A selection of AI projects. Each one is framed the same way: the problem, the solution, and the stack that made it work.

Customer Support X-ray

A free tool that reads a store's public support pages and mirrors back how an AI agent would handle their top tickets - grounded replies, honest cost and coverage estimates, and a shareable result card. Built so every use is its own distribution.

Share Wings - Multi-Brand Aircraft Dealership Platform

Four products - a multilingual marketing site, an agentic AI sales concierge, a HubSpot-replacement CRM, and a post-sale customer portal - for a Swiss aircraft dealership, shipped as one Next.js app on one Postgres.

Autonomous Job-Hunt Engine

An end-to-end agentic system that runs an entire job-search funnel - discovering, scoring, tailoring, submitting, handling recruiter replies, and even placing screening phone calls - instrumented so every action is logged, gated, and reconcilable to the cent.

Customer Support X-ray v2 - From Broadcast to Sniper

Turns a viral AI teardown tool into a targeted lead machine: cheap tech-fingerprint qualification feeds a Claude-powered pipeline that finds, scores, and ranks the exact e-commerce stores most likely to buy - all surfaced in a team dashboard backed by live conversation listening.

AI-Native Instagram Publishing Pipeline

A production-grade system that turns uploaded photos into a curated, auto-scheduled, auto-published Instagram feed - three Claude agents for the judgment calls, deterministic code for everything that must be exact.

Content Automation v2 - Deleting 2,400 Lines and a Class of Bugs

Deleted a Redis-backed Railway worker and BullMQ entirely by turning Postgres into the job queue, cutting ~2,400 lines, ~85% of scheduled invocations, and a whole class of silent distributed-systems bugs.

Customer Support X-ray - The Outreach Strategy

A closed-loop outbound system that sources e-commerce stores, qualifies them cheaply, runs an AI teardown of their support tickets, and emails each owner a personalized card linking to their own result - with every move logged to a team dashboard.
