Jesse — PIIRAMO
Project-based profile

I turn ideas about software, data and hardware into things you can try. My projects combine ideas, interface design and technical development, including AI-assisted development tools.

A browser analysis workspace for historical ECB exchange rates and CSV data. Return, risk and correlation analysis, portfolio optimisation and Monte Carlo simulations. No live market feed or investment advice.

A modular browser workspace for objects, work sessions and personal tools. A working browser prototype, not yet a bootable operating system.
