CS & Philosophy Major @ Cornell
About Me
Hello! I'm Yaelin, a Computer Science and Philosophy double major at Cornell University.
I love to create — whether that's building products that help people or writing stories and songs. I love to learn new technologies, working across full-stack web, AI-powered tools, IOS apps, and VR systems. I'm especially interested in intelligent systems and human-centered design, always trying to emphasize clean architecture, user experience, and real-world impact in everything I build.
When I'm not coding, I'm probably playing the guitar with my band, writing, or listening to music.
Experience
The Widget Factory (Idler YC S25)Analyze production code across unfamiliar repositories to design coding problems for AI training datasets. Evaluate task clarity and solvability to ensure problems are answerable using only the provided context. Write technical rationales identifying ambiguous requirements and missing implementation details.
Cornell WebDevDesigning and developing custom websites for Cornell organizations. Creating responsive UI mockups in Figma and implementing accessible, maintainable frontend components using HTML, CSS, and JavaScript.
Cornell XRDeveloped multi-user VR features for architectural model review, including annotations, lighting controls, scaling tools, and real-time communication systems. Currently building custom Unity environments to integrate with an external olfactory device, expanding immersion beyond visual and spatial interaction. Across all features, we prioritize accessibility, usability, and inclusive design to ensure collaborative XR tools are intuitive and widely usable.
FendodoProvided individualized instruction in standardized test preparation and AP English Literature, focusing on analytical writing, reading comprehension, and test strategy. Helped students build confidence, structure arguments clearly, and improve measurable score outcomes.
Projects
Developing an iOS app that acts as a behavioral and safety layer for nights out.
Built a production-ready Chrome extension that converts natural language into structured Google Calendar events. Developed a secure server-side LLM pipeline to prevent client-side API exposure, implemented OAuth 2.0 authentication, and integrated the Google Calendar REST API to create a seamless end-to-end event creation workflow.
Collaborated in a 3-person team to design and implement a 1,700+ line chess application from the ground up. Engineered a complete rules engine supporting legal move generation, castling, en passant, promotion, check/checkmate detection, and game termination logic, paired with an interactive graphical interface.
Collaborated on a multi-user VR application that enables architects, designers, and clients to collaboratively review architectural models in real time. Features include live annotation tools (drawing + typed notes), voice communication, laser pointer tracking, adjustable model scaling/zoom, a mini-map for spatial awareness, and dynamic lighting controls for day/night simulation.
