The first steps
My first steps in cybersecurity.
Senior AI Security Engineer at CookUnity · Moving towards AI Safety
I am a Senior AI Security Engineer at CookUnity, where I am building the AI Security practice. My background is in offensive security, application security and assessing AI systems.
I am working towards a transition into AI Safety. The AI Security Bootcamp in London helped clarify that direction: I want to apply my security experience to making AI safer and more beneficial, while strengthening my machine learning and research foundations.
Through PhiloCyber, I share that journey in articles, videos, talks and conversations in the media. I still have a lot to learn, and I want the work I do along the way to be useful to others.

In the media
From London to conversations in Bariloche: sharing what I learned at AISB about AI risks and how to contribute to safer development.
Practical resources I am developing and sharing, with their current stage and a direct way to explore the work.
Drafts under review
I am organizing practical approaches to assessing AI systems, from scoping an engagement to documenting findings.

Learning with others and sharing knowledge are also part of my work in security.
Co-founder
A cybersecurity community rooted in Argentina and Latin America, developed with the founding team around shared knowledge, events and collaboration.

I co-founded the Hack The Box meetup in New Zealand and later joined the Argentina chapter as an organizer.
Visit communityPhiloCyber began as my technical blog. Over time I added more practical resources and a YouTube channel so the work could be useful in different formats.
I later tried to turn it into a consultancy. Today it has a different role: my personal home for writing, resources and a developing contribution to AI safety.
Training and certifications that have accompanied my work across offensive security, application security, cloud and AI.

“I had the pleasure of working with Richie when he first moved to New Zealand. He stood out to me during the interview process, partly because he was friendly and personable but mostly because he clearly demonstrated a passion for cyber security, particularly with web applications, and an eagerness to develop and hone his skills. These were the core characteristics he brought to his role. He was always looking to learn and do his best on every engagement and would actively try to do better on the next one. His penchant for development wasn't limited to himself as he would also actively share his knowledge and help other members of the team. It's been exciting to see Richie be so involved with both local and online security communities and I would happily jump at the chance to work with him again.”Recommendation 1 of 6
