Performance Sprint

Price · ex. VAT €590

Duration 5 working days

Booked via Stripe · written brief

Built for sites that already exist and already work but feel slow on the seventy-fifth-percentile device. The brief is fixed and the deliverable is fixed: we move LCP, INP, and CLS into the green for the median real user, instrument the deploy pipeline so they stay green, and write a short field-manual for the team. Common fixes include image pipeline rebuilds, font-loading discipline, render-blocking work, hydration cost reductions, and route-level code-splitting.

Deliverables

What ships.

Standard list for this chapter. Adjusted per brief when the engagement warrants it.

01 A documented baseline measurement before any changes.

02 Image-loading discipline — sizes, formats, lazy / eager strategy.

03 Font-loading audit and fix — preload, subset, swap behaviour.

04 Removal or deferral of render-blocking third-party scripts.

05 Route-level code splitting where the platform allows.

06 Lighthouse-CI or equivalent baked into the deploy pipeline.

07 A short written field-manual for your team to maintain the work.

Phases

How it runs.

Same shape every time. Skipping a phase is rare and always written down.

01 — Mon — Baseline

Set up the measurement harness. Document where we start, in writing.

02 — Tue — Asset pass

Image pipeline, font loading, render-blocking third parties.

03 — Wed — Code pass

Hydration, code splitting, deferred work.

04 — Thu — CI pass

Performance budgets in the deploy pipeline.

05 — Fri — Readout

Final measurement, written manual, live walkthrough.
