Hi, I’m Harry — a data professional with a strong track record in both the advertising/media and healthcare industries.

I began my career as a Data Scientist in the media world, working with large-scale telco location data from over 30 million devices daily to drive marketing insights and business impact. Later, I transitioned into healthcare as a Lead Data and System Analyst, where I focus on architecting a centralized data warehouse (our “data map project”) to support complex hospital business lines and operations.

What I Bring to the Table
Industry Range: From fast-paced media campaigns to mission-critical healthcare systems

Technical Depth: Strong in data architecture, system integration, and end-to-end analysis

Problem-Solving Mindset: I enjoy spotting hidden issues, debugging the unexpected, and identifying challenges others may overlook

Big-Picture Thinking: I don’t just look at data — I aim to design systems that scale and empower smarter decisions

What You’ll Find Here
This site is a space where I share my thoughts, lessons, and projects on data, systems design, and AI — from technical write-ups to behind-the-scenes problem solving. If you’re interested in the messy, meaningful, and sometimes magical world of data, I hope you’ll find something here that resonates.

Thanks for stopping by — and feel free to connect if you’re working on something interesting or just want to talk data.
