I'm Auxten Wang, a database engineer and open source builder based in Singapore.
I created chDB — an embedded ClickHouse engine that lets you run full OLAP SQL anywhere without infrastructure. It started from a simple need: running ClickHouse in Jupyter Notebooks for ML model training instead of waiting on slow Hive clusters. chDB was acquired by ClickHouse Inc. in 2024, and I now work there full-time growing the project and its ecosystem across 7+ language bindings.
Before ClickHouse, I was Principal Engineer at Shopee, Cofounder & CTO of CovenantSQL (decentralized BFT database, 1,500+ stars), and RecSys & Infra Director at 4Paradigm. Earlier in my career, I was Technical Director at eLong, built cluster control for 30,000 servers at Qihoo 360, and created Gingko — Baidu's P2P dataset distribution system — writing 90% of the C++ code. Started my journey as an intern at Douban in 2009.
Lately, I've been exploring the intersection of databases and AI agents — building memory systems, RAG pipelines, and MCP integrations powered by ClickHouse.
