Third-year CS student at UC San Diego (GPA: 3.53 | Regent's Scholar | Alan Turing Scholar) studying the intersection of software engineering, machine learning, and human-centered design.
I build things end-to-end — from React frontends to REST APIs to LSTM models. Currently looking for Summer 2026 SWE internships.
Study Buddy — AI-powered flashcard & quiz generator
React · FastAPI · MongoDB · Google Gemini
Upload a PDF, get a full study set. Built in 24 hours at a hackathon with a 4-person team. I owned the frontend — responsive UI, dynamic flashcard/quiz components, study pack creation flow.
Fast Food Voting Analysis — ML model predicting 2024 state election outcomes
Python · Pandas · scikit-learn · BeautifulSoup · Selenium
Wrangled 12 datasets, engineered per-capita franchise density features across all 50 states, hit 0.81 average accuracy. Built automated scrapers with SSL handling for reproducible data collection.
Audio-Based HAR System — Research @ UCSD CSE
Python · PyTorch · LSTM
Novel audio-labeling pipeline for human activity recognition data collection. Cut annotation time by 70% and hit 81% validation accuracy — beating button-based (56%) and WISDM (62%) baselines.
