I come from crypto trading, not engineering. Half a year ago I couldn't code at all. On day one I spent hours fighting PowerShell and OAuth errors just to get the tools running. That was my level.

My problem as a trader was always the same: entering positions on emotion, with half a plan in my head. Notes in Notion, numbers in Excel, charts in TradingView. The plan never lived in one place, so it quietly rewrote itself every time the candle moved.

So I built the tool I actually wanted. One canvas where you build the trade before you take it: entry points, TP/SL, risk, live prices, a discipline checklist. It won't even let you open a trade without a stop loss.

I vibe-coded the whole thing with Claude Code, from zero to shipped in about six months. Somewhere in the middle I deleted 18,000 lines of my own legacy code. Deleting turned out to be much harder than building.
