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

- Falcore system could be DOSed with single request
- Materialization feature could create billions of objects
- One request could kill one AWS machine
- Vulnerability existed in production for years
Streaming Career Transition
- Started streaming June 2018 for Extra Life charity (Guy Sereno influence)

Programming Language Perspectives
- JavaScript recommended for beginners (versatility, visual feedback)
- Currently exploring: Zig, Jai (Jonathan Blow's language)
- Go as main backend language
- Rust appreciation for memory management, mutability controls
- Vim motions superior for text editing efficiency
- Dislikes: "work smarter not harder" mentality, premature optimization advice
AI and Programming Future
