01 / path
From code to infrastructure.
My story in technology began at Colégio Cotemig, where I started studying programming. In my third year, I took a mobile development course and began my first job as an apprentice at Construtora Sant’Anna while still in high school. After graduating, I joined WeComply as a software development intern, an important experience that strengthened my full-stack foundation. Over time, I realized that although I enjoy coding and have built solid skills, I feel more at home in infrastructure. I now work in IT infrastructure and operations at Dental Sorria, part of Grupo Bunzl, using my software background to automate tasks and improve processes. My next goal is to grow into a Cloud & Infrastructure Engineer.
Software development
After graduating, I joined WeComply as an intern and built my full-stack development experience.
Infrastructure & operations
At Dental Sorria, part of Grupo Bunzl, I found the area that fits me best. I now combine infrastructure, automation, and my software background as I work toward Cloud & Infrastructure Engineering.
02 / who I am
Who am I outside technology?
Away from screens, I like enjoying life, discovering new places, and spending time with the people I love. I’m passionate about music, especially corridos tumbados, afro house, and MPB. I’m also a devoted Atlético Mineiro supporter, following Galo through the good times and the hard ones. I love traveling, discovering new cultures, and having different experiences. In the end, I’m curious, easygoing, good-humored, and enjoy making the most of every moment.

Information security in practice.
How can we identify behavior that falls outside an organization's security policies?
This section presents three scenarios inspired by real situations from my professional experience, showing how I use security tools, log analysis, and evidence correlation to identify risks, investigate events, and help improve the corporate environment.
Case study 01
Identifying recurring access outside working hours
- Cisco Umbrella
- DNS Security
- Log Analysis
- The scenario
During security reviews, I identified recurring patterns of activity on corporate devices during weekends and outside working hours.
- My analysis
I used Cisco Umbrella records to examine the timing, frequency, and destinations of DNS queries, looking for repetitive behavior and possible inconsistencies with corporate policies.
- Outcome
Following alignment with management, the analysis contributed to implementing access restrictions outside working hours, including weekends and previously defined time windows.
Case study 02
Correlating evidence of use outside working hours
- Microsoft Intune
- Cisco Umbrella
- Corporate Logs
- The scenario
How can we check whether activity recorded on a corporate device is consistent with authorized usage times and conditions?
- My analysis
I correlated different sources of information:
- Device activity records in Microsoft Intune.
- DNS queries and timestamps recorded by Cisco Umbrella.
- Working-hour records provided by the responsible departments.
- The history and frequency of observed events.
The aim was to build a timeline of events, identify inconsistencies, and distinguish technical evidence from possible interpretations.
- Outcome
The analysis made it possible to document the patterns found and forward technical information to the responsible management team for evaluation and appropriate action.
Case study 03
Investigating unauthorized applications on corporate devices
- Cisco Umbrella
- Windows
- Endpoint Analysis
- Corporate Security
- The scenario
Identifying signs of games, emulators, and applications that were incompatible with corporate device usage policies.
- My analysis
The investigation combined different sources of evidence:
- DNS records associated with services and applications.
- Checks of software and artifacts present on the device.
- Analysis of device settings and permissions.
- Information provided by the responsible teams and additional technical records.
Correlating this evidence made it possible to evaluate the occurrence without relying exclusively on DNS records.
- Outcome
The investigation helped identify risks related to unauthorized applications and excessive privileges, supporting recommendations to restrict software and review device permissions.
Anonymized case studies, with no disclosure of employees, internal records, or confidential information.
