About
I am a Cybersecurity Engineer with hands-on experience in SIEM/XDR operations, incident response, and detection engineering.
I'm responsible for core security operations, working across infrastructure, development, and business teams to investigate incidents, analyze security data, and support infrastructure-level security decisions - regularly collaborating with senior engineers, technical leads, and C-level stakeholders.
My experience spans threat detection, vulnerability management, identity security, and application security reviews, including vendor risk assessments. I also bring a background in software development, applying engineering skills to build internal tools and automate security workflows using scripting and AI-based solutions.
