Wei-Lun Li — Software Engineer in Tokyo

01 — About

A career across four industries

I'm a Taiwanese software engineer based in Tokyo, with a master's degree in Information Management (major in Human-Computer Interaction) from National Taiwan University.

My work has covered a lot of ground: backend services in MarTech, enterprise technical solutions across Web / Android / iOS, cloud security and vulnerability assessments, and NAND Flash applications in the semiconductor industry — everything from building software to standing right next to the people who use it.

That mix taught me both sides of technology: how it's made, and what happens when it meets the real world.

Off the clock you'll find me on a basketball court or in a movie theater.
