Frody
Frody is a microservice on the Google Cloud Platform that uses machine learning to flag and inform users on real-time transactional data. The user can "subscribe" to the transactional activities for multiple cards on a centralized dashboard, where they can monitor their transactional activities. If suspicious activity is detected with Frody's fraud detection model, the users will be informed via text message immediately.

susTrip
SusTrip is a full-stack web application that records users' past trip information and respective carbon footprints. It aims to help users think more carefully about the mode of transportation they wish to take. Users will input the mode of transportation and the distance that they travel, and the program will output the amount of CO2 produced from that trip. Users can also create an account to track their trip history through a personalized dashboard that provides an analysis of their carbon emission footprint.

Royalty NFT Smart Contract

Royalty NFT Smart Contract
Awarded first place in HoyaHacks 2022 Gear Technology Track for creating an NFT Smart Contract that allows users to mint NFTs that enable percentage return to the original creator and deploy them on a Polkadot Parachain. In this world where there are many circulations of fake and unoriginal work, we believe that our smart contract encourages creative thinking and inspires original ideas. Our smart contract allows the original creator of the NFT to receive a certain % of transaction payment as a type of "royalty". Deployed in Gear Technologies' cutting-edge blockchain network, our smart contract allows its users to mint, exchange, and receive a royalty on their NFTs without much effort.
