PROFILE
Adam Tirella
Adam contributed to the Esri/calcite-design-system by delivering theming, accessibility, and UI consistency improvements across a wide range of web components. Over 14 months, he implemented CSS custom properties and design tokens to enable granular theming for components like tables, buttons, dialogs, and carousels, while also migrating legacy APIs and refining component styling. Using TypeScript, SCSS, and JavaScript, Adam enhanced component flexibility, improved accessibility, and reduced maintenance overhead by aligning with design system guidelines. His work included end-to-end testing, documentation updates, and cross-browser fixes, resulting in a more robust, customizable, and maintainable front-end architecture for the design system.

Aug 1, 2025August 2025 — Esri/calcite-design-system: Delivered a comprehensive Color Swatch System Migration to align with the design system. Implemented calcite-swatch and calcite-swatch-group components, migrated the color picker to use the new Swatch API, deprecated the old color-picker-swatch API, and refined UI spacing to match system guidelines. Refactored color-picker internals to rely on Swatch Group and Swatch, and updated documentation to deprecate the legacy component. This work standardizes color swatches across components, reduces maintenance burden, and enables future theming and accessibility improvements.

Jul 1, 2025In July 2025, delivered a cohesive theming strategy for the Calcite Design System by introducing CSS custom properties (design tokens) across three core components—Carousel, Dialog, and Button—enabling granular and consistent theming. Implementations covered: Carousel theming tokens for pagination, controls, and autoplay progress; Dialog tokens for corner radius, text colors, borders, and header/footer backgrounds; and Button shadow tokens. In addition, deprecated legacy button shadow color and completed a demo cleanup to remove unused CSS properties, reducing CSS debt and potential visual regressions. These changes establish a scalable foundation for design-system theming and smoother future updates.

Nov 1, 20242024-11 monthly summary — Esri/calcite-design-system: Delivered foundational theming enhancements and UI consistency improvements across core components. Implemented comprehensive CSS custom properties (tokens) for Calcite Panel and Calcite Input to enable extensive theming and customization, deprecating older tokens. Updated related components (e.g., Dialog) to adopt the new token system, improving consistency, theming flexibility, and maintainability. Improved Input resize behavior by removing the custom resize handle for textarea-equipped inputs to align with native browser behavior, simplifying usage and aligning with the Text Area component. These changes reduce styling debt, accelerate design-system iteration, and provide a more scalable foundation for theming across the UI.
