My recent work includes building an automated vulnerability-scanning application with Lovable.dev, Nmap, and the OpenAI API. My cybersecurity background includes vulnerability assessment, information security policy improvement, business continuity documentation, threat modeling, and risk modeling for advanced 5G networks. I have also researched Android malware detection using artificial intelligence. I lead a team of four QA testers and value effective testing strategies, cross-functional collaboration, and continuous improvement. I am interested in expanding my expertise in test automation, cybersecurity, and modern software development practices. ## Skills 21 capabilities[Artificial Intelligence](https://jobicy.com/talent/artificial-intelligence.md)[Business Continuity](https://jobicy.com/talent/business-continuity.md)[Cybersecurity](https://jobicy.com/talent/cybersecurity.md)[Data Reporting](https://jobicy.com/talent/data-reporting.md)[Information Security](https://jobicy.com/talent/information-security.md)[Java](https://jobicy.com/talent/java.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Manual Testing](https://jobicy.com/talent/manual-testing.md)[Python](https://jobicy.com/talent/python.md)[Quality Assurance](https://jobicy.com/talent/quality-assurance.md)[Risk Modeling](https://jobicy.com/talent/risk-modeling.md)[Salesforce Administration](https://jobicy.com/talent/salesforce-administration.md)[Salesforce Development](https://jobicy.com/talent/salesforce-development.md)[Software Engineering](https://jobicy.com/talent/software-engineering.md)[SQL](https://jobicy.com/talent/sql.md)[Team Leadership](https://jobicy.com/talent/team-leadership.md)[Test Strategy](https://jobicy.com/talent/test-strategy.md)[Threat Modeling](https://jobicy.com/talent/threat-modeling.md)[Vulnerability Assessment](https://jobicy.com/talent/vulnerability-assessment.md)[Web Development](https://jobicy.com/talent/web-development.md) ## Tech stack & tools Working toolkit ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mysql/mysql-original.svg) MySQL](https://jobicy.com/talent?tool=mysql.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/drupal/drupal-original.svg) Drupal](https://jobicy.com/talent?tool=drupal.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/moodle/moodle-original.svg) Moodle](https://jobicy.com/talent?tool=moodle.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/wordpress/wordpress-original.svg) WordPress](https://jobicy.com/talent?tool=wordpress.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/java/java-original.svg) Java](https://jobicy.com/talent?tool=java.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/javascript/javascript-original.svg) JavaScript](https://jobicy.com/talent?tool=javascript.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/python/python-original.svg) Python](https://jobicy.com/talent?tool=python.md) ## Experience Career history ### Senior Associate, Solution Engineer · Pfizer Jan 2021 – PresentI develop software solutions that support sales representatives in drug allocation using Salesforce CRM.
