About me

Designer and product builder

I’m currently a Product Design Lead at Pigment where I work on AI agents for financial planning. My main value add comes from business experience, I approach design as a tool for revenue and leverage, and I tend to think in terms of systems.

Before Pigment, I founded two companies. I sold one early; the other I ran for two and a half years before shutting it down. After that, I joined a venture studio to learn how to structure innovation more deliberately. Later, I spent three years at Meta, where I learned what building at scale really means, and how systems, process, and organization shape outcomes.

My blog

I like to document what I learn and build. Topics range from AI agents to product strategy.

A baby on the way, moving to a different country, a new job, and buying a house, all in the last 12 months. That's why I wanted to start budgeting properly. So I looked at what was available. YNAB, Copilot, Monarch... all these are subscription-gated and cloud-dependent. None have a good free tier or great AI features.

5 Financial AI Benchmarks for anyone building financial AI agents: what they test vs. don't test

In late 2023, GPT-4 got 81% of questions about SEC filings wrong. That number comes from FinanceBench. Models have improved since then but the result set off a wave of new benchmarks. Each one trying to capture a different slice of what "financial AI" means. In this article, I map those benchmarks, breaking down what they test and identify where the gaps are.

7 UX patterns for better human oversight in ambient AI agents

Ambient AI agents (the agents that run in the background) are reshaping work. Yet product designers are missing a shared design language for building them. This article introduces seven UX patterns that let agents act autonomously while keeping humans in the loop and in control.
