Why slow websites fail
Worse Rankings
Google penalizes slow pages. Core Web Vitals are an official ranking factor since 2021.
Users bounce
53% of mobile users leave a page if it takes longer than 3 seconds to load.
Fewer Conversions
Every second of delay costs 7% conversion. At CHF 100,000 revenue that is CHF 7,000.
Mobile Disaster
On smartphones performance is even more critical. Slow connections amplify the problem.
Systematic Performance Optimization
From analysis to implementation – I make your website measurably faster.

Performance Specialist with Developer Expertise
I understand not only the metrics but also the code behind them. This enables optimizations that really work – not just cosmetic improvements.
My approach: measure, prioritize, optimize, verify. With real data, not guesswork.
- Core Web Vitals (LCP, FID, CLS)
- JavaScript & CSS Optimization
- Asset Optimization & CDN
Optimize LCP, FID, CLS
The three Core Web Vitals determine your Google ranking. I analyze each one individually and optimize specifically.
- LCP < 2.5s – Largest Contentful Paint
- FID < 100ms – First Input Delay
- CLS < 0.1 – Cumulative Layout Shift
- INP optimized – Interaction to Next Paint

Slim down JavaScript & CSS
Bloated bundles are the most common performance killer. I identify unnecessary code and optimize the loading sequence.
- Code Splitting – Only load what is needed
- Tree Shaking – Remove unused code
- Critical CSS – Above-the-fold immediately
- Async/Defer – Avoid render-blocking

Images, Fonts & more
Images often make up 50%+ of page size. With modern formats and clever loading I save megabytes.
- WebP/AVIF – Modern image formats
- Lazy Loading – Load images on demand
- Font Optimization – WOFF2, Subsetting, Preload
- CDN Integration – Fast globally

Developer expertise instead of tool dependency
Real Code Changes
I optimize at the code level – not just with plugins that themselves cost performance.
Measurable Results
Before/after comparison with PageSpeed Insights, WebPageTest and Real User Metrics.
Focus on Impact
I prioritize by impact. The biggest wins first, not everything at once.
No Risks
All changes are tested. Your page works better after optimization, not worse.
How I optimize your performance

Comprehensive performance analysis with Lighthouse, WebPageTest and Real User Monitoring.
