What I'm looking for

I seek a cybersecurity role focused on incident response, threat detection, and remediation within collaborative teams that prioritize data-driven security improvements and professional growth.

I investigate large-scale security incidents and analyze attack vectors to recommend practical defenses. I researched a breach that exposed 280,000+ customer records and analyzed the Target retail breach affecting 110 million customers, identifying POS and network segmentation vulnerabilities.

I assess malware threats, social engineering tactics, and network weaknesses, and I propose enhanced security protocols, threat detection, and incident response measures. I also apply data analysis skills—using Microsoft Excel functions, pivot tables, and charts—to drive service and security improvements.

I am pursuing a National Diploma in Computer Science at the Federal College of Animal Health and Production Technology and I bring a research-driven, detail-oriented approach to security challenges; I communicate findings clearly and act on data to reduce risk. I work in English and Yoruba.
