My current role at NTT Security is Chief Architect where I'm developing cloud native Cyber Security solutions in Amazon Web Services (AWS), Micrsoft Azure and host based appliances using container technologies such as docker.I'm a very passionate and creative leader and technician with focus on IT Security and systems administration. I have experience to work with international teams in Europe, Asia and USA. DevOps / GitOps methodology and automation has been proven to be a very important cornerstone in our success. I have managed seven engineers as Technical Operations manager in a very versatile environment with many moving targets and quick changes. I believe that communication and delegation are very important as well as inspire the team with a great commitment and pride to the work we do. I have deep knowledge in Unix-like computer operating systems and computer networks. Ubuntu, OpenBSD and VMware are a few platforms I have been focused on but Redhat/CentOS, SUSE and Windows server are systems I'm working with on daily basis. I have experience of building and maintain Tier 4 data center, planning and deployment of international services/CPE equipment and network infrastructure.Nagios-based monitoring platforms like op5 and Naemon is also something that really caught my interest and the development of Naemon became a hobby of mine.
