Founder, developer,
relentless builder.

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.
