Case Study 2 of 6: FullStack Development of ScriptChain Health Along With AWS RDS Encryption with EC2 and Private Subnets

I developed the backend API and services on site such as email system sender, converting static to dynamic database in SQL, duplicate entry checkers, storing information from forms into encrypted data tables within already encrypted database. I connected the website and database to private subnet in AWS RDS through running an EC2 statement as a Bastion host (jumping server for subnet) providing extra security. I also developed dynamic responsive html email templates and the service to be able to send html through Nodejs through the handlebars library. I developed multiple services identifying ids of encrypted columns/rows of data tables, and token encryption. I identified/debugged and resolved many underlying issues and overall pitched in my own ideas that I believed would make code more efficient or organized and proposed new ideas to benefit the entire website itself. Front-end wise, I developed various pages on the site through html/CSS/typescript including the capability statement page, request access page, about us page, contact us page, home page, terms-conditions page, privacy policy, subfooter located at the bottom of every page. I utilized Bootstrap, jQuery, Django, and Angular frameworks to accomplish this and adjusted for responsiveness between different screen sizes and devices.

Case Study 3 of 6: GlobalChat - (Mock Telegram Features)

I created this application from inspiration of the safest messaging service on the planet, Telegram. There is no need for real name, email, or phone number required to access the global chatroom. A username is reset every time a client joins to assist with personal security. This application contains a fully automated swear word filtration system. Our mission is to target every age group and provide some sort of long term benefit to everyone. There is also a multi-second delay when sending messages to allow for a cancellation of the message being sent if a new client pop up notification appears or any other reason. When a client connects or disconnects, the server notifies everyone.

Case Study 4 of 6: EatSafeBeSafe- Restaurant Health Inspection Tracking

EatSafeBeSafe is an application striving to improve the good health and wellbeing and spread knowledge of the matter to others (One of The United Nations Sustainable Development Goals). Essentially, my site addresses all restaurants in a concentrated area that have failed their health inspection. It then provides the violation type, latest date of inspection, and location on pinpointed location map through an opensource US map api. Over 600 million people are affected by not knowing what they eat. This will hopefully advance in a direction to inform people to become healthier. It would also motivate restaurant owners to keep not only their outside, but their kitchens in flawless condition as well.

Case Study 5 of 6: Hotel Reservation Management

The application provides four user scenarios: Creating a customer account, Searching for rooms, Booking a room, Viewing reservations. The application provides four administrative scenarios: Displaying all customers accounts, Viewing all of the rooms in the hotel, Viewing all of the hotel reservations, Adding a room to the hotel application. The application allows customers to reserve a room. The application has customer accounts. Each account has: A unique email for the customer: RegEx is used to check that the email is in the correct format (i.e., name@domain.com). A first name and last name. The email RegEx is simple for the purpose of this exercise and may not cover all real-world valid emails. For example "name@domain.co.uk" would not be accepted by the above RegEx because it does end with ".com".

Case Study 6 of 6: Facial Recognition - Emotion/Distress Detector

The emotion-facial detection program uses cameras, along with public databases such as deepface emotion analyzing technology to make a prediction as to what emotion a person is feeling based upon their facial expressions. It was created to help American Airlines with improving its customer experieince. It would detect stress and distress within passengers before escalation. I trained a Deepface neural network and utilized OpenCV's facial recognition functions and methods to replicate facial recognition software capable of identifying emotions. As of now, every three seconds we update a table to display the information from the prediction made. Main libraries used were tkinter for dynamic tables, OpenCV for camera-project connection, deepface for training, and matplotlib to analyze the data.
