About

Hi! I'm SanguineChameleon.

This is my website, where I write about whatever I like, whenever I like.

Personal Details

This section is here for you to decide whether or not I'm qualified to say what I say.

• My pronouns are he/him.
• I'm from Vietnam, but my English is much better than my Vietnamese.
• My real name is almost impossible to pronounce, so I just go by Leo online.
• I'm a Computer Science student at the National University of Singapore.
• I was a gold medalist at IOI 2023.

That's about as much info as I'll give here. If you're curious, you can stalk me further. You have my permission. Just don't show up at my house unannounced.

Why this website?

When I was younger, I had a bad habit of permanently deleting everything I made online. I think I've reached the age where I can confidently share my thoughts and opinions, however silly they may be.

Also, before this website, I didn't have a proper place to write commentary on the things I made or the things I did. I think my writing will be useful, at least for me and my future self, if not anyone else.

However, this won't be a blog where I write about my daily experiences. I find that kind of journaling pretty exhausting to maintain.

Sometimes I will stumble across a stranger's blog, read a few posts, be mildly entertained, and move on. I hope someone out there has that experience with my blog.

My Interests

Here's a list of my interests, in (roughly) descending order of relevance.

• Competitive Programming

  I'm not nearly as competitive as I used to be, so these days, you're much more likely to find me as a problem setter than as a contestant.

• Project Euler

  On October 22, 2025, I completed all problems on Project Euler. If you're reading this, either I still have all of them solved, or I'm working on a problem right now.

• Drawing

  I recently started learning how to draw! You can browse my work on Instagram or right here on this site. I try to post when I'm not busy with other things :P

• Archive of Our Own

  Sometimes I might read (and write) on AO3, especially romantic slash fiction. What can I say? I like seeing people be happy.

• YouTube

  I have a channel that I sporadically upload videos to. I'm definitely not a "YouTuber" by any means. Check out this page for more details.

• Music

  I don't have a Spotify account or anything like that. I just listen on YouTube, mostly Vocaloid/SynthV/UTAU and rhythm game music.

• Rhythm Games

  Sometimes I play rhythm games at the nearest arcade. I used to be obsessed with Pump It Up, but now I just go whenever. I also play Taiko no Tatsujin and maimai.

Contact Me

Despite having a decent presence online, I'm a bit fussy about personal contact.

Assuming we don't already know each other, I'm on Discord at @sanguinechameleon.

Otherwise, please do not contact me anywhere else, including (but not limited to):

• Content platforms (e.g. YouTube, Instagram)

  You can comment on my stuff, but please don't reach out to me there.

• Problem-solving platforms (e.g. Codeforces)

  Please don't ask me for help. I can't offer much besides generic advice, sorry.

• Social media platforms (e.g. Twitter)

  I don't like social media at all. I only have accounts to view content.

• "Professional" platforms (e.g. LinkedIn)

  Eww. No. Gross. Never do this. Stop.

Feedback

Feel free to leave feedback on my work, constructive or otherwise.

Please note that I most likely won't respond, and occasionally I may remove comments. This is a personal decision that I hope you can respect.

I promise you that I read everything and I truly appreciate it! ❤️

Credits

This website was made possible with GitHub Pages and Jekyll. While both tools made things a lot easier, this was still my first experience with front-end development, and I'm satisfied with what I've made. You can view the source code for this website here.
