The Diagnosis

The "App Bloat" Epidemic: Hidden Code Rot is Slowing You Down.

Years of installing and uninstalling apps have left your codebase riddled with "zombie code." Your theme is loading heavy JavaScript libraries for features you don't even use.

The Symptoms

Your Google PageSpeed score is red, your bounce rate on mobile is over 60%, and your Cumulative Layout Shift Fix list is growing.

The Reality

Standard caching plugins cannot fix bad architecture.

Deep Code Remediation

Sentinu Solutions is a specialized Shopify Speed Optimization Agency. We don't just compress images; we refactor your theme's architecture. We dive into the Liquid code and JavaScript bundles to surgical remove bloat while keeping your site's functionality intact.

We focus on the metrics that actually matter to Google and your wallet: Core Web Vitals Optimization. We turn your sluggish site into a High Performance Ecommerce Site that ranks higher and converts better.

Core Web Vitals Optimization

We guarantee perfect scores on LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift). Every metric is engineered, not just measured.

JavaScript Bundle Optimization

We analyze and optimize your JavaScript bundles, removing unused code, implementing code splitting, and reducing bundle sizes by up to 70%.

Image & Asset Optimization

Beyond compression, we implement responsive images, lazy loading, and modern formats (WebP, AVIF) to reduce load times without sacrificing quality.

Edge Caching & CDN Strategy

We configure advanced caching strategies using Cloudflare or Vercel Edge, ensuring content is served from the closest location to your users globally.

Database Query Optimization

We audit and optimize database queries, reducing API call times and implementing efficient data fetching patterns that scale.

Lighthouse 100 Guarantee

We don't stop until your Lighthouse performance score hits 100. Every optimization is tested, measured, and validated.

The Process: Audit, Remediate, Monitor

01

Deep Scan Audit

We scan your entire codebase using proprietary tools to identify zombie code, heavy assets, and third-party script impact.

Scanning assets...

! Found 12 unused JS files

! Found 3.2MB unoptimized images

02

Surgical Remediation

Our engineers manually refactor your theme. We remove bloat, optimize loading order, and compress assets without breaking functionality.

Frequently Asked Questions

Will removing apps break my site?
We don't just delete files randomly. We trace every script to its source. If an app is vital, we optimize how it loads. If it's unused "zombie code," we excise it safely.
How much can you improve my score?
While every site is different, we typically see mobile scores jump from the 20s/30s to the 70s/80s, and desktop scores often reach 90+, resolving critical Core Web Vitals Fixes.
Will optimization break my site?
No. We use a careful, measured approach with extensive testing. All changes are validated in staging before going live, and we maintain full backups throughout the process.
Do you work with Shopify themes or only headless?
Both. We optimize Liquid themes, Hydrogen storefronts, and Next.js e-commerce sites. The techniques differ, but the goal is the same: perfect performance.
