ENGINEER

I build across the stack: React, Next.js, and TypeScript on the frontend, with Java/Spring Boot and Python/FastAPI on the backend. Recent work spans a live UC Davis Picnic Day platform for one of the nation's largest student-run events with 70,000+ yearly attendees, a Deadlock analytics app used by 1,000+ users, and an ML classifier over 32,000+ Spotify tracks.

Builder_Readout

  • 01 I like projects that have a real user on the other side, even when the first version is scrappy.
  • 02 The fun part is making the interface feel simple while the search, sync, caching, and validation do the work.
  • 03 I care about leaving a project easier to run, easier to understand, and easier to trust than when I found it.

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.
