A few achievements

Berkeley CS (3.9 GPA), Chancellor's Scholar (2022), YC Dedalus Hackathon 1st, CalHacks 2nd.
Built profitable products (Zigsaw 2k+ MRR), Dolphin emulator contributor.

Current work & projects

RoboLabs — RAG memory aid app for dementia patients, 200+ users.
Zigsaw — LoRA fine-tuned video ad generation.
Projects: LuisOS, Timbre Space EQ, DoubleTake News.

Experience

DegreeSight — browser agents for college credit transferability.
Adobe — Creative Cloud API middleware.
Duolingo — AI-driven Stories recommendations, presented to CEO.

i'm a berkeley cs student (3.9 gpa) obsessed with building and shipping. i started selling toys in elementary school, moved to coding mini games in middle school, and have been building ever since. at 16, i made 30k+ running ecommerce stores and sneaker bots. at 19, i contributed to the dolphin emulator — the premier wii/gamecube emulator used by millions — which meant reverse-engineering nintendo, a company worth 100b+.

i've won yc's dedalus hackathon (judged by jared friedman, bill chen from openai, and guillermo rauch), placed 2nd at calhacks with talk‑to‑me (real-time voice translation with voice cloning), and won 7+ hackathons total. i received the uc berkeley chancellor's scholarship in 2022 and interned at duolingo (presented ai-driven story recommendations to ceo), adobe (api middleware for creative cloud), and procter & gamble (supply chain data engineering).

right now i'm a software engineer at robolabs — building a RAG memory aid app for dementia patients, live on ios/android with 200+ users at memoryaid.ai. i'm also running zigsaw.dev (2k+ mrr), generating realistic studio-grade video ads with a LoRA fine-tuned pipeline. on the side, i built luisos — a functional operating system with kernel threads, user program execution, and file system in c & assembly.

most of my work sits where ai, ux, and distribution collide: turning small, weird prototypes into products people use daily — from degreesight (browser agents for college credit transferability) to roam-fm (45k+ radio stations) and timbre space eq (3d audio editor). i'm also a cs61a/cs61b academic intern, calhacks mentor, and pianist in the cal nu jazz ensemble.

my goal is to build durable software companies with small teams by obsessing over distribution, ux, and fast iteration. in 5+ years, i see myself running a profitable ai company with a small, elite team — building tools that make developers 10x more productive.

Open — how i started

i started selling toys in elementary school, moved to coding mini games, and have been building ever since. i love turning simple ideas into working products.

Open — my goal

build durable software companies with small teams by obsessing over distribution, ux, and fast iteration.

Open — motivations

learning fast, shipping, and helping people use software to do more with less.

i'm hard on myself because i'm always chasing the next target. if i ever stop growing, it means my best days are behind me. the process is rough but i thrive in it.
