Founder · Founder of Scanr.ai.
I started trading US equities in 2020 during the COVID boom. After many wins, many losses, and nearly blowing up multiple times, I decided to investigate rule-based algorithmic trading systems to curb my emotions without dumbing down my actual strategies.
I quickly discovered the rules to my system could be built in a modular fashion, taking me down the path of building scanr.ai, the publicized system that runs on top of the same engine I use day-to-day for my own algos.
I built my first trading system in 2021 and have been refining it ever since. I have 6 years of experience in software engineering and data science.
I'm very excited to share my system with other traders!
Background
- Trading US equities since 2020

We asked a fruit fly's brain to find chart patterns
Google and Janelia published the complete male fruit fly connectome this month. We pulled its smell circuit out and asked it to rank chart patterns. It beat the floor, lost to a shuffled copy of itself, and lost to every model we train. Here is why, and how we find patterns instead.
