What it does:

Domain Scout is the primary GUI to view vulnerable domains found by Domain Scout API. Domain Scout API identifies disposable email addresses used as contact methods in WHOIS records. Domains are collected using Certstream Server Go which streams Certificate Transparency logs continuously to a websocket connection. Domains are extracted from the data stream and WHOIS queries are subsequently made to identify contact email addresses which are compared against a list of 15k+ known disposable email domains. If a disposable email address is found, the domain and associated data is added to the database and displayed in Domain Scout.

Key Features:

• TLS certificate transparency log parsing and analysis
• Disposable email detection algorithms
• SQL database for storing results
• Batch processing capabilities

What it does:

This program implements a simple shell that can run commands in the foreground and background, with input and output redirection. It also handles built-in commands such as exit, cd, and status. Signals such as SIGINT, SIGCHLD, and SIGTSTP are handled as well. Comments can be added to the input by starting the line with '#'. Blank lines are ignored. The '&' character can be used to run a command in the background. Program will terminate upon 'exit' command.

Key Features:

• Command execution in foreground/background
• Input/output redirection (>, <, >>)
• Process management and job control
• Built-in commands (cd, exit, jobs)

What it does:

Program displays title and programmers name, followed by an introduction explaining the program. Program then prompts user to enter 10 signed decimal integers in range of 32 bits/number. Input is read in as a string and converted from ASCII to decimal. Each input is then checked for if it is valid. If it is not valid, the program will display an error message and prompt the user to re-enter the number. If the number is valid, it is stored in an array. The program then displays the numbers entered, followed by the sum and average for the values inputed. Results are converted to ASCII and then displayed to the user along with a list of the numbers entered. The program then displays a goodbye message and exits.

Key Features:

• User input validation and error handling
• ASCII to decimal conversion
• Array storage and management
• Mathematical calculations (sum, average)
• Decimal to ASCII conversion for output
• Input range validation (32-bit signed integers)

What it does:

A comprehensive web application for managing engineering projects, including design documents, requirements tracking, user management, and project workflows.

Key Features:

• User authentication and role management
• Document version control
• Project tracking and milestones
• Requirements management system
• RESTful API endpoints

What it does:

An church website serving the LDS stake in Central Point, Oregon, providing event information, resources, and updates.

Key Features:

• Events & management
• Church announcements
• Resource sharing
• Responsive design for all devices

What it does:

A time-based one-time password (TOTP) implementation following RFC 6328 standards, providing secure two-factor authentication.

Key Features:

• RFC 6328 compliant TOTP
• 30-second token rotation
• Secure random key generation
• QR code generation
• Elixir/Phoenix integration

What it does:

Using the python module Turtle, I created the classic game of snake. The program initializes a 600px x 600px window in which the current score and high score are displayed, along with the "snake" and "food" objects. The up, down, left, and right arrow keys are used to control the movement of the snake head. Upon collision with food objects (in this case turtles), a new segment is added to the snake corresponding to the color of the food object.

Key Features:

• Arrow key controls (up, down, left, right)
• Score and high score tracking
• Snake growth mechanics
• Color-coded food objects
• Python Turtle graphics

What it does:

A cloud-based course management system built on Google Cloud Platform, providing educators with tools to organize and deliver course content.

Key Features:

• Course content management
• Student enrollment tracking
• Assignment submission system
• Google Cloud integration
• Scalable architecture
