Lingli

I'm a 16-year-old based in Singapore who spends most of my time making things — whether that's software, music, businesses, or just figuring out how stuff works.

I started building and selling self-built PCs in 2024, taught myself to code by solving real problems, and developed a serious passion for classical piano and video production along the way. I'm not great at sitting still.

Right now, I'm in HCI JC1, building a productivity app, exploring finance, and trying to get better at everything I'm not good at yet.

Why I Build

Most of what I've built so far has been for myself — to solve my own problems, make money, or just because I was curious. But the older I get, the more I realise the most interesting work is building things that create impact beyond yourself.

That's the direction I'm heading.

What I've Built

Electronics Trading — Carousell

Started flipping self-built PCs, keyboards, earphones and consumer tech on Carousell. Learned pricing, buyer psychology and logistics the hard way. Generated thousands in sales across multiple product categories.

Aeroponic System — Sec 4 Project Work

Designed and developed a commercially viable aeroponic farming system concept aligned with Singapore's 30x30 food security plan. The national initiative was later discontinued.

ZB Schools Automation

Wrote a script that got me to 3 million points on ZB Schools while most users sit at a few thousand. Small project, real result.

E-Commerce Attempt

Tried selling physical goods online — hot water bags, food products. It didn't work out. Learned more from this than most things that did.

Failed. Worth it.
