Building practical systems in Brazil

Infrastructure · Security · Automation · Applied AI

I design reliable systems for infrastructure, security, and applied artificial intelligence.

I'm Diogo Wermann, an IT Infrastructure & Security Analyst focused on Windows automation, Microsoft Intune, hybrid identity, and the safe integration of AI into operations, documentation, and internal systems.

CURRENT FOCUS dw://portfolio

Operational and AI-assisted systems that remain safe under uncertainty.

Automation and agents should be observable, reversible, and explicit about the decisions they refuse to make.

Endpoints Intune → Windows Managed

WHAT I WORK ON

Infrastructure, security, and AI applied to real operational problems.

I operate across the layers where identity, endpoints, automation, knowledge, and business continuity meet.

01

Automation & Applied AI

Repeatable workflows and AI integrations for operations, documentation, and knowledge management, with permissions, validation, and human review.

02

Endpoint Management

Microsoft Intune packaging, deployment, detection, policy validation, and reliable device-side execution.

03

Hybrid Identity

Active Directory, Microsoft Entra ID, synchronization, device identity correlation, and access-aware operations.

04

Resilience & Observability

Backups, logs, dashboards, service health, recovery procedures, and evidence for operational decisions.

SELECTED PROJECTS

Public tools built from production problems.

Each project starts with an operational constraint and is designed around safety, maintainability, and clear documentation.

FEATURED CASE STUDY

An enterprise operations portal built around real internal workflows.

A private modular platform for support, assets, dashboards, scheduling, integrations, and an AI-ready knowledge base. The source remains private; its architecture and decisions can still be documented responsibly.

TECHNICAL WRITING

Detailed implementation notes, not generic tutorials.

Long-form articles explain the constraints, architecture, safeguards, and tradeoffs behind the systems I build.

ABOUT

Infrastructure, security, and applied AI with engineering discipline.

I work across infrastructure, support, automation, endpoints, observability, security, and applied AI. I turn operational knowledge into systems that are easier to understand, audit, and maintain.
