I leverage AI tools like ChatGPT, Claude, and OpenCode to deliver results at a completely different level โ but the thinking is always mine.
Here's how I actually use AI:
- ๐ง I lead, AI assists โ I define the architecture, the logic, the decisions. AI accelerates execution, not replaces judgment.
- ๐ Critical review always โ I never blindly paste AI output. I read it, understand it, challenge it, and adapt it to the real context of the project.
- โก 200% productivity โ combining my technical knowledge with AI tools lets me ship faster, debug smarter, and explore more solutions in less time.
- ๐งช Learning amplifier โ I use AI to go deeper into topics, not to skip understanding them.
"A hammer doesn't build a house โ the person holding it does. AI is my hammer."
