Hi, I'm Nathan.
Product Leader. I build AI-driven products, platforms, and internal tools. Ten years shipping across healthtech, SaaS, and marketplaces. Ask about real work, side projects, or how I think.
The portfolio for problem solvers.
Break down problems together.
The chat builds on your question, expands on what matters, and simplifies complexity one step at a time — grounded in 10+ years of what I actually shipped.
Tackle your toughest hiring work.
Senior PM evaluation is hard. Ask specific, weird, adversarial questions and see how I think. No polished preset answers — the knowledge base is real notes, not a résumé.
Explore what's next.
Currently running Single Fin Consulting and shipping Virgin Islands Villas. Available for senior roles that need somebody who still writes code on the weekend.

New York · open to senior roles
I'm a product lead who still writes code on the weekend. 10+ years across healthtech, SaaS, ecommerce, and real estate — currently running Single Fin Consulting with three active engagements across DTC telehealth and luxury retail.
I like problems at the operator-product seam: domains where operational complexity and AI potential intersect. Workflow redesign, applied AI systems (lead intake agents, RAG pipelines, underwriting models, SMS sales agents), data infrastructure — consolidating fragmented operational data into something analytics and automation can actually use.
Technical depth in Python, TypeScript, React, and SQL. Designed and shipped production agent and RAG systems, and build solo end-to-end with Claude Code and Cursor. Based in New York. Open to senior IC or head-of-product roles. Happiest when I can sit next to engineering and talk to customers the same day.
