LOUIS YU
Surviving on data viz, coffee and video games

Like an avid gamer I am, I obtained more skills over my career years such as SQL, Python, Power BI and most importantly... Tableau.

But I had grown really fond of telling stories, sharing insights and teaching others how to do the same. And maybe it's also heavily inspired by role-playing video games, which has shaped most of my life.

So stay a while and listen to me ramble on everything
data visualization, design and video games.

Technology is always advancing and while I was proud of what I could achieve in Excel many years ago, it's worth much less in today's context. But what kept me going all these years, is the constant drive for self-improvement and my curious mind.
