About Me

Sat, 24 May 2025 00:00:00 +0000

I am an aspiring fullstack developer in Hong Kong. I graduated from HKUST (BSc in Mathematics and Economics, minoring in IT) in 2020 👨‍🎓. Information Technology was not an industry I would see myself in, but after landing a job in a FinTech company I have fully embraced it. I enjoy the rapidly changing nature of this industry, being on the cutting edge of technology is awesome.

While I am not at work, I enjoy tinkering with my homelab. Having alternatives to popular services hosted in my own house gives me senses of privacy and accomplishment, and I learned a lot in the process of setting these up. I also like playing video games, particularly the most challenging ARPGs (e.g. Dark Souls series, Monster Hunter series). Hit me up if you need a buddy in Monster Hunter games!

作為一個IT從業員🧑‍💻，工作上必然會多多少少接觸到Linux。

我一直都有興趣轉用Linux，遊戲是我留在Windows的唯一原因：Linux對遊戲的支援遠遠不及Windows。

Starting on Homelab

Wed, 05 Apr 2023 00:00:00 +0000

My journey of homelabbing started on July 2021.

I just finished writing my Discord bot prototype and was looking for a place to host it. I first looked for free cloud services. As my knowledge of cloud was really limited at that time, I gave up and went for real hardware instead. (I would use Oracle Cloud now if I were to choose one, they provide an always-free tier)

I was about to buy a Raspberry Pi 4B, the price was (and still is) outrageous, but I couldn’t find of a better alternative. Then the sysadmin in my company heard about this and gave me a mini PC for free (Thanks, Andrew🙆‍♂️).
