What I'm looking for

I'm seeking an entry-level SOC Analyst, Junior Cybersecurity Analyst, or Security Operations opportunity.

Through hands-on cybersecurity projects, I developed a Python packet-sniffing script, captured network traffic to a PCAP file, and analysed TCP, UDP, and ARP activity in Wireshark.

I also used Python to investigate authentication logs for repeated failed logins and suspicious source IPs, and used Burp Suite to assess SQL Injection and access-control weaknesses in simulated web applications. In a secure login project, I used parameterized SQL queries with Python and SQLite to reduce SQL Injection risks.
