Welcome to my portfolio

Full-Stack Engineer, Cybersecurity Associate

Introduction

My name is Oluwaseyi Darren Adetunji, i'm a self taught developer, web designer and most passionately of all cyber security, my repertoire of skills range from coding in a variety of languages, scripting in both python and bash, designing in figma, analysing network traffic using wireshark, improving my skills via help from Cisco's netacad and using burpsuite to analyse the the security of my various web applications to learning new languages such as german, french and italian which is inspired by my love for the old assassin's creed games. I am also proficient in hardware aspects of networking and computing. Lastly the list of my soft interests range from poetry to studying history and occasionally appreciating oth renaissance and classical paintings. Thank you for reading so far and if i would leave you with anything it is this quote: The quieter you become the more you hear - KALI LINUX | Rumi | Ram Dass.
