CyberSecurity Associate at Sattrix Information Security | Top 1% CyberSecurity Learner on TryHackMe | ArcSight | Splunk | NewEvol

I have a strong and evolving interest in cybersecurity and ethical hacking, proven by my top 1% rank on TryHackMe, completion of SOC Fundamentals, multiple Udemy courses, and active participation in CTF programs and practical hacking series. Currently, I work as a Cybersecurity Associate at Sattrix Information Security, where I serve as an ArcSight Administrator and have hands-on experience with SIEM tools like Splunk and NewEvol. Alongside cybersecurity, I also have a background in web development with experience in HTML, CSS, JavaScript, and Python scripting. I’m deeply committed to continuous learning and real-world application, with a consistent track record of completing certifications and challenges. Despite ongoing health challenges that impact productivity, I remain focused on deepening my expertise and building a successful career in cybersecurity and ethical hacking.
