Highlighted Projects

Showcasing impactful projects that demonstrate my skills and insights in fintech and social innovation.

AMD Stock Analysis Dashboard

Time Series Analysis on AMD Stock Prices

Conducted a comprehensive analysis of the influence of news sentiment on AMD stock prices from 1984 to 2024. Utilizing time series techniques, I examined 159 daily observations and 473 monthly observations, revealing significant predictive relationships. The findings indicated that daily news sentiment had a stronger impact on stock returns than annual report sentiment, with the 7-day moving average emerging as the most important predictor for forecasting stock prices.

Airbnb Market Analysis

Airbnb Listings Analysis

Analyzed two Kaggle datasets comprising 458,177 Airbnb listings from 2020 and 2023 to assess the impact of the COVID-19 pandemic on the rental market. The analysis revealed average prices between $200 and $300 per night and identified the most booked unit types, providing crucial insights for potential investors looking to navigate the recovering market.

P2P Lending ML Model

Machine Learning in Peer-to-Peer Lending

Developed predictive models for optimizing loan investments in peer-to-peer lending, analyzing over 1.8 million loans worth $15 billion. The project identified a 13.5% default rate and interest rates ranging from 6.7% to 22.8%. I implemented three return calculation methods, finding that the optimistic method yielded the highest returns, albeit with increased risk. This project demonstrated the effectiveness of data-driven strategies in investment decisions and confirmed that recent data models consistently outperformed random selections.

Kit Star Aquaponics

Kit Star - #DeisHacks2023

Kit Star is a custom shipping containerized aquaponics and organic vertical farm solution. This project creates a symbiotic relationship between fish and plants, reducing waste and producing fresh, healthy produce. The vertical farm setup optimizes the use of space within the container, maximizing harvest potential and providing a sustainable food production system.

The inspiration for Kit Star came from the challenges faced by The Land's Sake Farm and similar organizations in sustainable agriculture. We aimed to address limited space and resources while revolutionizing their operations.

One of the biggest challenges was creating a sustainable closed-loop system between the fish and plants. We learned the importance of optimizing space while ensuring a healthy environment for both.
