I’m a Software Engineer engineer with strong skills in development, operations and networking. I hold Exceptional Talent in Digital Technologies awarded by Tech Nation UK in 2020. I can write and maintain code in three programming languages: Go, C++, and Perl. I have a passion for Linux, which I’m able to use at scale on thousands of machines. I have mastered expertise in both distributed service development and network security. I use my skills and experience to address DDoS attacks, which I consider to be one of the most critical global modern day threats.
