Overview

Currently at Sea, where I work on data pipelines. Wrote the Spark service that now handles 34 million requests a day. Cut p99 latency on the data platform services from 528ms to 78ms. Before that: Bank Central Asia and SoftBank. Most at home with PostgreSQL and SQL. Bird-watcher and amateur naturalist.
