PROBABILITY EXPERIMENT
AM I UNLUCKY?
Coin flips, dice rolls, custom probability — and one simple question: are you unlucky, or is randomness just being random?
Try it ↗STATISTICS × DATA × WEB × AI
I turn ideas into working products.
NATTAPON BUILDS · Projects by Nattapon Surasin
I shape the idea, direct the product, test every iteration, and ship the result — turning ideas and data into real-world products.
AI shouldn’t replace what you can do.
It should expand what you can create.
— Nattapon Surasin
HOW I BUILD
I define the problem, shape the product, direct the AI, test the result, break what needs breaking, refine it, and ship it.
OpenAI Codex, ChatGPT, and GPT‑6 Astra handle much of the implementation. I lead the ideas, requirements, product direction, UX decisions, testing, iteration, and deployment.
