Work Experience

The system includes such parts as lead processing, repair estimator, marketing attributions, analysis of seller situation, agreements, disposition, and fulfillment.
Created an auto-dialer that allows the user to call multiple numbers at the same time and connect the call to the agent only when the call is answered. It allows for call optimization and automatically handles "answered by machine" calls.

DeimosC2 is a post-exploitation command and control (C2) tool that leverages multiple communication methods in order to control machines that have been compromised. It is entirely written in Golang with a front end written in Vue.js.
I did all front-end work on this project. The most interesting parts of this project are communication with the server through WebSocket, a terminal component that imitates bash shell, a fully functional file browser component, multilingual UI with themes, and reusable components that keep code nice and clean.
