What I'm building

Live on the App Store

MealScout

AI nutrition tracking for iOS. Log meals by photo, text, or barcode and get calorie and macro estimates in seconds, with an AI coach that answers from your actual logs. Free tier included, premium priced near compute cost instead of fitness-brand markup.

Self-hosted

OpenAudioStack

Self-hosted audio AI infrastructure: open audio models running on hardware I own and manage, instead of renting inference by the API call. Built for privacy, control, and predictable cost.

Open models · Local inference · No cloud dependency
In progress

Finance agent workflows

Agent-driven personal finance and stock research: portfolio tracking, spending trends, scenario analysis, valuation notes, and repeatable research briefs. Produced on a schedule by agents rather than by hand.

Local AI lab

Private compute across NVIDIA DGX Spark, Mac Studio, and Mac minis running local models and around-the-clock automation. The testbed behind everything above: agents, audio, and finance workflows on hardware I control.

Why MealScout is priced near compute cost

Category pricing versus cost-anchored pricing, why AI apps break the SaaS pricing habit, and the spreadsheet behind a $5.99 subscription.

Finance × AI

I'm a CFA charterholder based in Minneapolis. My background is in financial services, with experience across wealth management, energy, and FP&A, and a lot of time spent presenting analysis to executives.

I work hands-on with Python, SQL, BI tools, data lineage, and workflow automation. On the AI side, I build daily: shipped products like MealScout, agents doing research and analysis on a schedule, and open models running on my own hardware.

Outside of work: skiing, traveling, golf, and getting outside when I can.
