Taoyuan · Frontend consulting

Performance audits that leave a design system standing.

App Valley Core reviews how your frontends load, render, and share components — then hands back a governance plan your team can actually run.

What we deliver

Three engagements, one craft

We work with product and design-engineering teams who need measurable page-weight cuts and a shared component vocabulary — without rewriting the product from scratch.

Component Debt Review

A focused pass over the heaviest or most duplicated components — weight, variants, and where consolidation pays off.

Design System Governance

Cadence, contribution rules, and review rituals so shared components stay coherent as squads ship in parallel.

Flagship

Frontend Performance Audit

A structured review of Core Web Vitals, critical-path assets, and render-blocking patterns across your key templates. You receive a ranked remediation backlog, ownership notes, and a follow-up checkpoint after the first sprint of fixes.

Typical duration: two to three weeks for a mid-size product surface. Delivery: remote workshops with optional on-site sessions in the Taoyuan–Taipei corridor.
