About Me

Hello, I am Rosemary Davies!

I am a Linux systems administrator with a strong DevOps focus, experienced in managing infrastructure across diverse environments at scale. I’ve learned to herd computers in different contexts. I have managed Windows lab environments and thousands of engineering servers! I enjoy the problem solving that comes with inheriting different ecosystems. I love automation (ansible) and scripting (bash/python) to drive reliability, performance, and efficiency.

I value curiosity, teamwork, and continuous learning. As someone who entered the field later than most, I prioritize accessibility and knowledge sharing.

Cybersecurity

Cybersecurity is a core extension of my work in systems administation. I focus on understanding real-world challenges. Security doesn't happen in a vacuum. Imperfect systems are the norm. Users make mistakes, budgets are limited, IT inherits technical debt, and miscommunication happens across groups. By understanding attacker methodologies, I better understand how to recognize and defend.

I currently serve as captain of Hack Manhattan’s CTF team, STON3F1SH, and was previously a member of the GNU-E-Ducks. Through CTF competitions, I’ve developed hands-on experience in areas such as digital forensics, web application security, and OSINT. I’m also enthusiastic e about mentoring and actively help onboard new participants through Hack Manhattan’s Red Team study group.

CTFs completed in 2026 include:

• SANS Holiday Hack
• DC862
• ScarletCTF
• PascalCTF
• LA CTF
• DiceCTF Quals
• picoCTF

Outside of work

I enjoy the creative side of computing (hence computer poetry). I'm a member of a shared Linux server Tilde Town.

When I'm not sitting in front of a computer, you can find me picking up trash around different NYC neighborhoods with the Pickup Pigeons on Thursdays and as a volunteer bike mechanic at the Times Up! bike co-op. My hobbies include making papercraft, using my soroban (abacus), and taking long walks in the city.
