PROBLEMS WE SOLVE

Why is your site still slow after all that optimization?

You've done the optimization work. But the pages are still slow. These problems probably look familiar.

01

Optimized everything, still slow

Images compressed. Bundles split. Lazy-loading everywhere. The rendering layer underneath, the foundation, hasn't been touched.

02

Caching that breaks Itself

Stale when it should be fresh. Fresh when it should be cached. Your CDN, ISR, and data layers work against each other.

03

Fast frontend, slow experience

Your frontend is clean. But APIs take five seconds to respond. Your rendering strategy exposes every one of them.

04

Pages that don't rank

Client-side rendering delays indexing. For sites with thousands of pages, Google prefers server-rendered content. Your pages exist. They just don't rank.

Another quarter. Another round of micro-optimizations. Same pages, same problems. The work isn't wrong. It just doesn't reach the root cause.

It doesn't have to be this way.

OUR SOLUTION

From endless tweaks to lasting change

From chasing symptoms to fixing root cause. From optimization cycles that repeat to architectural change that lasts. Guessing becomes knowing.

What's actually slowing you down

We diagnose with field data, define the right rendering strategy for each page type, and implement caching that works together. No guesswork. No wasted optimization cycles.

How we approach it

We start with field data, not lab scores. Map your rendering strategy page by page. Fix what's broken.

Real outcomes delivered

Foundation fixed

Surface optimizations finally work because the layer underneath is right. You stop repeating the same fixes every quarter.

Consistent speed, every region

Same fast experience whether users are in New York or Singapore. Regional performance gaps stop hurting rankings.

Backend shielded

Caching absorbs traffic spikes so your slow APIs don't become slow pages. Users never see your backend latency.

Pages that rank

Server-rendered content that crawlers see immediately. No more indexing delays from client-side rendering.

Confidence to release

Deploy during peak traffic without holding your breath. Your caching and rendering architecture holds.

Cache that works together

CDN, ISR, and data layers aligned. Your caching works the way you expect.

OUR APPROACH

How we fix the architectural foundation that makes every other optimization work

01. Rendering Audit

open tab

We map your current rendering approach page-by-page: PPR, SSR, SSG, ISR, CSR. We identify where it's costing you performance. Most enterprises have never audited this layer. The gaps compound over time.

02. Rendering Strategy

open tab

Right strategy for each page type. Static where possible, ISR for dynamic content that tolerates staleness, PPR for selectively fresh regions and SSR only where freshness can't wait. Enterprises often default to SSR everywhere. Server costs spike.

03. Cache Alignment

open tab

CDN, ISR, and data layer caches aligned to work together. One misconfigured cache header is often the difference between a 3-second page and a 300ms page.

04. Backend Shielding

open tab

Caching configured to absorb traffic spikes so your slow APIs don't become slow pages. 80% of your traffic should hit cache. When it doesn't, the 20% hitting your backend defines your conversion rate.

05. Field Data

open tab

We measure with real-user data, not Lighthouse. Lab scores look 30-50% better than what real users experience. That gap is where rankings and conversions decay.

06. Cache Invalidation

open tab

Tag-based and time-based invalidation so content stays fresh without sacrificing cache hit rates. Updates publish when they should. Cached content serves when it should.
