About Me

I am a Senior at the University of Maryland, College Park studying Computer Science and minoring in Mathematics. I had a previous software engineering internship at AnaVation LLC where I collaborated with other interns in an Agile workflow. I learned how to host web pages using AWS cloud services and javascript and node.js and how to identify and target computers viewing our web pages. I have taken courses such as Object Oriented Programming, Computer Systems, Computer Network Security, Computer Networks, Algorithms, and many more that have made me a well rounded student in several Computer Science disciplines.

Projects

Classification with Neural Networks

  • Deployed a multi-layer perceptron network to classify an image of a handwritten digit (0-9)
  • Trained the network for 100 epochs of 50,000 training images using backpropagation and stochastic gradient descent
  • Tested 2,000 images against the network’s trained weights and biases achieving an accuracy of 97%

Bank and ATM Security

  • Developed an ATM that sends a users’ balance, withdraw, and deposit requests to a Bank via a router
  • Used RSA encryption on packets sent through the router to prevent man in the middle attacks and ensure the confidentiality and integrity of user data such as passwords, pin numbers, and account balances
  • Utilized input validation to prevent SQL injections, buffer overflows, segmentation faults, and malicious brute force login attempts in order to uphold availability of data

Payload Delivery Platform

  • Collaborated with 3 Software Engineer Interns, 1 Project Manager, and 1 Product Owner to develop a payload delivery platform
  • Implemented 5+ APIs such as Google Authenticator for a 2FA login page, Ably for pub/sub communication amongst microservices, and Twilio for email and SMS messaging
  • Formulated an algorithm for device identification using IP address, user agent string, geo location, keyboard languages, and other fingerprinting APIs
  • Wrote AWS Cloud Formation scripts to provision 5+ AWS resources needed for the creation, modification, and deletion of endpoints
