01 / ABOUT ME

More than
the code I write.

I'm TangJin, from Taiwan, with roots in Hsinchu City, Hsinchu County, and Taipei. I enjoy solving problems through code and stepping out into the world to find new perspectives.

I'm an engineer and an investor. Curiosity, exploration, and the determination to keep going are what move me forward.

05 / FUTURE — THE HOME

A company to build.
A home to belong to.

By “home,” I don't mean a house. I mean a company I build: a place where I belong, and where others can belong, too.

I have plenty of ideas for software and online services. The challenge is finishing one before the next arrives. I want to keep learning and connect with people who can help bring those ideas to life.

Excellent idea generation. Project management? A work in progress.

01 / THE PRODUCTS

Make everyday life easier.

Build useful software and convenient online services that make people happier. Ask for a small amount in return, and earn it by making something worth using.

02 / THE PEOPLE

Trust people. Make room to care.

Create a place where people are trusted and can work on things they care about. A company built on shared purpose, with room to choose how we work.

One day, I hope to build a company that feels like home—for myself and others.

With a very small entrance fee.

“I will never give up, though there is still a far way to reach home.”
TangJin.

06 / LET'S CONNECT

Every connection
starts with hello.

Let's talk code, exchange ideas, or explore what we could build together.
