Yes. Client Libraries (clientlibs) are where most AEM frontend performance is won or lost, and our developers handle them properly. They organise clientlib categories, manage dependencies and embeds so shared code is not duplicated, and use the allowProxy flag with the etc.clientlibs proxy so resources are served from a cacheable, dispatcher-friendly path rather than under /apps. They configure minification and the long-cache versioning (LC) so updated bundles bust the cache cleanly, split critical and deferred CSS/JS to improve render-blocking metrics, and integrate a modern build webpack or Vite via the AEM front-end Maven plugin (the ui.frontend module) so the team writes ES modules and SCSS instead of hand-maintained static files. The PM confirms your build setup so the developer fits your existing tooling.

Yes. Design-system integration is core frontend work in AEM. Our developers map your tokens colour, spacing, typography scales into SCSS variables and CSS custom properties shared across clientlibs, then implement components so the AEM-authored markup matches your Figma or Storybook source of truth. They use the ui.frontend module to keep the design system as a real npm dependency rather than copied CSS, wire up the Style System so authors pick approved variants in the dialog, and ensure responsive behaviour, theming, and dark-mode tokens flow through consistently. They also keep accessibility intact semantic markup, focus states, ARIA so the integrated components meet WCAG. The PM confirms whether your design system lives in Storybook, a Figma library, or an npm package so the integration targets the right source.

They extend Core Components the supported way so your styling survives version bumps. Rather than forking component logic, they use the proxy component pattern a site-specific component that inherits from the WCM Core Component via sling:resourceSuperType and override only the HTL and styling they need. On the front end they target the stable BEM-style CSS classes the Core Components emit, layer site styles in their own clientlibs, and use the Style System to expose variants instead of duplicating components. They avoid editing the Core Component source directly so Adobe can keep shipping updates. Where deeper change is needed they document the override and keep it minimal. This keeps the front end maintainable and upgrade-safe. The PM confirms your Core Components version so overrides target the right markup.

A PM is assigned within 10 minutes of booking and scopes your requirement on the first call. For a clearly defined task a clientlib refactor, a design-system integration, or a responsive component build a vetted AEM frontend developer typically starts the same day. We offer three engagement models: project-based (a fixed front-end deliverable with milestones), dedicated (a developer embedded with your team full-time for a sprint or longer), and on-call burst capacity (hours drawn down as issues arise). You can scale up or down between sprints and cancel after any engagement. The PM coordinates the developer with your back-end, design, and DevOps teams so component contracts, build pipelines, and dispatcher rules are never a blocker.

Yes. Front-end performance is a frequent engagement. Developers audit the page with Lighthouse and WebPageTest, then fix the real causes: split and defer non-critical clientlibs to cut render-blocking resources, inline critical CSS, lazy-load below-the-fold images using AEM dynamic media and responsive renditions, and serve next-gen formats. They reduce JavaScript by removing unused libraries, code-splitting in the ui.frontend build, and deferring third-party tags. They ensure the dispatcher and CDN cache the clientlibs with long TTLs and proper versioning so repeat visits are instant, and they address layout shift (CLS) by reserving image and embed dimensions. The result is measurable LCP, CLS, and INP improvements that help both users and SEO. The PM confirms your performance targets so the work is focused.
