A little about Kongwei Ying

I create deeply useful software tools for people.

I do this through my professional and personal experience as an entrepreneur, software engineer, designer, and marketer.

I have an interest in theology, self-realisation, meditation, metaphysics, philosophy, history, psychology, biomechanics, biology.

My current focus

Building Natural Scientific Calculator 2 - A second version of a scientific calculator I created many years ago
Building Filtrum - A browser that precisely filters out negativity on the web
Building Kairos Lifemap - A lifemapping tool that visualises the past, present and future

I primarily live in Sydney, with periods of the year spent in Shanghai.

I freelance as a software engineer and help people and businesses build their own tools and apps.
I share my insights and shed light on subtle dynamics that I've seen impact my own and other people's lives time and time again. You can read them below.
My tools are intended to deeply and personally help your life.

现德經 - Xian De Jing - Treatise of the Modern Age

Many years ago, I created, designed and marketed Natural Scientific Calculator which got over 1 million downloads organically.
I interned at Google and Microsoft, in both marketing and software engineering divisions respectively.
I later received offers to work as product manager and software engineer from these big tech companies. I declined these offers to pursue my own more well-rounded path of development outside of the pigeonholing associated with traditional roles.
I also ran a small software consultancy that built apps for various businesses and startups, where I worked with my university friends.
