Currently Building

Work in Progress

Products, tools, and ventures I'm actively building.

Virtual Garage

Wessley AI

Understand your car in 3D. Plan repairs, upgrades, and order parts with model-specific precision.

Decentralized Pledges

The Peace Board

A live map showing where people stand on peace. Turning pledges into visible signal by country.

Product Studio

Two Circle Studios

Build products end-to-end in a week. Freelance design, high-impact client work, rapid prototyping.

Cosmic blueprint mapping engine

Omnis

Calculates and cross-maps your Dreamspell galactic signature, Tzolkin day sign, Human Design bodygraph, astrology natal chart, and Hebrew gematria into one unified profile — with relationship compatibility, daily forecasts, and an interactive graph of how it all connects.

Civic consensus for Israeli municipalities

Taruu

תַּרְאוּ — a civic consensus platform piloting in Kiryat Tivon. Citizens vote on local affairs with GPS-verified residency and SEL-DID identity, giving councils a transparent, community-backed picture of what residents actually want. The second iteration of ThePeaceBoard.

Cooperative memory for AI agents

Folklore

A decentralized cooperative memory and research layer for AI agents — every node learns locally, peers opt into trusted rooms, and knowledge compounds across the community with privacy preserved via DIDs. The evolution of Wellinformed.

Multi-agent deliberation engine

Forge

Eight battle-tested modes for copywriting, idea validation, feasibility analysis, planning, and bug-fixing. CLI-first, open source, no vendor lock-in. Routes across Claude, GPT, Gemini, Perplexity, OpenRouter and Ollama.

Global peace-pledge map

ThePeaceBoard

A live world map of where people stand on peace — citizens pledge and watch peace, conflict, and activity heatmaps update in real time, with an opt-in decentralized mode for anonymity. The original platform that Taruu grew out of.

Sassy responsive-layout auditor

Karen

Audits a URL across viewports with Playwright, detects overflow / spacing / typography drift, and emits an HTML/JSON report with suggested CSS/Tailwind diffs.

Open study toolkit for ethical hackers

Get CEH in 14 Days

Spaced-repetition flashcards, lab walkthroughs, and a self-adversarial Docker harness. The world needs more red-hat hackers — this is my contribution to that.

AR exhibition for civic frustration

The Tiny Civilian

An AR exhibition channeling the frustration with government and municipalities — and the power of the people. A companion art piece to ThePeaceBoard.

Studio Ghibli mod for Minecraft

GhibliCraft

A Spigot/Paper plugin that brings Totoro-forests, kodama, soot sprites and Catbus rails into Minecraft. Built on weekends as a love letter to play.

WhatsApp recap bot

Group Chat AI Newsletter

Summarizes a group's bullshit chat into a funny weekly newsletter. The first toy that made me laugh at my own code.
