Frontend Performance Audit
A ranked remediation backlog for Core Web Vitals, critical-path assets, and render risk across your primary user journeys.
Who this is for
Product and engineering leads whose public or authenticated surfaces miss Core Web Vitals targets on mid-tier devices common in Taiwan’s mobile traffic mix. Design-system owners who need performance constraints written into component acceptance criteria.
Result
You leave with a prioritized backlog tied to real journeys (not a generic Lighthouse PDF), ownership suggestions per squad, and a follow-up checkpoint after the first remediation sprint.
Scope included
- Baseline measurement on agreed journeys using lab and field-oriented checks
- Critical-path and third-party script inventory
- Image, font, and hydration pattern review where relevant
- Written findings with severity and effort bands
- Two working sessions with your engineers and one readout for stakeholders
- One follow-up call within 30 days of delivery
Out of scope
Full application rewrites, backend capacity planning, paid media or SEO content work, and ongoing on-call support (available separately as a retainer).
Provider & process
Led by App Valley Core’s consulting practice in Taoyuan. Process: intake brief → instrumentation week → analysis & workshops → delivery document → checkpoint.
Preparation
Provide staging or production access to the journeys under review, a component inventory if one exists, and a named counterpart from engineering and design.
Constraints
We audit agreed templates only. Expanding mid-engagement requires a change note. Findings assume your stack remains on the versions shared at kickoff.
Pricing basis
Fixed project fee starting at NT$148,000 for up to five primary journeys. Larger surfaces are quote-based after the scoping call.
Next step
Request an audit brief and list the journeys that matter most to revenue or retention.
