About Me

Hi, I'm WeiEn Weng. I'm the founder of Teyra LLC, a software company that builds apps and API services. My work sits at the intersection of clean engineering and thoughtful product design.

I started coding because I loved solving problems. I started a company because I wanted those solutions to actually reach people. Every product I build — whether a polished iOS app or a developer API — is an attempt to make something genuinely useful.

When I'm not building, I'm exploring new technologies, attending developer meetups, or contributing to open source.

Principles

Ship fast

Done is better than perfect. Real feedback beats speculation every time.

Quality matters

Speed without craft is debt. I care about both the code and the experience.

Build in public

Sharing work early creates better products and stronger communities.

Keep learning

The best builders never stop being curious. Technology moves fast.
