-law ↔ PCM resampling, VAD coordination, OpenAI Realtime API).
• Active Directory modernization — Windows Server 2008 → 2022, three sites, multi-site replication, several domains merged into one.
• GPO and ACL audit at scale — 17 PowerShell scripts to detect broken policies, restore Security Filtering after a mass downgrade to Authenticated Users, and clean stale NetLogon ACEs through pre-flight checks and a phased rollout. Every change with a backup and rollback path, across hundreds of GPOs.
• Multi-agent development workflow — three specialised AI agents (strategy, knowledge base, in-IDE developer) communicating through an MCP Memory Server and a shared knowledge layer.
• Office-to-datacenter networking — site-to-site IPSec across offices and two datacenters, redundant links, internet connectivity cost reduced by roughly 66%.

Availability

Open to Infrastructure Architect, Solutions Architect and Head of Infrastructure roles. Remote, full-time or long-term contract. Also works with Chinese technology companies entering the Russian market: local deployment, data-residency compliance (152-ФЗ) and cross-border infrastructure integration.
