About
I'm currently studying Computer Science and Business Administration at USC✌️ in sunny California. My passion for programming began with game development in Unity and has since evolved into a love for building web and mobile applications. In my spare time, I love spending my time at the thrift, staring at JDM cars, and daydreaming of vintage tech.
Work Experience
Skills
Check out my latest work
I've built a variety of projects exploring various technologies, from mobile apps to web applications. Here are some of my favorites.

Sage
Led the development of Sage, an innovative legal workbench with advanced document retrieval, case management, and an AI-driven assistant. Improved workflow efficiency by 40% and reduced manual workload by 35% using machine learning and Retrieval-Augmented Generation (RAG).

Azalea
Azalea helps users choose eco-friendly AI models by rating their energy use and complexity. It provides a sustainability score and impact metrics, such as plastic bag equivalents. Azalea also tracks and compares the environmental impact over time.

Octavo
Octavo is a human-centered search engine powered by shared Letta memory agents that taps into the lived experiences of many to answer complex, nuanced questions better than Google ever could. Instead of indexing static web pages, Octavo creates a collective intelligence hive from real human memories and experiences.

Guildhall
Built Guildhall, a gamified iOS productivity app that transforms habit-building into a collaborative RPG experience. Developed animated pixel-art guild halls using SpriteKit and integrated Firebase and OpenAI APIs to rank task difficulty and sync real-time guild data.
I like building things
Currently, I have attended 9 hackathons (and counting). I love the atmosphere and taking an idea from 0 to 1.
