About

“Ex-founder, 2M+ streams producer.”

Born in Shanghai, based in DC and SF. I'm a rising sophomore at Georgetown taking a gap year in the Bay — at Mercor, and building my own company. I've dabbled in finance along the way, and I make beats: verified on Spotify with 2M+ streams as Eternity X.

From: Shanghai, China
Based in: Washington DC & San Francisco
School: Georgetown University, Finance & CS
Currently: Mercor and Ambees

Ambees

Georgetown SLI Incubator

A two-sided recruiting marketplace connecting mid-tier Fortune 500 companies with university student talent — AI matching students to roles they're actually a good fit for, and giving recruiters a faster way to surface qualified candidates.

On one side: large, well-known employers that aren't Google or Goldman, and so struggle to compete for student attention on campus. On the other: students applying to dozens of postings with almost no signal about which ones fit. Ambees' core idea is AI cross-matching — instead of treating an application as a yes/no for one job, it reads a candidate's profile and routes them toward better-fit roles across an employer's openings, including ones they wouldn't have thought to apply to. Recruiters get AI-generated candidate summaries instead of stacks of resumes; students get a fast, swipe-style experience with voice-agent onboarding. A Delaware C-corp I founded and lead as CEO, with Yiran Hu as CTO — backed by Georgetown's Summer Launch Incubator and accepted into Microsoft for Startups.

Readahead

A Chrome extension that makes YouTube buffer far past its ~2-minute limit and hold one quality for the whole video. It patches the player's experiment flags before the player script loads and pins quality through the player's own API, with live buffer stats in the popup. Vanilla JS, zero dependencies.

A training sim for the ATSA, the FAA's air-traffic-control entrance exam. The scoring engine is built: a dependency-free C# library that scores gameplay telemetry into the six cognitive dimensions the exam tests — working memory, spatial reasoning, multitasking, decision speed, prioritization, mental math — tracking each against a personal baseline. The sim around it is in progress.

Music Production2024

2,000,000+

It started in seventh grade — I had opinions about every EDM track I heard and eventually decided to fix them myself. I picked up my mom's old MacBook, opened GarageBand, and never stopped. I always wanted to be a one-man band, able to play every instrument on a record, and I kind of got there. I switched to Ableton, started producing for rappers on BeatStars and SoundCloud, then built DX Media to connect artists I believed in with playlist curators who could get them heard. One of my own tracks landed on a Spotify editorial playlist — that was the unlock. Now I'm verified on Spotify with 2M+ streams as Eternity X. No label, no manager, just iteration.

Multi-Instrumentalist

The original dream was to play every instrument in a band by myself — and I kind of got there. I can play a lot of instruments, but drums is the one I play exceptionally. Hours behind a kit are how I decompress. Rhythm is the foundation of everything: music, trading rhythms, conversation pace. I just think in beats.

Channels

I vlog and post building-in-public content on YouTube and RedNote as itzdavezwrld.

Reading

Money Stuff by Matt Levine is the best thing written about finance — if you want to understand how markets actually work, read it every day. I also go through a lot of Y Combinator content, founders talking about the worst days of building. Recently I've been very into investing and startup books. Always open to recommendations.
