About Me

A Developer with Passion for Innovation

Hi, I'm YANG JIZHOU — you can also call me Haruka / 悠.

I am a full-stack developer with a deep passion for crafting elegant and efficient digital experiences. I love transforming creative visions into reality through code.

My journey began with a curiosity for technology, evolving into a relentless pursuit of innovation and excellence. I explore the intersection where technology meets artistry.

When I'm not coding, you'll find me exploring emerging technologies, reading, or contemplating my next creative project over a cup of coffee.

First Taste of AI

The day AI first truly clicked for me — and the world stopped looking the same.

2025.12.28

AI Belongs to Everyone

It finally clicked what AI is really for — reaching the ordinary people and traditional industries who don't yet understand it, but stand to gain the most.

Becoming an FDE — sitting with real users, turning fuzzy needs into things that ship. Let's see how far this goes.

What's next

Practical AI for the industries that keep everyday life moving.

My long-term hope is to make AI useful in traditional industries: less repetitive work, smoother processes, and more time for people to do what matters. Healthcare is a direction I would especially like to keep exploring.

Understand the real workflow

Keep growing toward an FDE role: learn how people work in restaurants, retail, and other traditional industries, then stay involved from the first conversation through delivery and use.

Make the improvement count

Focus on time saved, fewer manual steps, and fewer errors, with evaluation and recovery built in so the improvement lasts beyond a demo.

Keep exploring healthcare

Build on my medical-imaging experience through further learning and collaboration, exploring assistive tools and workflow improvements that leave professionals more time for people.
