ABOUT Me :>

2nd Year Engineering Science student at the University of Toronto focused on medical and health sciences using tools from Computer and Electrical Engineering.

  • Experiences in 3-D modeling and simulation, machine learning, and front-end development
  • Curious about Neurobiology & medical instrumentation
  • Open to collaborations & researches on healthcare technologies

Engineering lives between what is and what could be. I seek rigorous engineering with a practical mindset: simple, testable, and maintainable. I focus on health science because trailblazing in this field is a direct way to improve people's quality of life.

Engineering always lives with uncertainty. In this career, become a pessimist who maps all the risks as well as an optimist who acts—read the sky for storms and set sail.

Pessimists are always right, while optimists always move forward.

PROJECTS (^_^)

PPG preview

Photoplethysmogram (PPG) Heart Rate & Variability Monitor

2025 · May -- August

Real-time PPG Signal Processing Web & Mobile Streamlit App

  • Upload a simply-recorded live video for PPG analysis.
  • Obtain heart rate and variability metrics in real-time.
  • Provides a predicted cardiac rhythm and alerts for potential issues.

Improving Clay Reclamation

2025 · February -- April

Together with a Praxis Team, partnered with stakeholder Anne Gibson from Kalon Ceramics, Toronto, understood the operational limitations in small studio clay reclamation and developed a small-scale automated pugmill system of mechanical mixing and contaminant filtration.

COVID Stats

COVID-19 Cases Visualization

2024 · February -- June

A mentor-research project worked with Dr. Stephanie Black, New Hampshire University, created a data visualization dashboard for COVID-19 statistics and provides forecasts based on previous trends and density.

AI Autocomplete

2025 · January -- February

An autocomplete system using machine learning ideas to predict user input. It loads a text file of (weight, term) pairs into memory and sorts the array lexicographically by term once at startup. Then use binary search to find the lowest and highest indices that match the prefix and copy that slice and sort it by descending weight to produce final suggestions.

Seamcarving preview

Seam Carving

2025 · March -- April

Seam carving is an image processing technique for content-aware resizing. This project implements seam carving in C: it computes per-pixel energy from image gradients, uses dynamic programming to find the minimum-energy vertical seam, backtracks the path, and removes it to reduce width by one pixel.

synonyms preview

Semantic Similarity & Synonyms

2024 · November -- December

This project builds a semantic descriptor for each word: a dictionary counting how often other words co-occur with it in the same sentence (from your training corpus). Then compares words by cosine similarity of those vectors. The starter spec describes this pipeline and the cosine metric.

gomoku preview

AI Gomoku

2025 · October -- November

A Gomoku game that uses basic machine learning techniques that allows a user to play against the computer (AI). The computer will examine all possible moves and choose the best one based on the current board state.

EXPERIENCES

2025 July — Present

Co-founder & Chief Technology Officer (CTO)

Spark Learning Inc. (sparklearning.ca)

Co-founded a startup focused on providing personalized mentoring and academic planning services for high school and university students. I designed the operating model, trained new mentors, and led the platform's technology. These included but not limited to designed a privacy-first autoscheduling system and the official website.

Interpersonal skillsLeadershipFront-end
2021 September — 2024 June

President, Head-Instructor

Computer Science & Digital Media Club

One of the largest school STEM clubs, divided into two portions: Computer Programming and Website Design. I held lectures on Java and Python, guided members to understand coding structure and programmed mini-games. Created mock AP exams and help sessions regularly when approaching an exam or competition.
