Staff / Principal Software Engineer and Software Architect

I lead architectural governance for Coupang's automation and warehouse management system ecosystem, overseeing a cross-functional group of more than 15 engineers and data scientists.

I spearheaded the architecture for the Coupang Compass AI Agent platform, including CI/CD quality gates and smoke tests that increased delivery velocity by 50% and reduced deployment failures to under 1%. I designed intent-recognition and OCR-normalization services for over one million daily-updated SKUs, achieving 99.9% cache hit/message accuracy and sub-100ms p99 latency. I also led integration of cobots, ForwardX sorting robots, and AI camera systems through edge-cloud orchestration, improving sorting efficiency by 10% and packing throughput by 30%.

I led the re-architecture of Grab's merchant platform and managed a team of 12 backend engineers across Singapore and Beijing.

I transformed a monolithic merchant system into a domain-driven microservices ecosystem serving more than one million merchants across Southeast Asia, reducing feature delivery lead time by 40%. I also re-engineered the food-delivery scheduling engine using a custom time-wheel algorithm, reducing resource overhead by 20% and improving peak on-time delivery KPIs by 20%. I established coding standards, architecture reviews, and migration strategies that supported zero-downtime partner integration and order-management cutovers.

I designed image categorization and bulk-import pipelines for global user content.

I also architected integrations for WeChat Public Accounts and third-party advertising APIs, supporting content and advertising platform capabilities.

I architected promotion and recommendation web widgets deployed across Amazon marketplaces in China, the United Kingdom, France, Italy, Germany, and Spain, supporting multi-million-dollar revenue funnels.

I designed a configurable workflow engine for AWS China's internal business management platform, automating complex approval chains across more than 50 departments.

I held progressively senior engineering and architecture roles across global technology organizations, developing expertise in enterprise software lifecycles, security evaluation, cloud infrastructure, data platforms, and legacy-to-cloud migration.

At Microsoft, I built contract approval systems that generated approximately $2 million in annual savings across 130 countries. At Huawei, I developed VM monitoring and log-analysis modules for CloudECO. At IBM, I designed cloud APIs and service-provider components for IBM Smart Cloud. I also contributed to microservices decomposition for Chanjet SME finance platforms serving over 100,000 enterprises and built data-warehouse extensions for Reuters Xtra3000.
