How it works

01 / AUDIT

We inspect the existing frontend, performance data, accessibility signals, and implementation patterns to identify the issues that matter most.

02 / FINDINGS

We document what we found, why it matters, and which changes should happen first.

03 / REMEDIATION

We implement the agreed changes and validate them against the original findings.

04 / VALIDATION

We re-test the implementation and verify that the changes behave as intended across the relevant devices, browsers, and user flows.

Frequently Asked Questions

Do you guarantee a perfect Lighthouse score?

No. Lighthouse is useful for identifying potential problems, but it isn't the same as measuring how real users experience a site. We focus on the underlying issues and, where applicable, validate improvements against real-world Core Web Vitals.

Can you handle backend infrastructure?

Our Web Development service focuses on frontend implementation and architecture. Infrastructure, deployment, monitoring, and related operational work are covered through our DevOps service.

Can you work within our existing codebase?

Yes. We first assess the existing stack, architecture, and constraints before recommending changes. Where the foundation is sound, we improve it rather than rebuilding unnecessarily.

How do you measure and validate Core Web Vitals improvements?

We validate performance improvements against real-user metrics (Chrome User Experience Report / CrUX) and synthetic field data, focusing specifically on Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP).

What accessibility standard do your remediations target?

Our accessibility work aligns with WCAG 2.2 Level AA guidelines. We audit and remediate semantic HTML, keyboard focus management, ARIA roles, color contrast, and screen-reader compatibility (tested across VoiceOver and NVDA).

Will your code changes break our existing UI or visual design?

No. Our implementation work focuses on underlying structural markup, asset loading strategies, main-thread optimization, and accessible component patterns. We work strictly within your existing design tokens and CSS architecture without altering visual styling.

How does the handover and documentation process work?

Upon completion, we provide clear documentation detailing all code modifications, performance budget rules, accessibility findings, and recommended maintenance patterns so your team can maintain the standards long-term.
