01 — Profile
Driven by data,
built to ship.
I'm a Data Science undergraduate at San José State University (4.0 GPA, Class of 2026) who lives at the intersection of analytics and engineering. Whether it's predicting heart-attack risk with machine learning or wiring up a voice-activated AI assistant, I like turning messy data and rough ideas into things people can actually use.
Right now I'm interning as a Software Engineer at Twinly while running data analytics at IDX Exchange and improving learning platforms at Knodemy. My toolkit spans Python, Java, SQL and the modern web — backed by a Google Cybersecurity Professional Certificate and a stubborn habit of shipping.
When I'm not building, I'm teaching: mentoring young developers at All Star Code and running robotics curricula for the next generation of makers.

Things I've built
AI · Open-Source Fork
TARS
A modular voice-activated AI assistant I work on — wake-word detection, Whisper speech-to-text, text-to-speech output, real-time voice chat, a tunable personality engine, and RAG-based memory backed by ChromaDB.
Machine Learning
Heart-Attack Likeliness
An ML pipeline that predicts heart-attack risk from health and lifestyle indicators — combining exploratory data analysis of risk factors with trained classification models for individual risk assessment.
Full-Stack
ProblemPad 2.0
A problem-report tool with a vanilla JS frontend and a Flask + SQLite backend (Dockerized), with graceful localStorage fallback when the API is offline.
Data Analytics
IDX Exchange Analytics
Real-estate analytics tied to my IDX Exchange work — turning raw MLS/IDX feeds into structured datasets and KPI dashboards that track pricing and inventory trends.
Python · CLI
BookBot
A Python command-line tool that parses a book and reports text statistics — word counts and character-frequency analysis.
Web App
ProblemPad
The original problem-report template — a lightweight static web app persisting entries to the browser, the foundation that ProblemPad 2.0 grew from.
Frontend
Portfolio
An earlier hand-built portfolio site — my first dive into crafting layouts and responsive design from scratch with HTML and CSS.
