PROFILE
Christian Maniewski
Worked on the jumper-exchange repository over six months, delivering features that improved user experience, data integrity, and maintainability. Built and enhanced notification systems, refactored token management with object-oriented TypeScript, and revamped the Jumper Pass experience with reusable React components. Implemented client-side pagination, localization using i18next, and analytics integration to support engagement and scalability. Addressed UI clutter and access control by aligning notification visibility with wallet permissions, and improved data relevance through default sorting and risk categorization. Applied rigorous testing with Vitest and unit tests, ensuring stability and reducing runtime errors while collaborating across frontend and backend layers using JavaScript and TypeScript.

Jul 1, 2026July 2026: Delivered key features that improve data accuracy, UX consistency, and scalability across rewards, passes, and perks. Implemented rewards data source alignment by migrating to the /rewards endpoint and updating the UI to use ActivityCard, enabling more reliable data retrieval and display. Enhanced user experience with PassButton by showing the current level (with translations) and validating UI through Storybook. Standardized perk data flow with a centralized getAllPerks utility, ensuring all unlocked perks (including claimed) are visible, and adopting dynamic fetching in place of a fixed page size. These changes reduce data silos, improve analytics readiness, and lower maintenance overhead.

May 1, 2026Monthly summary for 2026-05 focusing on the jumper-exchange repository. Primary work centered on aligning the notification UX with Wallet Access Control (WAC) rules, delivering a gated notification experience that reduces UI clutter and enforces access controls. Key value delivered: users see the notification bell only when they have notifications enabled, which improves relevance, reduces noise, and helps prevent permission-related confusion. No major bugs fixed this month.
