I'm building and enhancing market data pipelines at Quadeye Securities for global exchanges including KRX, HKEX, TAIFEX, CFFEX, and OKX. I've migrated Korea market data storage to Amazon S3, resolved historical pricing inconsistencies, and diagnosed 15+ production issues across ingestion and processing workflows.
Previously at Carousell, I created migration and API-update automation that eliminated nearly all manual effort, while refactoring API endpoints to improve response time and developer workflows.
At Wingify, I developed Java Spring Boot REST APIs for contract management with Salesforce integration and automated email notifications, reducing manual effort by roughly 60%. I also built a notification system with retry logic and logging.
I'm a competitive programmer with 1100+ solved DSA problems, a Codeforces Specialist, and a CodeChef 4-star competitor. I also built Pixy, a C++ chess engine using Minimax, alpha-beta pruning, quiescence search, iterative deepening, and move ordering.
