Enabling REDCap as a Tool for Multimodal Video-Labeling Research

A Novel Workflow for Crowdsourcing the Labeling of Extensive Multimedia Content

The capabilities of REDCap as a research survey tool are well-established; however, challenges arise when attempting to dynamically embed video segments involving varied video lengths for crowdsourced ground truth labeling. To address these challenges, we integrated REDCap with Amazon AWS and a content delivery network, extending REDCap's functionality for efficient video handling and scalable data collection through Amazon Mechanical Turk. This integration enables REDCap to effectively manage a segmented video library, supporting dynamic streaming and labeling at minimal cost. This methodology extends REDCap’s utility for extensive data analysis and broadens its application across multimedia research settings.

LeukApp: Decision Support Web App

React App Usability Testing and Technical Revisions for HonorHealth

LeukApp is a clinical decision support web application designed to assist physicians in the risk assessment and treatment of acute myeloid leukemia. My role in this project involved evaluating LeukApp's usability following third-party development and implementing necessary modifications or enhancements to optimize its functionality. This project was a collaborative research effort between ASU and HonorHealth, aimed at aiding physicians' decision-making and resident training.

I was a presenter for the LeukApp project at the AMIA 2019 Annual Symposium, where it was well received during a productive poster presentation session. Through my user testing with oncologists, fellows, and clinical administrators, I gained valuable insights into the importance of usability and UI/UX testing for ensuring end-user satisfaction and effectiveness in healthcare applications. This experience underscored the critical role of user-centered design in the development of clinical decision support tools.

BankFolio

Fintech iOS Mobile Application for Personal Finance Management

BankFolio is an app I bootstrapped using Apple's native SwiftUI and Swift, leveraging the Plaid API to retrieve and display user bank account information and accompanying transactions in one place. The idea came about when I got charged for subscriptions I forgot I had signed up for and wished there was an easier way to spot those transactions quickly. After discovering Plaid's API and doing some research, I found apps offering this service for an average price of $6 a month, which seemed overpriced. The target audience for this type of application is looking to save money rather than spend it. Therefore, I decided to provide this app to users at a near net operating cost based on their number of connected accounts so more people could take advantage of these features and control their hard-earned money.

In 2022, BankFolio underwent an unsuccessful acquisition that adversely impacted the company's financial health, primarily due to the integration of costly services, such as MX Finance, without corresponding marketing strategies initiation.
