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 multilingual voice translation with voice cloning, 100+ concurrent users, zoom integration), and won 4+ 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 forward deployed software engineer at robolabs — i built memoryaid, a low-latency RAG inference system serving 200+ dementia patients in real-time. i optimized the retrieval pipeline with caching & batched embedding lookups, deployed via containerized microservices with 3 PhD psychiatrist advisors. the app helps patients and caregivers by surfacing personalized memory cues, medication reminders, and contextual life history — reducing cognitive load and improving quality of life.

i'm also a founding engineer at palo alto labs, where i architected an AI basketball video analysis platform partnered with chris brickley (trainer of lebron james, kevin durant). the system uses real-time computer vision for automatic clip detection, jersey OCR for player identification, and a RAG-powered AI coach that lets you query footage in natural language. i'm also running zigsaw.dev (2k+ mrr), generating realistic studio-grade video ads with a LoRA fine-tuned pipeline.

most of my work sits where ai, ux, and distribution collide: turning small, weird prototypes into products people use daily — from prs calculator (full-stack genomics platform processing 650k genetic variants for polygenic disease risk with ancestry-aware UK Biobank normalization) to legalgpt (predicting supreme court outcomes via citation graph neural networks + fine-tuned mistral-7b — 80% auroc). other recent builds include doubletake news (left/right news comparison with AI bias detection, 120+ weekly newsletter subscribers), retroplay (web emulator for retro consoles with cloud saves), degreesight (browser agents for college credit transferability), 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.

Open — where i see myself in 5+ years
