SC
Things I've Built
Video Game Finder
A Dockerized multi-layer backend API that allows users to interact with a database of the best selling PlayStation 4 games. The API also handles authorization and privileges via a JWT validation system.
Bayesian Network Financial Notifier
A Bayesian Network trained on financial data and alerts that is able to classify monetary notifications based on priority level. This includes transcations, statements, financial news, investments, security alerts, and more. The network returns summary of the classified data and also has a built-in interactive mode so users can feed it their own financial notifications.
FromToDivisible
A program that solves the TopCoder problem FromToDivisible. Applies graph theory and specifically a breadth first search algorithm to find the shortest path to get from a starting number to a target number, where each step must be divisible by a given divisor.
LeNet Model PGD Attack
This program takes a LeNet model with an adam optimizer, trained on the MNIST dataset and applies a Projected Gradient Descent (PGD) attack to generate adversarial examples. The PGD attack is evaluated every 10000 examples by analyzing the model's accuracy and comparing it to the original model. Specifically, the program iteratively tests how the models preforms when the hyperparameters of the attack, including the epsilon and iterations, are altered and pipes all results to a CSV file for further visualization.
Hangman
A program that implements the classic Hangman game in Java. Features include user input handling, a visual representation of the letters guessed, a tracker for the number of limbs remaining, and error handling for invalid or repeated guesses,
Software Engineering Intern
Transcard · Chattanooga, TN
Led the development of a production full-stack dashboard spanning four repositories that provides employees with centralized visibility into millions of payables. The application transformed a previously manual, ticket-driven investigation process into a secure self-service platform used daily across four departments while giving me experience designing enterprise software across the frontend, backend, database, and deployment pipeline.
- Led development of a production full-stack dashboard spanning four repositories, reducing payable lookup times from 5–10 minutes to seconds across four teams.
- Designed and implemented 14 full-slice REST API endpoints, including cross-database integrations using C# and .NET Framework.
- Authored 43 production pull requests across frontend, backend, and database layers.
- Implemented a secure payload decryption workflow while balancing PII protection, security, and usability requirements.
- Presented the application to employees, engineering leadership, executives, and end-user teams, including an additional demonstration requested by the COO.
- Participated in production deployments and multiple UAT database and application releases through Azure DevOps.
- Collaborated with business development teams to onboard analytical tools and translate complex data into business opportunities.
Backend Software Developer Intern
Datably · Chattanooga, TN
Returned to Datably to continue developing production software while expanding my responsibilities
beyond feature development into application maintenance,
production support, and backend infrastructure. This experience strengthened my ability to troubleshoot enterprise systems,
implement reliable backend services, and collaborate closely with senior engineers.
- Developed backend services to register client applications with company infrastructure, enabling automated backups and health monitoring through REST APIs.
- Completed production support work including security fixes, dependency updates, bug resolution, and code refactoring.
- Collaborated with senior engineers to troubleshoot production issues, implement enhancements, and improve enterprise software reliability.
- Presented technical contributions to engineers, employees, and company leadership.
Backend Software Developer Intern
Datably · Chattanooga, TN
Began my software engineering career by contributing to enterprise backend
systems while learning professional software development practices.
I gained hands-on experience with production code, collaborative development,
and backend architecture while making meaningful contributions across multiple large-scale projects.
I was later nominated by Datably for the Chattanooga Technology Council's Emerging Tech Student Award and had the privilege
of being selected as the recipient of the award in September 2025 (See below).
- Authored 10+ production pull requests across multiple enterprise applications.
- Implemented an outbox execution tracker to improve execution monitoring and message processing.
- Worked across large enterprise projects while learning professional QA, code review, and software development workflows.
- Presented project contributions during three engineering reviews with developers and company leadership.
- Built experience with PostgreSQL, PgAdmin, Git, Docker, and the .NET Framework.
