At Freelancer, I architected and developed a portal for WestUrban Group to improve customer opportunity handling, construction project monitoring, and requirements tracking. I also provided consultancy on moving data pipelines and datasets to Tencent WeData, then led a team of nine engineers refactoring BI ETL pipelines with managed Airflow.
At MagicEden, I built a parser for Solana trading events and REST APIs for real-time and historical candlestick data. The APIs reached availability above 99.95% and supported up to 200 requests per second.
At CloudKitchens, I worked with a global team on a platform integrating online food ordering systems. I led three developers in increasing integration-service availability in Southeast Asia, Japan, and Korea from 60% to over 99.95%, and led two developers in building an offline coupon-processing service.
Across roles at Wish, Amazon AWS, Shopee, Microsoft, EMC, and Ctrip, I contributed to search and data systems, payment platforms, AI services, document applications, and travel products. My work has included building ETL and ingestion services, designing system migrations, and developing backend services across cloud and distributed-system environments.
