Hello, and welcome to the index —

I am Sofia Kung, a data analystproduct managerAI product builderfraud fighter.

§ 00 · Introduction Singapore · 2026

Senior data analyst turned AI builder. Based in Singapore.

After six years across data analytics, fraud & risk strategy, and consulting at Binance, Gojek and PwC — being the person who spots risk and deploys solutions before damage compounds — I took a deliberate step back to ask what was worth building next.

I spent the past months going deep: AI automation, web apps, agents — taking ideas from zero to product. I've always wanted to build.

Now focused on where it all converges: AI adoption that drives business outcomes, underpinned by the observability and risk thinking that makes it sustainable.
