Analista de Infraestrutura de TI

Linux • Windows Server • Redes • Monitoramento • Automação • Trilha CloudOps/DevOps

Profissional de Infraestrutura de TI com experiência prática em suporte, servidores, redes, monitoramento, automação e documentação técnica.

Meu trabalho combina operações tradicionais de infraestrutura com scripting, containers, serviços self-hosted e IA local. Minha direção de carreira atual é CloudOps/DevOps, agregando nuvem pública, infraestrutura como código e CI/CD à base operacional que já uso em ambientes reais.

Experiência principal

Área Tecnologias e práticas
Sistemas Linux, Debian, Ubuntu, Windows Server, Active Directory, Group Policy
Redes TCP/IP, DNS, DHCP, switching, troubleshooting, SSH, VNC
Monitoramento Zabbix, Grafana, logs, alertas e investigação de incidentes
ITSM e inventário GLPI e OCS Inventory
Automação Bash, PowerShell, Python, REST APIs e webhooks
Containers e virtualização Docker, Docker Compose, XCP-ng e serviços self-hosted
IA aplicada Ollama, Open WebUI, modelos locais, experimentos com RAG e ambientes offline-first

Projetos em destaque

Migração Kubuntu — 300+ estações — Liderei a migração de mais de 300 estações de trabalho para Kubuntu integrado ao Active Directory: implantação em massa por imagem clonada (Rescuezilla), GPO no Linux com CID e scripts Bash para hostname único por VLAN, antivírus, atualizações via mirror apt interno e impressoras via CUPS. Documentação Stack: Kubuntu, Active Directory, CID, Rescuezilla, Bash, DHCP/VLAN, apt mirror e CUPS

Sistema de Selos Veiculares — Aplicação Django para gestão de pessoas, veículos e selos de identificação, com QR Code/PDF, ocorrências, painel operacional e integração LPR/ANPR.
