Cash Cow and TradeDesk

A research terminal where code decides which price moves matter and the model only explains them, plus a paper desk that refuses to claim an edge it cannot show.

Market research, paper onlyPaper only, no real moneyNo edge after fees

Results reported as they came: no paper book beat buy and hold after fees over 24 months

Problem
AI market commentary mixes invented reasons with real ones, and strategy dashboards show flattering numbers without fees.
My role
Solo builder: price feeds, rules, a backtester with a held-out period, paper strategy books and a native Mac dashboard.
Shipped
A CLI research terminal, a paper trading engine and a Mac dashboard.
Stack
  • Python
  • Public price data
  • Claude Code CLI
  • SwiftUI Mac app
  • launchd
Outcome
  • An eval fails the build if the dashboard claims an edge that does not survive the checks
  • There is no live trading mode

About me

Wilfredo Baez

Hi, I'm Wilfredo. I'm an AI product engineer in New York, building the products I want to use, and the systems that help me build them.

I work the way a lead works with a team. I decide what to build, write the spec, and direct AI coding agents through small changes I can review. Nothing is accepted on trust: every project here has a test gate, and anything that sends, publishes, pays or deletes waits for my approval.

Before this I spent years on the support side of tech at Apple and Geek Squad, provisioning devices at volume and fixing whatever people brought in. I still run Elevare Solutions, a small studio that builds websites and tools for local businesses. That is where I learned to listen to the people who use what I build.

I'm looking for a founding or early engineering role where I can own a product from its first useful version onward.
