ENGINEER

I build software people rely on, from C#/.NET advising systems at UC Davis to React and TypeScript interfaces, event tools, and game analytics. I care about clear interfaces, dependable data, and testing the paths that matter.

PERSONAL_LOG
ENTRY_001.log
GAMING
TAG: FPS // MOBA // RPG

I like games that give me something to chase. Sometimes that is aim training in Valorant, Overwatch, Apex, or Deadlock. Sometimes it is a long RPG night with Destiny, Elder Scrolls, Fallout, Monster Hunter, or Titanfall. I also play gacha games, mostly because I enjoy collecting tiny goals.

ENTRY_002.log
MEDIA
TAG: ANIME // MOVIES

Anime and movies are my favorite way to reset my brain. I like stories with style, heart, and a little melodrama. If something sticks with me, I will probably try to recommend it with too much detail and too much excitement.

ENTRY_003.log
FOOD
TAG: COOKING // FOOD CRAWLS

I like cooking for people and finding places that feel worth the trip. Food crawls are one of my favorite ways to learn a city. If I am travelling somewhere new, I am probably researching where to eat before anything else.

ENTRY_004.log
MUSIC
TAG: RAP // J-POP // EDM // 2010s POP

My playlists jump from rap to J-pop to EDM to 2010s pop, and I like that they do not make perfect sense. I also just started learning electric guitar, so right now I am in the charming phase where every clean chord feels like a small victory.

ENTRY_005.log
LIFE
TAG: FOOD // SLEEP // TRAVEL

I recharge through small rituals: a good meal, a new place to walk around, a quiet night, or a trip that gives me a story to bring back. I am happiest when there is something cozy to do and something new to look forward to.
