About

Professional summary

I am an early-career IT professional with hands-on experience in technical support, hardware and software maintenance, and network configuration.

I have provided N1/N2 user support, diagnosed technical issues, installed and reinstalled operating systems, configured devices, and assisted users with backup and data recovery.

I work with Windows and Linux environments and have practical knowledge of networking, routers, shell scripting, Python, and C. I am also familiar with troubleshooting tools and service desk workflows.

Alongside IT support, I have experience in industrial maintenance, electrical and electronic diagnostics, automation, and preventive and corrective maintenance. This background has strengthened my analytical thinking and troubleshooting capabilities.

I am currently studying Computer Networks and have completed technical training in Electronics. I am interested in growing in technical support, automation, cybersecurity, and information security.

I have also developed personal projects involving Kali Linux tooling automation, local AI for WhatsApp automation, API integration, workflow automation, and data management.
