What I'm looking for

I seek a full-time remote security role where I can integrate security into development lifecycles, automate defenses, respond to incidents, and grow technical leadership within a collaborative, fast-paced team.

I am a proactive, detail-oriented security engineer with 3+ years' experience in information security, technical support, and software development, focused on securing systems and reducing vulnerabilities through hands-on scripting and automation.

I have delivered measurable results: reducing vulnerabilities by 15% at Booking.com, achieving a 98% first-contact resolution rate, and cutting analysis time by 20% through Python and Bash automation. I also developed a Python vulnerability-scanning tool in my capstone and helped clients reduce downtime by 25% through rapid incident response.

I thrive in fast-paced, remote environments, collaborating with engineering and DevOps teams to integrate security into development lifecycles, implement patch management, and document clear, actionable security controls for stakeholders.
