Performance Optimization

Overview

I analyse bottlenecks and optimise frontend and backend holistically.
Using real performance data I identify technical pain points and implement a roadmap that cuts load times and boosts stability.

Services

• Performance audit: Lighthouse, Core Web Vitals, WebPageTest, real user monitoring.
• Frontend optimisation: code splitting, lazy loading, image optimisation, critical CSS.
• Backend optimisation: caching strategies, queue handling, API performance.
• Database tuning: indexes, query optimisation, read replicas, monitoring.
• Server & infrastructure: Nginx/Apache config, CDN, edge delivery, scaling strategies.

Outcomes

• Higher conversion & rankings thanks to lower bounce rates.
• Noticeably improved user experience across desktop and mobile.
• Stable systems during traffic spikes or campaigns.
• Measurable ROI through continuous reporting and KPI tracking.

Process

1. Measurement & analysis: benchmark over time, segment by device, region and browser.
2. Prioritisation: effort/impact scoring aligned with product, marketing and engineering.
3. Implementation: iterative optimisation with automated tests and safe rollback strategies.
4. Monitoring: dashboards, alerts and regular health checks.

Tools & technologies

• Google Lighthouse, WebPageTest, SpeedCurve, Calibre
• Sentry, Datadog, New Relic for performance and error monitoring
• CDN configuration (Cloudflare, Fastly) and edge functions
• Infrastructure as code for reproducible server environments
