Linux System Administrator & Network Engineer · Deutschland
OpenWrt multi-WAN, IPv6 architecture, VPN/tunneling, SSH3/QUIC, MCP tooling, and automation for production routers.
- Multi-WAN / failover — mwan3 policy routing, health checks, IPv6 over WireGuard and tunnel brokers
- IPv6 — NPTv6, prefix delegation, split-default routing, HE/6in4 integration
- OpenWrt — custom packages, LuCI extensions, opkg/apk builds, prod/dev lab workflows
- SSH3 / QUIC — HTTP/3-based remote shell: upstream Go forks (
ssh3-go,quic-go), SSH3 transports in tooling - MCP tooling — unified SSH MCP server with a host registry (direct, SSH3/QUIC and WSL-proxied transports)
- AI-assisted engineering (vibecoding) — agentic CLI workflows as a first-class dev process: repo rules & skills, plan → tests → code loops, multi-agent orchestration
- Local LLM stack — Ollama models and embeddings, agent memory (
echovault), custom MCP servers - Automation — Perl, Bash, Python, PowerShell; CI-friendly packaging and deploy scripts
20+ years of system administration and networking: ISP operations, high-load hosting on Nginx, VPN infrastructure, monitoring (Nagios, Grafana); FreeBSD/Linux administration, Perl/Mojolicious and Python development; the last decade — technical support engineering in fintech.

Инженер по Linux и сетям: OpenWrt, multi-WAN, IPv6, VPN, SSH3/QUIC, MCP-инструментарий и автоматизация. Рабочий процесс — вайбкодинг: агентские CLI-сценарии, правила и skills репозитория, мульти-агентная оркестрация; локальный LLM-стек (Ollama, embeddings) и память агентов (echovault).
20+ лет системного администрирования и сетей: ISP, high-load хостинг на Nginx, VPN-инфраструктура, FreeBSD/Linux, разработка на Perl/Mojolicious и Python; последнее десятилетие — support-инжиниринг в финтехе.
Основные открытые проекты — mwan3, mwan6-npt, ssh-hosts-mcp, luci-app-netbird и связанные LuCI-пакеты для продакшен-роутеров с несколькими туннелями.
