What I'm looking for

I'm looking for backend engineering roles focused on high-throughput systems, scalability, reliability, and operational excellence.

I've built and operated backend infrastructure for TikTok Object Storage, owning TMeta—the metadata control plane for globally distributed storage. I led global KV migrations, failover improvements, SDK unification, intelligent rate limiting, and multi-cloud support for high-volume international products.

Previously, I developed Shopee's Flash Sales and Voucher platforms, including cache-purging systems, production-traffic stress testing, caching libraries, and circuit breakers. At Works Applications, I built enterprise mail workflows and asynchronous contact-import systems using Cassandra and Kafka.
