About
I'm a full-stack developer with an IT infrastructure background, building web, mobile and desktop apps end to end with React, Node.js and React Native. I build tools for problems I actually have, and I use many of them daily.
I'm currently studying AI-Native Full-Stack & Architecture at 10x Academy and building my own projects while looking for a full-stack role. Before that I worked in IT support at Ramat Gan Municipality, which showed me every day what actually breaks for real users, and I carry that into how I build. I published one of my tools to the Chrome Web Store, and I graduated the John Bryce Full-Stack course with honors.
Open to full-stack, frontend, backend and React Native roles. I also bring hands-on IT support experience.
iOS · Android · Web744practice questions, plus 74 fallacies and 12 debates
Steelman
Pre-launch
Private repo
Problem: Everyone has the list of logical fallacies. Nobody trains the reflex to spot them.
What I built: An education app for iOS, Android and web that trains you to catch bad arguments. It has skill trees and offline-first sync. The Astro website opens with a playable "Fair, or a fallacy?" demo and a waitlist.
Proof: 74 fallacies, 744 practice questions, 12 debates and 20 LSAT-style drills ready in the app.
Desktop · Spotify465 msof the 567 ms median sync lag came from polling. Running inside Spotify removes it.
Sterrify
Daily use
Problem: Playing along meant switching between Spotify and Songsterr while holding an instrument.
What I built: An Electron app that syncs Songsterr to Spotify and switches instrument and tuning automatically. I then rebuilt it as Sterrify Tabs Private repo, a Spicetify app that renders the tab inside Spotify with alphaTab. The old app polled the Web API, which caused 465 ms of its 567 ms median sync lag. Running inside Spotify removes that delay. It also separates song stems on the GPU, and a C#/WebMIDI bridge switches my amp and tuning automatically.
Proof: I use it daily. Sterrify Tabs has an automated test suite.
Android · Android Auto10 releasesand 128 commits, v1.1 to v2.5 in about two months
AC Notification
Daily use
Problem: I kept walking into a hot apartment because the AC only came on once I was already home.
What I built: A geofence around home triggers a 1-tap "turn on AC" notification on Android and Android Auto. A Windows server (Python Flask, exposed through ngrok) auto-discovers the Midea ACs on the home network and controls them directly over the LAN.
Proof: 128 commits and 10 GitHub releases (v1.1 to v2.5) in about two months. I use it daily.
Chrome extension5.0 ★from 24 users on the Chrome Web Store
YouTube Watch Later Manager
Published
Daily use
Problem: Saving or removing a video from Watch Later is buried in YouTube's menus.
What I built: A Chrome extension with 1-click Watch Later buttons across YouTube. It matches icon shapes instead of English text, so it works in any language. It finds buttons at click time, because YouTube reuses page elements. Theme-aware, with no trackers.
Proof: 24 users and 5.0 stars on the Chrome Web Store. I use it daily.
WebReal-timedrag-and-drop task canvas, synced over Socket.io
Forest
Paused
Problem: My to-do lists got cluttered, and I lost the big picture of what mattered.
What I built: A canvas-based task manager with drag-and-drop and real-time sync over Socket.io. React 19 and Vite on the front end, Node.js, Express and Prisma on the back end, with Jest tests.
Status: Paused. A mobile companion with time- and location-based reminders is planned.
Mobile · Hebrew, right-to-left4 gamesand an in-app economy with 16 cosmetic packs
Grapevine
Built with a friend
No longer in use
Why: A creative and technical experiment. We built our own social network, I talked our friend group into using it, and then we added games and an in-app economy to reward playing.
What we built: A Hebrew, right-to-left mobile app with posts, comments, custom Golden Grape and Raisin reactions, and push notifications.
Games: Two replaced party games we used to play with pen and paper or had to work hard to invent on the spot: Land City, a 14-category multi-page form with shared state, and a rule game that builds a fresh rule each round from a recursive grammar. Eshkolosseum is a nightly D&D-style auto-battle between our characters, run by a scheduled Node.js server, where players bet coins on the fighters. Eli Clicker is an idle game that cashes out into coins.
Economy: Players earn coins by winning bets and playing, and spend them in a store of 16 cosmetic packs that restyle their posts.
Windows desktop0 keystrokessimulated since the rebuild on Windows UI Automation
Friendmeter
Daily use
Private repo
Problem: I wanted my friends always in view on my desktop, not hidden inside two separate apps.
What I built: A Windows desktop widget: a "Liquid Glass" Rainmeter skin plus a Node.js bridge. Clicking a notification jumps to the chat. An early version simulated keystrokes and could type a name into the wrong chat. I rebuilt it on Windows UI Automation, with no typing and reliable Hebrew name matching.
Proof: I use it daily. Covered by unit tests.

Android widget1.9 MBAPK, down from 13.9 MB with R8
Android Bluetooth Control Widget
Daily use
Private repo
Problem: Android makes you dig into system settings to connect one specific Bluetooth device.
What I built: A one-tap home-screen widget that works without root, using Shizuku. Android 12+ hides MAC addresses, so it matches devices by name instead. R8 shrank the APK from 13.9 MB to 1.9 MB.
Proof: I use it daily.
