About me

Hi! 你好! 👋

My name is Steven Lio. I was born in Hong Kong, China and grew up in Macau, China. I moved to Canada in 2007 and currently living in Toronto, Ontario.

I received my Master of Data Science from University of British Columbia (Canada) and my Bachelor of Science degree in Statistics from McMaster University (Canada).

With over 7 years of professional experience, I specialized in developing data-driven solutions and workflows to extract actionable insights that support strategic decision-making for cross-functional teams in Government, Telecom, Retail and Software industries. I possess a natural curiousity and a keen eye for detail when analyzing data, enabling me to find the optimal solutions for finding data-driven solutions and drive business decisions.

Proficient in Python and R, I excel in creating end-to-end machine learning workflows for complex data science projects. My expertise spans developing efficient data pipelines, performing feature engineering, implementing machine learning models and building interactive visualization applications. Like this one here.

I have applied practical machine learning to real-world challenges across classification, clustering, statistical inference, regression and time series modeling, delivering actionable insights to support data-driven decision-making. I have also developed advanced models, including CNNs for image classification and segmentation and computer vision task (Object detection, Segmentation, Classification etc.).

More recently, I have worked on LLM-based and Agentic AI systems, designing and building multi-agent systems with tools like Google ADK, DSPy, and LangChain. Creating interactive applications for Human-In-The-Loop model training etc.

Additionally, I am skilled in SQL for large-scale data processing, ETL pipeline design, feature engineering, and ensuring data quality and integraity for complex datasets..

My advanced data analytics have supported marketing strategy research in areas such as Predicting Customer Value, Customer Segmentation, Sentiment Analysis, Market Potential and Shares Estimation, Competitor Analysis, Optimizing Sales Channels. Leveraging hypothesis testings (A/B Testing) to help steer software development directions for UI/UX and model performance.
