At Independent, I built two end-to-end analytics engineering projects. My SaaS subscription project uses dbt and BigQuery to create an MRR bridge from raw subscription events, with 119 tests and pull-request CI that builds in a throwaway dataset. I also built a Seoul apartment sales ELT pipeline that loads government open data into BigQuery and models it as a tested star schema. Previously, at Bory.ai, Ltd (보리 주식회사), I worked on client and internal products, including reducing Saysame’s Firestore reads by 80% through client-side caching and changes to data access.
