About

I'm a software engineer and AI systems builder based in Los Angeles. I studied Computer Science at UCLA, where I did machine learning research across two labs: the Julian McAuley Lab at UC San Diego and the Doheny Image Analysis Laboratory, with papers accepted into conferences. You can see them on Google Scholar. I also worked at Google, Amazon, and TikTok, shipping production systems at scale.

I also co-run two businesses: WinTone, a B2B company helping Chinese brands expand into the U.S. retail market, and Keystone Consulting, a college admissions firm with a 100% client success rate. Both gave me a firsthand look at how much time small businesses waste on tasks that AI can handle, so I started building the systems that fix that.

I'm not a consultant who has only read about AI. I've deployed it in businesses I actually run. When I work with you, you get someone who understands both the technology and what it's like to be on the receiving end of it.

Services

I've worked directly with many small businesses and found the same patterns everywhere: time lost to meetings no one recaps, inboxes nobody owns, and reports built manually every week. I approach every engagement from two angles: what the customer experiences and what the internal team actually has to do, then apply what I've seen building systems at Google, Amazon, and TikTok to design something that fits. No off-the-shelf tools. No generic advice. I sit down with you, understand your workflow, and build the thing that actually fixes it.

Meeting Automation
Every meeting automatically transcribed, summarized, and filed, with action items extracted and sent to the right people. Your team stops taking notes and starts moving faster.
Example output
Meeting: Q2 Pipeline Review · Apr 14, 2026
Summary: Team aligned on pushing the Acme deal to June. Legal needs to review the revised contract by Friday.
Action items:
  · Jason — send revised contract to legal by Apr 18
  · Sara — follow up with Acme on new timeline
  · All — reconvene Apr 22 for status update
Live demo coming soon
Email Workflow
All your team's email pulled into one place, summarized by AI, tagged with urgency, and turned into a clean action list. You stop managing your inbox and start managing your business.
Example output
Inbox digest · Apr 14, 2026 · 9:00 AM
● HighVendor invoice overdue · Reply requested by EOD

AI in Practice
Centralized Email & AI Workflow
WinTone · wintone.co · B2B retail expansion · Los Angeles

With a distributed team across time zones, emails were getting lost and nothing had a clear owner. I built a centralized system that aggregates all employee inboxes into a single pipeline. Each thread is summarized by AI, tagged with priority, and turned into a shared action list. Bottlenecks that used to surface in weekly calls now surface the same day.

Also automated the weekly client reporting process: performance data pulled, formatted, and emailed to clients without anyone touching a spreadsheet.

Document & Meeting Automation

Advisors were spending hours a week writing session notes, chasing document submissions, and manually following up with families. I automated the intake and document workflow so application materials move through the pipeline without manual handoffs, and built a meeting summary system so every session ends with a structured recap automatically sent to the client.

The result: advisors spend more time coaching, and no follow-up falls through the cracks.

When I'm Not Working
Running
Chasing a sub-16 5K. Also working toward a half marathon PR. I like progress you can measure in seconds.
Pool
Working on running out more often. Thinking through shot selection and position planning before I get to the table, not after.
Table Tennis
~2000 USATT rated. There's something satisfying about a sport where reading your opponent matters as much as reflexes. I take it seriously.
Pickleball
Playing on an RPM Friction Pro V2, no DUPR rating yet, but competing for the first time this year. Ask me how it goes.
Bowling
Throwing a 14 lb Raw Hammer. PR is 194 and I'm chasing a 200 game. So close.
Board Games
Cambio, Hues & Cues, Texas Hold'em, Dou Di Zhu, and Chess (1600+ on chess.com). I like games where thinking three moves ahead actually pays off.
Cats
I catsit whenever I can. I travel too much to own one, but the dream is a male calico (yes, I know how rare they are).
