WORK EXPERIENCE

Backend Developer, Paradise-Soft, June 2022-May 2023

●Participated and deployed a scheduled backend service responsible for retrieving daily betting records, performing settlement calculations, and generating report data. Utilized Apache Kafka as a message queue to ensure reliable and decoupled data streaming. To address concurrency issues in a high-throughput environment, implemented locking mechanisms during data writes to TiDB, ensuring consistency and preventing race conditions — resulting in a 75% reduction in data inconsistencies and race condition-related errors. Finalized data is stored in TiDB for downstream reporting and analytics.

●Participated in a scalable big data query system providing RESTful APIs for financial and operational reporting. Integrated multiple data sources (MySQL, TiDB) and implemented a layered architecture including controller, service, and repository. Supported load-balanced deployment with CI/CD pipelines across DEV/UAT/Production environments. Followed Git Flow for version control and team collaboration.

Software Engineer, Bravo iDeas Digital, May 2020-October 2021

●Designed and implemented a backend service on AWS that handles real-time XML data exchange between an e-commerce platform and logistics companies. Utilized Apache Kafka as a message broker to manage and stream XML data in real-time, ensuring scalability and decoupled communication. Leveraged PHP for XML parsing and data handling, storing shipment details in MySQL, and used JavaScript/jQuery on the frontend for user interaction. The system also integrates with an SMTP mail server to notify users upon shipment confirmation, resulting in a 50% reduction in customer inquiries related to shipment status.

●Designed and implemented a real-time streaming integration system that embeds Facebook Live directly into our platform. Leveraged the Facebook Graph API to dynamically retrieve video IDs and stream metadata. Live chat messages from the Facebook stream were continuously fetched, normalized, and then relayed to our internal chat system through a WebSocket server. The messages were also stored in a database to enable chat replay during video playback, contributing to a 40% increase in viewer migration from Facebook to our platform.
