2019 – End of Year

2019 was quite a busy year for me. I haven’t been updating my blog much due to a lack of time and energy, but I’ve done a lot of personal projects that I’m really proud of and I think pictures and short captions do these projects enough justice. So here it is, my 2019 whirlwind year in review.

I competed in Battlebots as the captain of Team Uppercut, where my team finished in the top 16 after losing to the eventual champion, Bite Force.
