MBA candidate at Berkeley Haas. Software engineer for the past four years at Goldman Sachs.

This site is a little more of me than the resume can fit. If you’re here, you probably already have the resume, so this is the rest.

About

A bit about me

I’m an MBA candidate at UC Berkeley Haas. Before this, I spent four years at Goldman Sachs as a software engineer, building deal execution platforms used by investment bankers globally. I’m now exploring product roles where I get to keep building, but with more leverage over what gets built.

I’m happiest at the intersection of technical and product work: close enough to the code to know what’s actually possible, close enough to users to know what’s actually worth building. Most of what I do outside school is some flavor of this.

What I’m into

01

Tactical Combat Game Simulator

A subscription-based combat simulator I built and run as a solo founder. It started as a side project to explore what one person could ship with agentic AI dev tools, and turned into a real product with paying subscribers. Most of what I've learned about product-market fit, pricing, and customer support, I learned from this.

02

Homebrew Media Server

I run my own media server for friends and family: fully self-hosted on personal hardware, publicly accessible with OAuth authentication and a hardened network setup. Started as a curiosity project, became a way to actually learn what running production infrastructure feels like when you can't outsource any of it.

03

Voice AI for Meaning, Not Just Words

A project I'm currently scoping: a voice AI that pays attention to prosody, resonance, and loudness. Not just the words being said, but how they're being said. The motivating use case is voice training for trans people, where existing tools mostly grade pitch in isolation and miss the rest of what makes a voice read a certain way. Most of what humans actually communicate sits in those non-lexical signals; most AI ignores them entirely. Curious what changes when it doesn't.

Outside of work

Cosplay & 3D-Printed Swords

I make cosplays for Comic-Con, and a chunk of that is 3D-printing weapons from scratch. The engineering side of cosplay (joints, balance, paint chemistry, how a prop holds up after eight hours at a convention) is criminally underrated.

AI Through Person of Interest

I'm on my fifth or sixth rewatch of Person of Interest, mostly because the show takes superintelligence seriously in a way most fiction doesn't. I've talked my way into 'research' framing whenever someone asks why.

Tinkering with My Setup

I spend a lot of time on my home setup: wiring up electronics, building out lighting, automating things around the house that probably didn't need automating. I also run open-source LLMs on my own hardware when something catches my interest. It's a useful counterweight to the rest of my life, where I mostly work in software.

Fantasy Fiction

I've reread Lord of the Rings somewhere past fifteen times. I'm trying to stop counting. Most of my reading is long fantasy series, the kind where the worldbuilding is half the point.
