Technical / AI Product Manager
Product manager.
I also build my own tools.
I lead product at Linkhouse day to day. When off-the-shelf tools don't fit, I put my own together with AI — some are in production, the rest I make after hours.

A semi-automated job-search assistant + CRM.
A daily automation pulls offers from multiple sources, scores how well they fit my profile, and drafts messages to recruiters. The whole funnel — from scoring to follow-up — on one board. A private tool I built for myself.

Product Manager at Linkhouse by day; after hours I build my own tools — usually because I need them myself. Sometimes something less serious: an AI song generator or a small Phaser game.
AI is my everyday workshop — prototypes, content, automating the boring parts. I like having something that works first, then making it simpler.
At Linkhouse I've built Ad Opus, among others, and internal Claude skills for docs and content. I started with simple scripts and SQL, and worked my way up to whole tools.
Looking for a product role where I can keep doing this.
