About

A person behind the notes.

Long bio

I work across embedded software, project engineering, and hardware-software integration — most recently building bare-metal C/C++ firmware for RP2040-based devices at Prong Technologies, and before that managing the electromechanical manufacturing of products from prototype through production at Everson Tesla. My background is in applied physics and electrical/computer engineering from Rutgers, including undergraduate research in graphene material characterization.

This site collects project case studies, technical writing, book notes, and quotations. Some entries are hardware builds documented start to finish; others are shorter notes on whatever I’ve been curious about — number systems, music theory, circadian rhythm, or the occasional detour into digital logic built one breadboard at a time.

Current interests

  • Embedded firmware for resource-constrained, bare-metal systems.
  • Small hardware builds that pair a physical constraint with a software solution — solar power budgets, e-ink refresh rates, that kind of thing.
  • Where music theory, circadian biology, and plain procedural thinking overlap.
