Cryptical Development · since the 1990s

Fifty years of systems. A decade of markets.

From Fortran on punchcards to Python on AWS, I've built, secured and kept systems running for banks and businesses. Today I apply that same discipline to trading equities — and to building the tools I trade with.

Open the screener What I do

01 / Expertise

Technology

Troubleshooting, coding, designing, testing, documenting and administering systems across dozens of organizations — including operations and systems programming at the Federal Reserve Bank of Chicago.

› Mainframes, COBOL, Fortran
› Database security & information assurance
› Shell, Perl and Python automation
› AWS: EC2, Lambda, S3, Route 53
› MySQL on Linux

Markets

Self-directed swing trading in equities for roughly a decade, with a focus on Nasdaq names. Short holding periods, a small number of positions, and a routine that starts before the opening bell.

› Sector rotation & momentum via heat maps
› Chart-level technical confirmation
› Concentrated book — five positions or fewer
› IPO behavior: the pop, the drift, lock-ups
› Equities only, no leverage games
