Step 2 — Design

I plan clean, simple systems and structure the solution before writing code.

Step 3 — Build

I develop fast, functional, and reliable features using modern web technologies.

Step 4 — Refine

I optimize performance, fix edge cases, and improve the small details that make everything feel right.
