PingMe Google Software Product Sprint
A web application that builds a bridge between minority groups and those who love to help. Users can report emergency situations or request non-emergency assistance. Users nearby can then see the reports on map and help out those in need. This is helpful for people who are physicaly disabled or under threat to dictate emergency situation over 911.
Features
- Report emergency situations with location by one tap.
- Request non-emergency assistance with location by a HTML form.
- Visualize nearby requests on Map with location and messages.
- Options to offer assistance or contact the requester for more details.
ColbyEat
Personal MERN Full Stack Project
ColbyEat is a full stack MERN web application that gives a better experience of checking dining menus. It scrapes the raw and ordinary dining hall menu and notifies users of daily menu in a beautiful text message. It allows users to store dietary and location preferences so that they can receive notifications of dish items that fit their preferences.
Features
- User can sign up and log into the application with Email.
- Setup profiles with meal and dining hall preferences.
- Receive text message of daily menu based on preferences.
- Options to adjust notification time and frequency.
Checklist CodeDay Labs
A full stack web application that gives better experience in automated checklist creation. It allows users to create checklists from templates with customized inputs. It also allows users to share their checklists with others. All data are secured in MySQL database.
Features
- Fast response time using RedwoodJS for full stack.
- Create checklist from a template.
- Manage, edit checklists in modern user interface.
- Secure sharing of checklists.
Java IDE
Object Oriented Design Course Project
A multi-platform Java Integrated Development Environment for editing and compiling Java source code. Developed following the MVC and Object Oriented Design principles by a group of 3. Apart from supporting the following useful features, it also integrates our own implementation of Java compiler and standard input/output.
Features
- Supports find & replace, toggle comments, bracket matching
- Integrates pretty print formatting and automatic syntax hightlighting
- Compiler and error checking & standard input/output on Terminal
- Includes our implementation of tokenizer, parser, semantic analyzer
Eye Movement Biometrics
HCI Research Project
Eyes, the passwords to your devices -- by combining eye movement data during natural text reading with cognitive and linguistic features, I build supervised learning pipelines that improved the accuracy of eye-movement biometrics from 60% to 73%. Results are published in ACM Symposium on Eye Tracking Research and Application 2022 (Best Technical Abstract Award).
Outcomes
- Utilized OpenCV, random forest and neural network to identify users
- Trained supervised machine learning models and built pipelines
- Improved the accuracy of biometric identification to 73% by using a combination of textual data and cognitive factors
.experience()
With strong experience in Python and data science, I was selected in freshman year to conduct one-year CS research. With fruitful results in eye movement biometrics, I discovered my profound passion for software development. Since then, I've been learning and working on web technologies, and used my creativity and skills to built projects that help people live better with technology.
