Independent investment research — every piece starts as a question, becomes a notebook, and gets published with the code and data pipeline attached.
I'm Jacob Windle, a software engineer. I build algorithmic trading and market-data tooling in Julia, and this site is where the research that falls out of that work ends up.
The format is deliberate: each piece is a Pluto notebook exported whole, so you can read the analysis and audit every line that produced it. If a number can't be traced to code and data, it doesn't get published.
Every AST SpaceMobile launch since the 2021 listing — how far the stock ran in the 7–90 days before liftoff, and what it gave back the week after. Spoiler: the run-up is real, early, and historically you sold the launch.
