I work as an independent forward-deployed engineer. I sit inside your team, in your repo and your tools, and build the apps, production AI pipelines and GTM systems you need. I launched Agent Hub at HubSpot and have shipped 13 AI products.
What I build.
Three kinds of project. Each one is something I’ve already shipped for myself or for HubSpot.
AI production pipelines
Take the prototype that works on your laptop and make it reliable at scale.
- Evals and test sets before launch
- Model routing, caching and fine-tuning
- Monitoring and cost controls
Built: PhoneScreen AI’s agents, run from ChatGPT or Claude (3,000+ screens)
AI GTM engineering
Pipeline that builds itself: research, enrichment and outreach, wired into your CRM.
- Enrichment and lead scoring
- Routing and personalized outbound
- CRM automation and clean data
Built: LeadShogun, and HubSpot data enrichment
