NVIDIA Stock Returns Prediction with LSTM

An advanced stock price prediction model for NVIDIA using Long Short-Term Memory (LSTM) neural networks. Incorporates financial time series data alongside sentiment analysis from news articles leveraging transformer-based NLP models. Features data preprocessing, model training with TensorFlow, and interactive visualization using Streamlit and Plotly. Demonstrates deep learning for time series forecasting, NLP integration, and end-to-end deployment of finance AI applications.

Midas Core Financial System

A high-throughput financial transaction engine developed during a JPMC Software Engineering program. The system processes real-time financial data using Apache Kafka for asynchronous message handling and ensures data integrity through a SQL database (H2/JPA). Features include automated transaction validation based on user balance and ID verification, a decoupled REST API integration for dynamic incentive calculation, and a GET endpoint for real-time balance queries. The project leverages Spring Boot's dependency injection and embedded Kafka for robust, scalable backend performance.

League of Legends Team Balancer

A custom League of Legends analysis and team balancing tool. Uses each player's score in every role across game types such as normals, ranked, and swiftplays. Creates FIFA card-style player stats for each player, and uses algorithm that minimizes skill disparity across roles for fairer matches. Features a modern React frontend on Vercel, FastAPI backend hosted on AWS, PostgreSQL data storage in Supabase, and a team balancer that leverages historical match data for optimal team composition.

A LITTLE CONTEXT

About me.

I’m a University of Washington Seattle student in the Class of 2027, studying software engineering and data science. I love logic puzzles, exploring new ideas, and the games I grew up with—from Minecraft and Skyrim to Stardew Valley. I’ve always enjoyed bringing ideas to life, whether in a game or in code.
