Some things I believe:
- Your AI problems aren't AI problems - they're usually data, process, or people problems
- Sell outcomes, not tasks
- Simplicity beats complexity - if you can't explain it simply, you don't understand it
- Measure what matters - does this solve a real problem someone will pay for?
- Experimentation speed is your only moat
- Confidence is the memory of success - practice more than you play
What I do:
- AI implementation consulting - help companies turn prototypes into production systems
Open source:
- Instructor (3M+ monthly downloads, 8,000+ stars) - Structured outputs from LLMs, recognized by OpenAI
