Yes. Building on the WCM Core Components is the Adobe-recommended starting point and our developers follow it precisely. They create site-specific proxy components that inherit from a Core Component via sling:resourceSuperType, set the componentGroup so authors find them, and override only the HTL, dialog, or policy they need rather than forking the source so Adobe can keep shipping Core Component updates without breaking your build. They configure the editable template policies to expose the right options, use the Style System to offer authored variants instead of duplicate components, and keep the proxy thin. They version-pin the Core Components dependency in the Maven build so upgrades are deliberate. This approach gives you maintainable, upgrade-safe components. The PM confirms your Core Components version so the proxies target the correct base.

Yes. Sling Models are the backbone of component logic in modern AEM and our developers write them to best practice. They annotate models with @Model adaptable from SlingHttpServletRequest or Resource as appropriate, inject properties and child resources with @ValueMapValue and @ChildResource, use @OSGiService for service dependencies, and apply @PostConstruct for initialisation logic. They favour the Sling Model exporter (the @Exporter annotation with Jackson) so the same model can serve both HTL rendering and the JSON model API for headless and SPA use. They keep models free of business rules that belong in OSGi services, write them to be unit-testable with the AEM Mocks (wcm.io / io.wcm) framework, and avoid heavy work in the rendering path. The PM confirms whether you need request or resource adaptation so the model fits the use case.

Yes. HTL (HTML Template Language) is the only sanctioned templating engine in AEM and our developers use it idiomatically. They keep markup declarative data-sly-use to bind a Sling Model, data-sly-list and data-sly-repeat for iteration, data-sly-test for conditionals, and data-sly-resource and data-sly-include for composition while pushing all real logic into the Sling Model or a Java Use-class, never into the template. They apply the correct HTL display context so output is auto-escaped against XSS (html, attribute, uri, scriptString contexts), use data-sly-template and data-sly-call for reusable markup blocks, and rely on the resource and component objects through the global bindings. The result is clean, secure, maintainable markup. The PM confirms your component scope so the templates stay focused.

A PM is assigned within 10 minutes of booking and scopes your requirement on the first call. For a clearly defined task a custom component, a Sling Model refactor, or an HTL fix a vetted AEM component developer typically starts the same day. We offer three engagement models: project-based (a fixed set of components 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 front-end, authoring, and DevOps teams so component dialogs, clientlib contracts, and deployment pipelines are never a blocker.

Yes. A well-built component library is what makes authoring scalable, and our developers design for that. They build a consistent set of components with Granite/Coral UI dialogs that are intuitive for authors sensible field grouping, validation, placeholders, and inline help and use the Style System and policies so one component covers many visual variants instead of proliferating near-duplicates. They implement container and layout components that work with the responsive grid, expose content fragment and experience fragment rendering where reuse spans pages, and document each component so the authoring team can self-serve. They keep the library version-controlled and tested so it stays consistent as it grows. The PM confirms your authoring needs so dialogs match how your editors actually work.
