My Recent Projects

During my time at the University of South Florida (USF), I completed a variety of technical and academic projects. These projects showcase my skills in software development, cloud computing, big data processing, and GPU programming.

1. AES-256 Decryption Program

Spring 2024

Description:
Developed a Python program that securely decrypts encrypted text using AES-256 encryption in CBC mode. Focused on proper key management, IV validation, error handling, and restoring original plaintext formatting. Implemented integrity verification to ensure secure data decryption and prevent corruption

Skills Used:
Python, Cryptography, Cybersecurity, Data Recovery

A computer monitor displays a Visual Studio Code interface with a dark theme. The screen shows lines of code written in JavaScript or HTML with syntax highlighting. The code includes functions, variables, and elements typical of web development. The background reveals a dimly lit office environment.

2. Spatial Distance Histogram (CUDA Project)

Spring 2024

Description:
Designed and implemented a CUDA-based parallel computing program to calculate 3D spatial distance histograms from large point cloud datasets. Optimized memory usage and computation time by leveraging GPU shared memory, minimizing global memory access, and using warp shuffle instructions for efficient reductions.

Skills Used:
CUDA, C++, Parallel Computing, GPU Optimization

3. AWS Cloud Infrastructure Deployment (Self-Study Project)

4. Big Data Processing with Hadoop

Fall 2023

Description:
Processed advertising campaign datasets using Hadoop MapReduce jobs written in Java. Imported relational data into HDFS using Sqoop, and performed data transformations using Apache Pig scripts. Analyzed and visualized ad campaign performance trends through large-scale ETL workflows.

Skills Used:
Hadoop, MapReduce, Java, Sqoop, Apache Pig, Big Data Analytics

Fall 2023

Description:
Built and deployed a JavaScript and HTML5 web application on AWS cloud infrastructure. Configured EC2 instances, S3 buckets, RDS databases, IAM roles, and Auto Scaling Groups. Focused on creating scalable, secure, and highly available systems with load balancing and monitoring.

Skills Used:
AWS (EC2, S3, RDS, IAM), Cloud Architecture, Web Hosting, Auto Scaling

5. InkRhythm Nail Website (Shopify Project)

Summer 2023

Description:
Developed and launched a fully responsive Shopify-based e-commerce website for a fictional nail studio. Customized the site using HTML, CSS, and Shopify’s Liquid templates, focusing on modern UX/UI design and mobile accessibility.
(Note: This project website is no longer active.)

Skills Used:
Shopify, HTML5, CSS3, Liquid, UX/UI Design, Responsive Web Development
