My role in the project
- Built product modules on Next.js in a ~40-person team: Centrifugo AI assistant, drag-and-drop calendar with recurring events, Kanban board, and AI essay auto-grading
- Initiated a shared UI Kit, code structure rules, icon centralization, and a Jest quality gate — reduced frontend regressions
- Shipped adaptive pixel-perfect UIs from mockups; used Zustand, TanStack Query, caching, and optimistic updates
- Replaced hardcoded roles with Unleash feature flags — access and limits change via UI without a release
- Set up OpenAPI code generation with Kubb, reducing manual API contract maintenance
