System Administrator • IT Specialist • Automation & Support

Vasyl Semenchenko

I work at the intersection of IT support, networking, security, and automation. I optimize routine processes, improve service stability, and adapt quickly to new technical domains.

I have 2+ years of hands-on experience in IT support, network monitoring, and process automation. I designed and implemented a Telegram bot for a support team that saves about 60 person-days every month. I have also worked with Splunk, JIRA, MS SQL, SQLite, Python, and OWASP Top 10 approaches. I am exempt from military service registration.
