PROFILE
Mattia Simonato
Worked on the percona/pmm repository over three months, delivering four features focused on frontend reliability and user experience. Built a centralized API error interceptor with snackbar notifications to standardize error handling and reduce notification noise, using React and TypeScript. Streamlined dashboard offerings by removing experimental dashboards, simplifying navigation and reducing maintenance overhead. Enhanced Real-Time Analytics navigation by ensuring filter and sort synchronization, migrating logic to standardized hooks, and adding targeted tests for session management. Improved session integrity and navigation stability, addressing sidebar duplication and login/logout state handling. Leveraged skills in API integration, dashboard development, and testing with JavaScript and TypeScript.

Jun 1, 2026June 2026: Key PMM improvements focused on Real-Time Analytics navigation and session management. RTA navigation now respects filters in the details pane and stays in sync with table sort, with added tests; overview navigation migrated to standardized hooks for better consistency and maintainability. PMM navigation was hardened to avoid duplicate sidebars, manage login/logout states, and stabilize Grafana iframe loading, strengthening session integrity and reducing UX glitches. Tech areas: React, percona-ui navigable hooks, TypeScript, and cross-module auth/session handling.
