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, poly-opt, designed for polymarket traders. This tool is crucial for aggregating positions across various markets and visualizing portfolio exposure and cross-market behavior.

The primary goals for this project include:
*  Resolving data inconsistencies between API and WebSocket states to ensure accuracy.
*  Enhancing performance to efficiently handle large portfolios, specifically those with 100 or more markets.
*  Improving the user interface to provide clearer visualization of exposure and risk.
*  Implementing basic cross-market analytics, such as exposure overlap and grouping functionalities.

Key work areas will involve:
*  Establishing reliable data synchronization mechanisms, including REST and WebSocket reconciliation.
*  Developing robust solutions to handle edge cases like ghost fills and delayed updates.
*  Optimizing frontend performance and rendering for a smoother user experience.
*  Implementing straightforward logic for exposure and correlation analysis.

Important requirements for this role include:
*  Proven experience with real-time systems, such as WebSockets, trading data platforms, or similar high-frequency data environments.
*  Strong debugging capabilities, particularly with complex issues like inconsistent APIs and race conditions.
*  A demonstrated ability to design and implement reliable, robust systems, not just user interfaces.

This project is expected to take approximately 2-3 weeks, though the timeline can be flexible. The budget for this project is a fixed price. Freelancers are requested to include their estimated cost and timeline in their proposals.

Candidates should note that this project involves intricate real-time data inconsistencies and challenging edge cases. Prior experience with such complexities is essential for a successful fit.
