Security Architect at https://www.genomicsengland.co.uk/.

I am an expert with 16 years of experience in Linux, networking, cybersecurity, and infrastructure.

I hold AWS Specialty certifications in Advanced Networking and Security, designing and reviewing complex infrastructure solutions while ensuring alignment with CIS, NIST, and AWS Well-Architected Frameworks.

I regularly collaborate with C-level executives and engineering teams, providing architectural oversight and strategic input.

I am a key member of various cybersecurity committees, influencing decisions on risk factors and security strategies.

My comprehensive hands-on expertise spans:

With these technologies, I have created and led architectural designs and architectural reviews. I designed, planned and implemented automation with these services I lead incident responses. I designed, planned and implemented Zero Trust initiatives, and integration of services for authentication with devices posture validation - Cloudflare ZTNA, CrowdStrike, and Okta.

I also run personal projects like HackerClub.Net, tech timeline https://www.antoniofeijao.com/timeline-technology-and-cybersecurity/ and CyberAntonio.com, which are some of my cyber security notes and a JavaScript playground.

Pre-cloud, I earned certifications of Red Hat Certified System Administrator - RHCSA, Cisco CCNA and Cisco CCNP Security - Cisco Firewall Security Specialist.

I possess deep expertise in automation using Bash shell scripting and Python.

I bring a wealth of knowledge in designing, troubleshooting and implementing CrowdStrike Falcon, Cloud Security, and Falcon Forensics.

With Cloudflare, I possess deep expertise in custom and managed Web Application Firewall (AWF) rules, rate limiting, payload decryption investigation and reverse engineering, Zero Trust designs, and authentication policies.

My leadership extends to offensive security, penetration testing, mentoring teams, securing serverless and web applications, and delivering deep-dive technical demos.

Outside of work, I am passionate about space physics and scientific exploration. I am an avid runner, swimmer, snowboarder, and Tough Mudder enthusiast.

Though not active on social media, I enjoy technology and history podcasts, as well as a good science-fiction film or documentary.
