Interests
Apart from software development, I enjoy spending time with my dog, taking a walk or a hike in the cooler months of Hong Kong.
Otherwise, when on the computer, I am almost always checking up on the latest news of blockchain and cryptocurencies, as I am heavily invested in blockchain projects. I do a little bit of swing trading when the market goes through their natural cycles.
