One year at trading firm; scripts are saturating CPUs, servers are choking.
Forced to restart them daily.

2025-02: Built Bumblebee: a C# WinForms desktop app that records browser
sessions and synthesize browser automation scripts. Andy helped.

JS hooks, WebView2 browser, Scintilla.NET editor emit events. Backend
interprets them and emits Selenium code.

Two linear lists store events and code—no time for ASTs. Mid-session manual
edits desync lists, block optimizer. Workaround: only edit script after
recording.

2025-03: Shipped first iteration. Began work on key optimization: bypass the
browser, grab data files directly.

2025-04: Abandoned project. Left the firm.
