i'm a berkeley cs graduate (3.9 gpa, BS CS 2025) obsessed with building and shipping. i grew up building legos, minecraft redstone contraptions, and running minecraft servers — then moved to coding mini games and have been building ever since. from 2016 to 2019, 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) 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 full stack ai engineer at cloud cruise (YC W24). previously, i was a forward deployed software engineer at robolabs, where i built memoryaid — a low-latency RAG inference system serving 200+ dementia patients in real-time with caching & batched embedding lookups, deployed via containerized microservices with 3 PhD psychiatrist advisors. before that, i was 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) — real-time computer vision, automatic clip detection, and a RAG-powered AI coach. i also built zigsaw.dev (2k+ mrr), generating 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 harvest api (reverse engineer any API from your browser with open-source LLMs at 98.4% accuracy) to prediction market trading bot ($1,325 peak profit exploiting Kalshi & Polymarket pricing inefficiencies) to prs calculator (650k genetic variant polygenic risk scores) to legalgpt (predicting supreme court outcomes via graph neural networks + fine-tuned mistral-7b — 80% auroc). other recent builds include tinyclaw (high-performance AI assistant in Rust, 22+ LLM providers), schism (activation steering for LLMs without fine-tuning), and doubletake news (120+ weekly newsletter subscribers).

my goal is to build durable software companies with small teams by obsessing over distribution, ux, and fast iteration. i want to build tools that make developers and teams drastically more productive.

Open — tldr

berkeley cs graduate (3.9 gpa, BS CS 2025), chancellor's scholar. full stack ai engineer at cloud cruise (YC W24). previously robolabs (RAG for 200+ dementia patients), palo alto labs (AI video analysis w/ chris brickley). built harvest api (reverse eng APIs w/ open-source LLMs), prediction market bot ($1,325 peak profit), tinyclaw (AI assistant in Rust), prs calculator (650k variant genomics), legalgpt (80% auroc supreme court prediction). won yc dedalus hackathon (zigsaw, 2k+ mrr). interned at duolingo, adobe, p&g.

Open — how i started

i grew up building legos, minecraft redstone contraptions, and running minecraft servers. that turned into coding mini games, then ecommerce stores and sneaker bots (30k+ from 2016-2019), then contributing to the dolphin emulator (reverse-engineering nintendo). i've been building ever since.

Open — my goal

build durable software companies with small teams. obsess over distribution, ux, and fast iteration. ship tools that make developers and teams drastically more productive.

Open — motivations

i want to understand how things work and build things that matter. the gap between what exists and what's possible is what drives me.

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

running a profitable AI company with a small, elite team — building infrastructure and tools that fundamentally change how software gets built.
