Hi there! I'm Markus Yoshizawa,

Computer Science student, focused on areas such as Support and Cybersecurity.
Currently in the process of hands-on-study of tools such as Splunk, Active Directory and Kali Linux tools like Wireshark and Nmap.

Proficient in 3 languages: English (fluent), Portuguese (native) and Japanese (intermediate, with conversational fluency and JLPT N3 certification).
I'm also a big photography enthusiast in my free time :)

Currently on a career transition, where I have been studying and pursuing certifications to validate my knowledge.
I recently concluded Code in Place 2025 (Stanford University), and I'm now currently enrolled in courses like Google Cybersecurity Professional Certificate, among others, all providing certifications upon completion.
To consolidate further the knowledge I have gained, I also plan to obtain the ISC² CC and CompTIA Security+ certifications over the next few months, in addition to the others mentioned before.


Hard Skills (constantly improving) :

  • Active Directory
  • Bash
  • Wireshark
  • Python
  • SQL
