@joopimentel
Information security analyst specializing in automation, threat intelligence, and phishing detection.
I am an information security analyst with hands-on experience in incident response, threat intelligence, and automation. I have built detection capabilities using Splunk, MISP, YARA, and Python to improve visibility and reduce false positives.
I developed and maintained a custom phishing detection platform (Angular, Python Flask, SQL) on AWS that aggregates malicious domains, leverages AI for URL classification, and automates takedowns, significantly reducing analyst workload and response time.
My background also includes software engineering with React/React Native, projects in malware analysis, reverse engineering, and contributions to automated data pipelines and reporting that inform stakeholders using the MITRE ATT&CK framework.
