What I'm working on.
Guardfolio.ai
I'm building Guardfolio — an AI-powered portfolio risk platform for retail investors. The core problem: most individual investors have no idea how concentrated their real risk actually is. Owning 10 stocks doesn't mean you're diversified. Sector overlap, factor loading, correlation — these are institutional concepts that never made it to the tools retail investors actually use.
Right now I'm deep in product development, refining the risk methodology, and working to find early adopters who feel this problem viscerally. The goal is to give individual investors the kind of portfolio lens that hedge funds take for granted.
Finance, fintech & building.
Publishing essays on portfolio risk, stock market strategy, and what it actually takes to build financial software — from someone who's spent time on both sides of the trade. No noise. Just things worth thinking about.

Questions I keep returning to.
- What does a genuine AI moat look like in a SaaS product — and how long before it gets commoditized?
- Why institutional risk frameworks never crossed over to retail, and whether it's a distribution problem or a product problem.
- How LLMs can move from summarizing financial data to actually improving financial decisions — not just explaining them.
- The gap between what founders say about product-market fit and what it actually feels like to be in it.
