Obi Nelson
@obinelson
Cybersecurity and data science student who designed a secure Cisco Packet Tracer network and automated retail data analysis.
NigeriaWhat I'm looking for
I designed a secure small-office network in Cisco Packet Tracer for a 20-employee startup, configuring IPv4/IPv6 addressing, VLANs, and subnetting. I also implemented SSH, DHCP, and DNS, web, and FTP servers for internal operations.
On my Customer Behavior Analysis project, I automated a retail dataset analysis pipeline in Python, reducing manual reporting time by 40%. I created Matplotlib visualizations and presented the findings in a report.
I conducted statistical analysis on a 1,000-row dataset using Python to identify customer behavior trends. I’ve also created a Python script to automate IT support ticket logging for 100+ monthly requests.
I’m studying for a Bachelor of Science in Statistics at University of Lagos (UNILAG), with coursework in cybersecurity fundamentals, Python programming, data analysis, statistical modelling, and database management. I’m seeking a data science or cybersecurity internship where I can apply my Cisco Packet Tracer project experience.
