Programming Career Development

  • First meaningful programming exposure: linked lists in college (Ray Babcock's class)
  • Mind blown by recursive data structures - "no end, infinite items"
  • Similar experience with decorator pattern - realized infinite possibilities
  • Recursion breakthrough came with maze-solving problem, not factorial/Fibonacci
  • First jobs: government robot programming, Schedulicity, Web Filings
  • Built startup doing text message marketing (2010) - ahead of its time like father's telecom startup
