Technology map: recorded tools grouped by responsibility.

My engineering perspective: what each approach helps solve, and what needs care.

Responsive React: fix the behavior behind the layout

I start with the screen size and interaction that expose a problem, then separate layout rules from component behavior. Checking nearby widths helps reveal the underlying constraint.

The trade-off: A fix for one screenshot can fail at another width. The layout needs to respond to its content.

Tailwind or Material UI: match the styling approach to the job

Tailwind offers control through shared styling utilities. Material UI supplies ready-made component behavior. I choose the approach around the design freedom and interaction depth the interface needs.

The trade-off: These are example options. Existing conventions and the cost of customization matter as much as implementation speed.

Example tools: Tailwind CSS · Material UI. These illustrate the reasoning; historical use on this project is not established.
