Performance Optimization

Improving speed, stability, and usability through focused performance audits and optimization.

Slow pages cost you visitors, search rankings and sales. I start by measuring what real users experience (Core Web Vitals, Lighthouse, network and runtime profiles), find the few bottlenecks that matter most, fix them, and measure again so you can see the difference. The work covers the whole stack: heavy bundles and images in the browser, chatty APIs, and the slow SQL queries behind them.

• Baseline audit: Lighthouse and Core Web Vitals (LCP, INP, CLS) on mobile and desktop, with a written report.
• Bundle optimisation: lazy-loaded routes, deferred components, removing unused libraries and size budgets in the build.
• Images & fonts: modern formats (AVIF/WebP), right-sized images, lazy loading and font loading that never blocks text.
• Caching strategy: long-lived caching for hashed files, sensible cache headers and local caching for remote data.
• Rendering & interaction: smoother scrolling and animations, fewer layout shifts and less unnecessary change detection.
• API performance: fewer and smaller requests, pagination, response caching and async .NET endpoints.
• Database tuning: SQL Server query and index tuning for slow screens and reports.
• Third-party scripts: analytics, embeds and widgets loaded only when needed, such as click-to-load videos.
• SEO benefits: faster pages and healthier Core Web Vitals that support your search rankings.
• Before & after report: follow-up measurements and a short list of next steps to keep the site fast.
