Work and Research

Designed a web application to investigate the interaction of automated adversaries operating in simulated enterprise network environments by utilizing open source tools such as Microsoft CyberBattleSim and D3-force. Source code available here.

Leveraged ML.NET to implement Time Series Forecasting; ran benchmarks with synthetic and real-world data and conducted competitor analysis

Collaborated with 8 fintech companies to coordinate internal project proposals relating to the processing of corporate documents using preprocessing techniques and OCR
Lead a team of 6 undergraduates and coordinated weekly milestones
Held weekly meetings to discuss progress and timelines with team members and company sponsors

Designed the foundation for a web platform that would encapsulate a bare-bones C++ implementation of several cryptographic and multi-party computations
Worked on transcribing the C++ codebase into JavaScript using Emscripten, a tool that compiles C++ into WebAssembly
Setup a MySQL database for the storage of credentials and an SMTP server to handle email tokens
Followed many security best practices, including salting/hashing passwords, CSRF tokens, CSP headers, and creating TLS certificates using Let'sEncrypt

Worked on circumventing corporate firewalls using NAT traversing servers for WebRTC applications
Used Docker, Kubernetes, Terraform, and Google’s Cloud Platform to automate the setup of said servers and scale the infrastructure

Worked with a team of biotech investigators and facilitated CAD design, 3D printing, and Arduino circuit logistics to design a syringe pump embedded robotic arm to be used for precise bio-filament placement
