Professional Summary

I am an IT professional with 8 years of experience in Technology Infrastructure, working in complex and heterogeneous corporate environments. I have proven expertise in both on-premises and cloud solutions, including virtualization with Hyper-V, Microsoft Azure platform, and Microsoft 365, with emphasis on Exchange Online, Azure Active Directory, and Azure Single Sign-On.

Currently, I serve as a Security Architect at Stefanini (since January 2022), where I am responsible for administering, maintaining, and evolving a hybrid environment, ensuring availability, security, and performance of the platforms under my management.

I possess solid skills in environment standardization, technical architecture definition, and implementation of market best practices (such as ITIL and information security). I also work with process automation and administrative routines using PowerShell, promoting operational efficiency gains.

I am a committed, analytical, and results-oriented professional who adapts easily to different scenarios and collaborates effectively with multidisciplinary teams. I constantly seek challenges that enable both technical and strategic growth, contributing to innovation, stability, and security of IT infrastructures in the organizations where I work.

Key Projects and Achievements

EMBRAER Project – Device Delivery Modernization with Zero Touch Deployment

I led the optimization of machine delivery processes for new employees and equipment replacements. The company faced challenges with the slow traditional image cloning process performed by the Field Service team. I designed and implemented a solution based on Microsoft Intune and Windows Autopilot, integrating Microsoft 365, Microsoft Purview, and DLP policies. Device delivery time was reduced to under 2 hours, with all corporate applications, configurations, and security policies automatically applied following the Zero Trust security model.

My responsibilities included:

Registering devices in Autopilot

Creating deployment profiles and compliance policies in Intune

Applying data protection policies via Microsoft Purview (DLP)

Integrating with Azure AD and conditional authentication

Ensuring BitLocker encryption and enabling Microsoft Defender for Endpoint

SOMPO Seguros Project – Data Leakage Prevention with Microsoft Purview

I was responsible for implementing a sensitive data protection strategy focused on Data Loss Prevention (DLP) and endpoint security. The core requirement was to monitor, identify, and prevent leakage of confidential information such as client data and strategic documents.

My activities included:

Mapping and classifying sensitive data with Microsoft Purview Information Protection

Creating and publishing DLP policies for email, SharePoint, OneDrive, and local devices

Integrating with Microsoft Defender for Endpoint to apply corrective measures and automated alerts

Training the client's security team for ongoing solution management

Generating reports and performing fine-tuning based on user behavior analysis

Globo Project – Mobile Device Management with Microsoft Intune

I worked on the assessment, standardization, and management of corporate mobile devices focusing on security and compliance. The client's challenge was the lack of centralized control over smartphones and tablets used by employees and contractors.

Solutions I implemented:

Complete inventory of mobile devices used throughout the organization

Definition of security and compliance policies via Microsoft Intune for Mobile Device Management (MDM)

Creation of configuration profiles for iOS and Android, including password policies, encryption, and remote lock capabilities

Activation of Microsoft Defender for Endpoint Mobile

Implementation of Conditional Access policies integrated with Azure AD to control access to corporate resources

Leuze Electronics Project – SAN Infrastructure Architecture with Hyper-V

I participated in the construction of a high-availability storage infrastructure based on Storage Area Network (SAN). The objective was to create a robust virtualization environment with Hyper-V, ensuring performance, security, and both physical and logical equipment organization.

Key deliverables:

Planning and organizing racks with SAN switches, storage units, and servers

Configuring iSCSI Targets and Initiators on Hyper-V nodes

Creating volumes, mapping LUNs, and conducting performance testing with failover

Integrating with Active Directory domain and applying security policies for users and groups

Implementing backup and replication with VSS and periodic snapshots

Documenting the architecture with physical and logical diagrams
