Electrical Engineering student at UCLA interested in electronics, machine learning, and software development.

Projects

A transistor-based oscillator with an RC-filtered output that drives a passive buzzer. A potentiometer and two timing switches adjust the pitch. Holding a button fades the buzzer and LED through a separate RC envelope. Includes an LTspice model and a PyTorch CNN trained to read the control positions from photos.

Collects public internship, research, program, and event listings, tracks changes, and screens leads against a profile. A searchable dashboard supports reviewing leads and tracking applications. Users can use their own AI agent to investigate eligibility and prepare drafts from profile information and source documents in a private workspace.

A Windows app for transcribing audio and video files and dictating text. Offers optional AI cleanup for wording and punctuation, formatting as prose or structured notes, and shorter study-note summaries. Preserves the original transcript alongside cleaned and formatted versions, with playback, editing, search, and export. Works offline after model download.

A health-coaching project for predicting daily readiness and energy from wearable measurements and daily check-ins. Includes data storage, sleep scoring, and an evaluation workflow designed to compare individualized predictions with historical baselines and Google Health Premium insights.

A kit for running coding agents in disposable Docker containers from WSL. Supports Codex, OpenCode, and Claude Code, with read-only Git metadata and separate agent logins. Includes folders outside the repository for read-only reference files and saved work.
