Israeli-American builder, 17, based in Irvine, California. 10th grader at TVT Community Day School.

I build AI agents and the environments around them. Most recently fixa.dev, an autonomous AI software engineer that plans, writes, runs, debugs, and ships software inside a cloud development environment.

My bet is that the frontier isn't generation — models already write code. The hard part is execution: an agent that observes reality, uses tools, recovers from errors, and reliably ships.

Ask the agent

I build agents, so I built one to answer for me. It's live — ask it anything.

Selected work

fixa.dev

April 2026 · solo

An autonomous AI software engineer that runs inside a cloud development environment. Describe an app and the agent plans, writes code, runs it, reads the logs, debugs, and deploys — a real execution loop rather than one-shot generation. Built around context management, tool calling, a universal MCP connector, and autonomous documentation research so the agent owns the whole software lifecycle. Originally launched as gelt.dev in October 2025, a weaker agent with few tools that compiled client-side via WebContainers.

shazam-clone

August 2024

A from-scratch recreation of Shazam's audio-fingerprinting pipeline — not just the UI. Records a short sample, builds a spectrogram with an FFT, extracts frequency peaks into a robust hash, and matches it against a fingerprint database. Next.js 14 + TypeScript on the front end, a Python / Flask / NumPy backend on Google Cloud Functions.

getmailyr.com

2023

An AI email assistant that lives inside Gmail. A Chrome extension turns a few words into a polished draft with tone and length control, routing across GPT, Claude, and Gemini behind a single freemium product so users never touch an API key.
