PROFILE
Marcin Sawicki
Over six months, contributed to the livechat/design-system repository by building and refining reusable UI components, modernizing core features, and enhancing design system stability. Delivered features such as a modular animation hook, a range date picker, and a SelectableCard component, while migrating styling from SCSS to Emotion for improved theming and maintainability. Addressed documentation reliability by localizing assets and standardized component APIs for external use. Focused on UI/UX consistency, onboarding polish, and performance optimizations, alongside dependency and CI workflow improvements. Worked primarily with TypeScript, React, and CSS-in-JS, demonstrating a methodical approach to component development, refactoring, and design system governance.

Feb 1, 2025February 2025 — LiveChat Design System (livechat/design-system) delivered a cohesive design language and improved user experience. Key feature: Migration of styling from SCSS to Emotion across Accordion, Badge, DetailsCard, ActionMenu, ActionCard, and PromoBannerV2 to standardize theming and prop behavior; documentation updated to reflect migration and new props. A new Accordion prop was introduced to enable enhanced behavior. A rollback was performed to revert Emotion-based styling for Accordion back to SCSS to preserve maintainability, executed as a focused fix. Additional UX polish and performance work: RangeDatePickerV2 predefined label display, OnboardingChecklist customContent support, UserGuide UI/layout tweaks, AppFrame light-mode improvements, minor alignment tweaks, and performance improvements in AnimatedTextContainer. The overall impact: more consistent design system, faster styling iterations, improved onboarding and user experience, and reduced long-term maintenance burden. Technologies/skills demonstrated: CSS-in-JS with Emotion, SCSS interoperability, prop-driven UI, design-system governance, documentation contributions, and targeted performance optimizations.
