Performance + Platform Engineering
Core Web Vitals, edge rendering, caching, observability.
When your site loads in 4 seconds and bounces on mobile, this is the bucket. Bundle / image / font diet, edge rendering, ISR, caching strategy, and the observability to keep it that way.
What you get
4 pillarsCore Web Vitals
LCP / INP / CLS targeted in the green band, on the slowest device your customer is plausibly on.
Edge + streaming
Edge rendering, partial prerendering, streaming HTML — moved to where it makes sense, not everywhere.
Cache strategy
CDN, Redis, Vercel runtime cache, framework caches — designed as one strategy, not five accidents.
Observability
RUM + synthetic + server traces, with budgets and alerts. Performance is a number, not a vibe.

Frequently asked
4 questionsWhat is Core Web Vitals and why does it matter?
Google's page-experience metrics: LCP (loading), INP (interactivity), CLS (visual stability). They are direct ranking factors since 2024. Fast sites rank higher, convert better, and bounce less. The wins compound.
How do you improve LCP and INP scores?
LCP: prioritize the hero asset, preload critical fonts, push image work to a CDN, use streaming SSR or Partial Prerendering. INP: defer non-critical JS, split heavy event handlers, avoid long tasks, and use the Scheduler API to break work into yieldable chunks.
Edge functions or Node runtime?
Edge for latency-sensitive routes (auth gates, redirects, personalized headers). Node (Fluid Compute on Vercel) for heavy compute, large dependencies, or stateful workloads. Vercel's default Fluid Compute now eliminates most cold-start arguments.
How is cache invalidation managed?
Tag-based invalidation (Next.js cacheTag, Vercel Runtime Cache API) — purge by tag instead of by URL, so editorial changes only clear what they touched. Mutations call updateTag explicitly; nothing relies on TTL guessing.
