Performance & Accessibility

Auditing and enhancing web applications for lightning-fast load times, superior Core Web Vitals, clean semantic SEO, and full WCAG accessibility compliance.

Overview & Purpose

Why fast-moving companies prioritize this service

A delay of just one second in page load can slash customer conversion by up to 20%. Similarly, neglecting keyboard navigation and screen-reader accessibility locks out millions of potential users and exposes businesses to compliance liabilities. I optimize existing and new web applications to be blazingly fast, lightweight, search-engine friendly, and accessible to everyone.

Measurable Business Outcomes

Significantly improved Google Core Web Vitals (LCP, INP, CLS)

Higher search engine ranking through clean semantic HTML and metadata

Lower bounce rates, particularly on low-bandwidth mobile connections

Full compliance with international accessibility standards (WCAG 2.1)

Problems I Solve

Turning technical friction into reliable business advantage

I frequently partner with founders and engineering leaders encountering these exact hurdles. Here is how I solve them.

Common Frustration

“Slow page loads causing high bounce rates and lost sales”

My Solution

Aggressive asset optimization, responsive image sizing, font subsetting, and route-based code splitting.

Common Frustration

“Poor Google Core Web Vitals scores hurting organic SEO ranking”

My Solution

Systematic remediation of Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).

Common Frustration

“Users on mobile devices experiencing battery drain and UI jank”

My Solution

Removing heavy third-party scripts, eliminating re-render loops, and utilizing hardware-accelerated animations.

Common Frustration

“Website inaccessible via keyboard, screen readers, or high-contrast modes”

My Solution

Implementation of semantic HTML5, focus-visible indicators, ARIA attributes, and accessible color contrast ratios.

Development Process

A disciplined, transparent delivery framework

From the initial discovery call to post-deployment verification, every stage is structured to eliminate guesswork and deliver on time.

01Stage 1

Baseline Audit & Profiling

Benchmark existing load times, bundle sizes, Core Web Vitals, and run automated & manual accessibility scans.

Key Milestones:
  • •Baseline performance report
  • •Accessibility violation breakdown
  • •Optimization roadmap
02Stage 2

Critical Path & Asset Optimization

Preload priority assets, compress imagery, configure responsive formats, and eliminate render-blocking CSS/JS.

Key Milestones:
  • •Optimized media assets
  • •Critical CSS inlining
  • •Preload & font display strategy
03Stage 3

Bundle & Runtime Refactoring

Apply dynamic code-splitting, replace bloated libraries with lightweight alternatives, and optimize React render trees.

Key Milestones:
  • •Reduced JavaScript bundle payload
  • •Memoized component trees
  • •Tree-shaken dependencies
04Stage 4

Accessibility Remediation & Verification

Add ARIA attributes, audit keyboard tabs, add skip-to-content links, verify color contrast, and re-benchmark.

Key Milestones:
  • •WCAG 2.1 AA compliant elements
  • •Accessible focus indicators
  • •Before & After comparison report

Frequently Asked Questions

Answers to common client inquiries

Transparent answers regarding scope, integration, ownership, and workflow.

Yes, absolutely. Most performance and accessibility issues can be resolved in place by optimizing assets, deferring non-critical scripts, implementing code splitting, refactoring wasteful re-renders, and introducing semantic ARIA roles into existing components.
