Danielle McNeill's Computer Science ePortfolio
Welcome! This portfolio represents my growth and learning throughout the Computer Science program at SNHU. It includes a collection of artifacts enhanced across key areas: Software Design & Engineering, Algorithms & Data Structures, and Databases. My work demonstrates not only technical skills but also a dedication to creating efficient, maintainable, and user-centered solutions.
Professional Self-Assessment
My self-assessment provides a reflection on the skills I’ve developed in programming, teamwork, database design, and secure development practices. It serves as an introduction to who I am as a developer.

Enhancement One: Software Design & Engineering
This Java-based application was originally created in IT 145. For this enhancement, I refactored the code to improve modularity, added consistent input validation and error handling, and implemented design principles to make the code more maintainable.
Enhancement Two: Algorithms & Data Structures
Building on the same Java application, I added a compatibility matching algorithm using weighted scoring, lists, and filters to help match adopters with suitable service animals. This enhancement highlights my skills in algorithm design and data manipulation.
Enhancement Three: Database Integration
For this final enhancement, I integrated a SQLite database into the application. This replaced in-memory lists, provided data persistence, and made the app scalable. I also added basic SQL injection protection with prepared statements.

Full Stack Cloud Project
In my full stack course, I migrated a web application to AWS using serverless technologies like Lambda, API Gateway, and DynamoDB. I also used Docker and Docker Compose for containerization. This project demonstrates my skills in cloud architecture, security, and scalability.
