How I work

🚀

Ship over polish

M1 walking skeleton in 2 days beats a perfect plan never built.

🔁

Learn in public

Writing what I learn forces real understanding. Vuihoc.AI is my open notebook.

🤝

Cross-functional empathy

Spent enough time with engineers, designers, finance, and customers to know nobody owns the truth alone.

🌱

Free-tier first

Constraint = creativity. Building 12 AI projects on free cloud tiers forces simpler architecture.
