Tricomia-event-listener-service

built an event-listener service to track blockchain events and update order statuses in the database, enabling real-time transaction visibility. To ensure reliability, I implemented a cron-based fallback mechanism that handles missed events or server downtime, maintaining data consistency and improving overall operational robustness.

Cross-Chain-Bridge

Built a cross-chain token bridge with a burn-and-mint mechanism across chains. Developed an event listener service to monitor blockchain events and trigger cross-chain actions. Added a cron-based fallback system to recover missed events during server downtime, ensuring reliable and consistent transactions.
