About

In my career as a cybersecurity professional, I have specialized in penetration testing across diverse domains, including web applications, APIs (both blackbox and whitebox testing methodologies), mobile applications, and network infrastructure. I possess extensive experience in evaluating operating systems and services security configurations, as well as conducting cloud security reviews. My primary responsibilities have involved performing thorough security audits, conducting forensic analyses, and preparing comprehensive reports to outline vulnerabilities and recommendations for mitigation. Additionally, I excel in securing network, cloud, and container infrastructures, collaborating closely with developers to address security concerns and ensure the effective implementation of fixes. Furthermore, I contribute to enhancing internal security measures through the development of specialized tools tailored to organizational needs. During my tenure, I have also been actively involved in assessing cybersecurity risks across various platforms and recommending appropriate solutions to bolster defenses. My background includes valuable experience gained during a student internship at an IT department, where I engaged in a range of IT support tasks for clients, undertook Linux administration duties, and automated routine operational processes. These experiences have not only expanded my technical proficiency but also equipped me with a holistic understanding of cybersecurity practices within dynamic organizational environments.

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
