Bilingual Shopify Storefront - Outdoor Living Brand
PROJECT_01

Bilingual Shopify Storefront - Outdoor Living Brand

A custom Shopify storefront built from scratch for an Israeli outdoor-living brand: no template and no page builder, just a hand-written Online Store 2.0 Liquid theme, fully bilingual Hebrew/English with true RTL, and a 141-product catalogue migrated behind 209 SEO redirects. Every product ships in two art directions (a studio packshot and a Mediterranean lifestyle scene, 282 AI-generated images curated by hand), switchable site-wide from one header toggle that follows the visitor across cards, product pages, hero video and search. An AI shopping advisor answers sizing, material and composition questions against the live catalogue in both languages, streaming, behind durable rate limiting, a daily cost breaker and a WhatsApp fallback. Rounded out with an IS 5568 accessibility pass, structured data, predictive search and a performance budget. Built end to end, but the client put the launch on hold, so the storefront never opened to the public and nothing in it was ever orderable. What you see here is the finished build, not a shop.

Not a live shop. This build never launched, so nothing is for sale and no order was ever taken. Live demo password: terrazza

PROJECT_02

Jordan's World (3D Verse)

An explorable 3D town where every house is a project: walk it with WASD, drag to look, day/night cycle, fog and bloom, and an intro flythrough. Each storefront wears a project's screenshot — tap a house to open its preview. Built from scratch on three.js with a single WebGL scene, screenshot-faced geometry, lightweight 512px storefront textures, and a guided tour mode.

PROJECT_03

Jordan in Space (Scroll-Flight Portfolio)

A portfolio you don't read — you fly through it. Scroll and a rocket launches from Earth, threads past the planets, orbits a ring of my projects, and kamikazes into the sun. Real NASA + Solar System Scope textures, a procedural nebula and HUD, and a full scroll-driven camera rig at 60fps in the browser. Built from scratch on React Three Fiber + Next.js, adapted from an open-source concept into my own space.

Fashnable
PROJECT_04

Fashnable

AI virtual try-on for online stores: drop a flat garment photo and get a realistic video of an AI model wearing it. The app generates an on-model shot — with selectable model gender, age, body type, ethnicity and background, plus optional face and background references — then animates it, replacing costly photoshoots. Built as a full SaaS: invite-only auth, a credit ledger, asynchronous generation via Cloud Tasks, durable Firestore + Cloud Storage, and Lemon Squeezy billing with credit packs and subscriptions.

Skill Factory
PROJECT_18

Skill Factory

Open-source Claude Code tool that studies how you actually work and writes new skills for you. A read-only scanner streams your own Claude Code session transcripts and skill-usage log, isolates the multi-step tasks you still do by hand (the ones no skill has automated yet), and distills hundreds of megabytes of history into a compact digest. One Claude pass then clusters them, ranks the top 5 by how often they recur and how much manual effort they save, and drafts a complete, ready-to-install SKILL.md for each. Runs entirely on your own Claude subscription via Claude Code, reads your transcripts read-only, and never writes a skill without showing a diff and asking first. Ships with a local web UI — Generate, review 5 ranked cards, one-click install — plus a CLI and a double-clickable macOS launcher.

shippost

Local-first tool that turns your dev work into ready-to-post LinkedIn drafts. A multi-pass engine mines the git repos you allowlist and, every couple of days, brainstorms angles then drafts, humanizes, scores and ranks 5 distinct options across four content pillars. Runs entirely on your own Claude subscription via Claude Code — nothing is uploaded and nothing posts automatically. Ships with a local Next.js app that shows the ranked drafts as cards with a live LinkedIn-style preview, one-click copy, and a voice corpus that learns from the posts you actually publish.

Open-source collection of battle-tested Claude Code skills for shipping safely. Includes /review-deep — a multi-agent code review that fans out four specialized reviewer agents (dependency impact, race conditions, logic & security, tenant isolation) then adversarially verifies every contestable finding with skeptic agents before reporting; /review-plan — a pre-implementation plan review that challenges assumptions, audits failure paths and ends with a Go/Adjust/Rethink verdict; /loopable — an automation scout that mines git history, scripts and Claude usage for recurring chores, ranks them, then ships the top candidate end-to-end (plan, review-plan, implement, review-deep, commit, ticket); and /init-agents — a scaffolder that detects a repo's stack and installs a tailored agent team (subagents, pipeline commands, quality hooks). One-line idempotent installer included.

yad2-watcher

Self-hosted, open-source watcher for Israel's biggest classifieds site (yad2) that turns a saved car or apartment search into instant, AI-scored Telegram alerts. Your own machine fetches the search, an LLM scores every new listing 0–10 against a per-vertical rubric, and only the good deals reach you — each with a one-line reason. Ships cars + rentals adapters, a one-command launchd/cron scheduler, and a Claude Code skill that turns a plain-English brief into a real search. Python standard library only, no cloud.

chaosbox
PROJECT_22

chaosbox

Open-source "vote-merged" playground with no maintainer in the loop: anyone opens a pull request adding a page under /contributions, the crowd votes 👍/👎 on the PR, and once it clears the vote bar with green CI and an hour of age a bot auto-merges and redeploys — shipping the contribution live in about 30 seconds. Every contribution runs sandboxed in its own iframe, so it can't touch the rest of the site, your cookies, or anyone else's page. Static HTML with zero dependencies, driven entirely by GitHub Actions.
