Academic Portfolio
This is a selection of some of the projects I worked on while earning my degree at Southern New Hampshire University. It’s essentially a time capsule of my capabilities and manner of thinking back when I was getting ready to graduate.
Software Design and Engineering
In CS-410: Software Reverse Engineering, I reverse-engineered a legacy program from binary to assembly to C++, and corrected security flaws in the source code of the reversed program. Many of these vulnerabilities were due to the programmer of the legacy code not observing proper considerations of C programming, but the original as well as the reversed and revised programs also lack portability. Both could be enhanced by porting the reversed application to Java, which imposes stricter compile limitations and is also write-once-run-anywhere. This work is the result of that translation from C++ to Java, which has been further modified to produce more modular code.
This artifact originally showcased my ability to reverse-engineer software from binary, but in this revised form, highlights my understanding of object-oriented programming, and how different languages can overlap in programming paradigms. This revision takes the original program and makes it more modular, secure, reliable, and portable.
The program currently uses a HashMap to store the client objects as key-value pairs. I’m well aware that this might not represent a real-world use-case, and a realistic scenario would utilize a database, but it makes a fine structure for expanding and testing the application.
Planned further enhancements include JUnit testing. Source for this project is available at github.com/JimmyBoomBots3000/Banking.
Algorithms and Data Structure
In CS-260: Data Structures and Algorithms, I developed four C++ programs, one each demonstrating a Vector, Linked List, Hash Table, and Binary Search Tree. Each program reads data into its respective structure from a csv file, and allows a user to display all items, search the structure and display a single item, as well as manipulate the structure by adding or removing an item. Over time, these programs have been updated for bug fixes and security, and feature adds such as timing operations to compare performance of different operations.
I admit, this set of programs may seem pedestrian, but I wanted something to show that I understand data structures and can develop algorithms to suit them, and this demo gets straight to the point.
Source code for this project is at github.com/JimmyBoomBots3000/DataStructuresAndAlgorithms.
Databases
In CS-340: Client-Server Development, I was given a specification as well as the following scenario:
Grazioso Salvare identifies dogs that are good candidates for search-and-rescue training. When trained, these dogs are able to find and help to rescue humans or other animals, often in life-threatening conditions. To help identify dogs for training, Grazioso Salvare has reached an agreement with a nonprofit agency that operates five animal shelters in the region around Austin, Texas. This non-profit agency will provide Grazioso Salvare with data from their shelters…
…Grazioso Salvare is seeking a software application that can work with existing data from the animal shelters to identify and categorize available dogs. Global Rain has contracted for a full stack development of this application that will include a database and a client-facing web application dashboard. Grazioso Salvare will use this dashboard to interact with and visualize data from a MongoDB database. The dashboard must be a user-friendly, intuitive interface that will reduce user errors and training time.
What I produced was a web app, written front-to-back in Python. To take this demo out of the classroom (where it ran entirely on localhost resources), I have it hosted on Heroku, and established my own MongoDB cluster to house the same data that was used in the original project. The interface has also been cleaned up a bit, and is now utilizing the Bootstrap front-end framework. Take it for a spin at graziososalvare.herokuapp.com. Heroku 86’d the free-tier hosting, so for now this down.
