Experienced Full-Stack Developer for Polymarket Analytics Dashboard Upgrade

We are seeking an experienced full-stack developer to significantly improve and extend an existing self-hosted analytics dashboard designed for Polymarket traders. This crucial tool aggregates positions across various markets, providing insights into portfolio exposure and cross-market behavior. The primary goals for this project include resolving data inconsistencies between API and WebSocket states, enhancing performance for large portfolios (100+ markets), refining the user interface for clearer exposure and risk visualization, and integrating basic cross-market analytics such as exposure overlap and grouping.

Key work areas will involve establishing reliable data synchronization with robust REST and WebSocket reconciliation, effectively handling edge cases like ghost fills and delayed updates, optimizing frontend performance and rendering for a smooth user experience, and implementing the necessary logic for exposure and correlation analysis.

Important requirements for this role include proven experience with real-time systems (e.g., WebSockets, trading data, or similar applications), strong debugging capabilities to tackle inconsistent APIs and race conditions, and the ability to design highly reliable and stable systems. Deliverables for this project will include clean, well-documented code, a stable application that reliably handles all identified edge cases, and clear, simple setup instructions for future maintenance.
