Performance Engineering

Available for contract web work at $55/hr

Website Performance Engineering Diagnostics at $55/hr

Technical diagnostics for performance problems that need more than a plugin setting: Core Web Vitals, Lighthouse findings, render-blocking scripts, bundle weight, hydration behavior, caching headers, layout shift, and front-end optimization tradeoffs.

Performance Engineering problem fit

Performance Engineering problems this helps solve

  • Lighthouse or PageSpeed points to scripts, images, layout shift, or render delay
  • A Svelte, React, Shopify, or WordPress page feels heavy after real browser inspection
  • Bundle weight, hydration, third-party tags, or duplicated assets need review
  • Caching helps some pages but creates stale or inconsistent behavior
  • The team needs proof of what is actually slowing the page before changing production

Performance Engineering tasks

Performance Engineering implementation tasks

  • Run Lighthouse and browser diagnostics against key pages
  • Trace render-blocking scripts, third-party tags, and network weight
  • Review bundle output, hydration behavior, and front-end asset loading
  • Investigate Cumulative Layout Shift and unstable page elements
  • Check cache headers, Cloudflare behavior, compression, and hosting constraints
  • Document the practical fixes, tradeoffs, and limits

Performance proof

Proof of Core Web Vitals, Lighthouse, and page-speed cleanup

Performance engineering here is practical: find what is heavy, unstable, or blocking the page and clean up what can reasonably move.

  • Lighthouse Built this site as a lightweight proof asset with 100 Lighthouse scores in incognito.
  • Slow-site cleanup Moved slow, bloated sites from weak Lighthouse scores into the 90+ range where the platform allowed practical improvements.
  • Root causes Reviewed themes, plugins, scripts, images, cache, hosting, third-party tools, layout shift, and front-end code.

Performance Engineering in service work

Where Performance Engineering fits into website support

Performance engineering is the deeper diagnostic capability behind site speed cleanup, WordPress support, ecommerce support, platform reliability, and Core Web Vitals work.

Site Speed and Performance Cleanup

Client-facing speed cleanup for slow WordPress, Shopify, Svelte, React, and static pages where heavy scripts, oversized images, layout shift, caching confusion, or front-end weight are hurting user experience, Core Web Vitals, and conversion paths.

FAQ

Performance Engineering questions

Can you guarantee perfect speed scores?

No. Performance depends on hosting, themes, plugins, scripts, and business requirements. The work focuses on practical improvement.

Can you work from Lighthouse notes?

Yes. Lighthouse and PageSpeed reports are useful diagnostics when paired with browser inspection, network traces, and page-specific context.

Can third-party scripts be fixed?

Some can be deferred, cleaned up, or moved. Some are business requirements and need tradeoffs explained.

Does performance work help SEO?

It can support SEO and conversions, especially when slow pages, layout shift, poor mobile UX, or Core Web Vitals issues are part of the problem.
