• Completed various practices during course works at OSU with five dean’s list qualifications and an overall/major GPA of 3.72/3.84

• Participating in the Cincinnati Zoo’s project designing and building automatic RFID involved feeding scheduling and information recording system. In particular, designed, developed and deployed the physical system hosting on many Raspberry Pi 4s interpreting instructions and data from multiple RFID antenna and backend server, executing tasks to multiple feeders, recording to internal database while automatically maintaining system autonomy and integrity even if server is disconnected or file is corrupted. Also responsible for creating a docker container for easy deployment hosting a Django server and database created by teammates.

• Participating in a project at OSU creating a containerized IOT honeypot and gathering hacker data via hidden loggers. Responsible for creating loggers gathering data from the docker container and KVM and storing them to a hidden secure database. Also responsible for renting and setting up the Kernel Virtual Machine we are using as well as the docker environment for the simulated IOT device.

• Practice hardening and defending operating systems at OSU VMWare environment from other students during information security project course.

• SIMPLE DIFFUSION – AS PERSONAL PROJECT

Since the earlier release of Stable Diffusion this year, several web ui have poped out on the internet, But almost all of them focused for single client local operation for stable diffusion. This project is aimed to create a RESTful, simple, easy to use web ui that is suitable for deployment on  servers serving many clients. Still under development now. 

Skills involved: Stable Diffusion; Flask; HTML5; CSS; jQuery

• RADIUS Traffic Simulator – At SS8 Networks Inc.

It consists a server and multiple clients running freeRADIUS. They will use scripts I wrote to simulate legit RADIUS traffic complete with client ID and mock traffic data. Traffic is then captured using wireshark and replayed on our test network to test our product before handing over to customer. Project have information specific to customer and stored in company database thus no links here.

Skills involved: Python; WireShark; FreeRADIUS

• NOKIA VSIM CLI INTERFACE – AT SS8 NETWORKS INC.

This is a CLI interface completely written in python in order to simulate the NOKIA VSIM interface for their high performance routers. Our company product will interact (SSH into) with such interface and configure parameters and targets in it. I was tasked to create such a simulated interface so we can test functionality of our product. Interface completely written in python and will give desired output when given input. Able to function standalone and running in Docker container and able to function as a interface over SSH. 

Also able to store configured data in csv for verification. Program uses stacked folder structure and multiple standalone scripts to simulate bizarre behavior of said interface. Project have customer information and stored on company server thus no links here
