Selected work

AI Concierge · Messaging

An AI concierge that acts as an intelligent front door for incoming WhatsApp and text messages — reading, triaging, and drafting responses, with automated business-card intake and personal-assistant tasks.

Live on GCP WhatsApp LLM agent
Agentic App · Inventory

StockAI

An AI-powered inventory manager (web + Flutter Android) driven by a Claude tool-use loop over a Supabase/Postgres backend. Users manage stock in plain language; the AI executes actions through defined tools.

Infrastructure · Orchestration

Multi-agent workflows

Workflows that coordinate teams of AI subagents in parallel — splitting work, delegating, and reporting back — to tackle research and build tasks that don't fit in a single context.

Sub-agents Orchestration
Tooling · Reliability

FastLink

A resilient browser-automation layer with retry logic and a three-tier vision fallback (Gemini → OpenRouter → Claude) plus verify-readback — keeping automated flows alive through flaky pages and API failures.

02

Community tech

Software built for the Orthodox Jewish community — where the domain logic (halachic time calculation, calendar-aware prayer) is genuinely non-trivial engineering.

Flutter · Prayer

AndDaaven

A davening (prayer) app with logic that adapts the tefilla to Shabbos and Yom Tov automatically.

Android · KosherJava

Zmanim Alarm

An alarm-clock app that computes halachic times (zmanim) with KosherJava and turns them into daily scheduling.

Client work · Web

Shul Portal

A contracted synagogue web portal — member directory, minyan & zmanim listings, and online donation / sponsorship — built to design spec.

Nonprofit · Web

Donation System

A donation-management system for nonprofit use, reproduced and coded end-to-end.
