What I'm looking for

I'm looking for an entry-level SOC, digital forensics, incident response, or threat-hunting role where I can investigate alerts, analyze telemetry, apply DFIR skills, and grow through hands-on security operations work.

I investigate simulated enterprise threats through SOC alert triage, network forensics, and memory analysis. My work focuses on turning endpoint and network telemetry into actionable indicators of compromise.

Through CyberDefenders DFIR scenarios, I've analyzed PCAP files in Wireshark to isolate UDP exfiltration and command-and-control traffic. I've also used Volatility to examine compromised memory dumps, identify suspicious process relationships, injected code, and process hollowing.

In TryHackMe SOC environments, I've used Splunk and Elastic Stack to analyze Windows Event Logs, firewall traffic, and web server logs. I correlate alerts, distinguish benign activity from true positives, investigate phishing payloads, and map adversary behavior to MITRE ATT&CK and the NIST incident response lifecycle.

I've published technical DFIR investigations on Medium covering memory forensics, PacketMaze network traffic analysis, and Linux threat hunting. I bring clear incident reporting alongside practical analysis of malware artifacts, exfiltration vectors, and remediation needs.
