About

"I’m proud of the way I think when things go wrong" I believe this mindset matters to me. I genuinely enjoy working as a security professional because of the adaptability which keeps me motivated. I’ve been working as a SOC Analyst for over a year and half where I’ve reported multiple true positives and even managed the full security posture of an organisation. I’ve had to learn fast and adapt quicker to prove myself in environments where there’s no room for guesswork. One moment that really reflects who I am is when I once investigated a fake job offer that was circulating like a scam completely outside of work. Treated it like a real world CTF tracked the domain infrastructure and broke it down just to protect others from falling for it (You can find the full story on my LinkedIn feed). That’s the kind of curiosity and drive I bring on and off the clock. I’m quick to learn and not afraid to get my hands dirty. More than anything I care about growing with a team and organisation and learning every day. If you’re after someone who’s not only technically solid but also emotionally aware and professional I’d love to be that person on your team.
