projects
A ultra lightweight harness TUI for coding agents using all available OpenAI models (and more) at only 8MB in total size. Uses a MCP server hosted via Vercel sporting 70+ robust tools aiming to maximize how much an agent can do while remaining as responsive as ever. Made at Jetbrains x Codex Hackathon.
A multi-model coding agent integrating Perplexity web search. Engineered to use as few tokens as possible making project generation and completion extremely cost effective. Average project per prompt costs less than 10 cents per generated project. Winner of HackHayward 2026.
A GraphRAG Research QA Platform for users to interact with Neo4j knowledge graphs optimizing long-context LLM performance and reducing hallucinations. Tested and benchmarked to used up to 75.5% less tokens when compared to other GraphRAG frameworks. Uses PolyG.
An visual speech recognition/lip reading engine and application for identifying speech patterns for audibly impaired individuals. Integrates MediaPipe and OpenCV for webcam capture, video analytics, and facial overlays. Uses PyTorch and deep learning reinforcement./span>
A robust Java app that curates user generated content and study sets to accommodate personalized learning pathways with interactive review and assessments.
MYLogin is a lightweight security utility TUI written in Python and Go that allows for convenient storage and retrieval of login information with multi-layered encryption.
An automation tool for Git workflows and GitHub written in C and Bash.
A portable and compact math library written in C/C++ for working with matrices and numerical algorithms.
about
As a highly driven fourth-year studying Computer Science at Cal State East Bay, I am deeply passionate about the rapidly evolving world of Artificial Intelligence and Machine Learning.
My completed coursework includes: Data Structures and Algorithms, Object Oriented Design, Operating Systems, and Computer Networking. I aspire to break into the AI sphere as a full-fledged ngineer and use my skills to develop innovative solutions to real world problems.
