Freelancer Overview

I am a technical specialist with a solid background in turning raw system data into clear, structured intelligence. My experience is rooted in technical data annotation, particularly when it comes to categorizing log sources, event visibility, and security telemetry within SIEM platforms like Splunk. This work has built my ability to accurately identify and tag complex datasets, such as network traffic patterns, port scan outputs, and OSINT digital footprints, which are essential for training both security models and students to recognize threats. I am highly skilled at taking raw data from tools like Nmap and Kali Linux and turning it into organized, labeled reports, while maintaining deep expertise in tagging phishing indicators and AI threats like voice cloning. What really sets me apart is how I combine hands-on technical work with instructional leadership and professional certifications. With credentials like the Google Cybersecurity Certificate and AWS Certified Cloud Practitioner, I bring a strong understanding of data integrity and cloud environments to every labeling project. My time as a Cybersecurity Instructor and my role mentoring the 100 Day Cybersecurity Challenge have proven that I can handle large scale data projects, keep my accuracy high under tight deadlines, and turn complicated findings into professional reports. I am very comfortable managing data within terminal environments, SIEM dashboards, and cloud infrastructures to ensure all workflows meet rigorous professional standards.

Digital Footprint and OSINT Risk Assessment

TextEntity Ner Classification
I handled an OSINT research project where I investigated the digital footprint and online reputation of a local business to find security risks. My specific task involved Entity NER Classification where I gathered unstructured data from various open sources and manually tagged key information like social media metadata, public records, and online mentions. The project involved a deep dive into the business's web presence to ensure a complete and realistic view of their digital exposure. I kept the quality high by verifying the data across multiple sources and documenting my recommendations in a final report to help reduce digital risks and improve their online management.

Network Vulnerability & Traffic Data Annotation.

TextEntity Ner Classification
I handled a project that focused on network reconnaissance and vulnerability assessment using Nmap on Kali Linux to find potential attack surfaces. My specific task was Entity NER Classification where I manually picked out and tagged technical data points like IP addresses, open ports, and service versions from raw command line outputs. The project covered a multi-host network to make sure I had broad data visibility and realistic results. I made sure to follow strict quality measures by cross-verifying the scan outputs and documenting every finding in a professional analysis report to keep everything technically accurate and clear.
