## Who I am, and what I work on

I am **Ruohang Feng**, generally known online as **Vonng**. I build databases,
I run databases, and I write about databases.

In 2018 I started [**Pigsty**](https://pigsty.io) — a battery-included open
source PostgreSQL distribution. It packages high availability, point-in-time
recovery, connection pooling, a full monitoring stack and four hundred-odd
extensions into an RDS you can run yourself, so that anyone can have
cloud-database capability on their own servers without paying the cloud premium.

Before that I worked as an architect, DBA and full-stack engineer at
**Alibaba**, **TanTan** and **Apple**, where I ran hundreds of PostgreSQL
clusters and made most of the mistakes worth making.

Outside of work I translated [**DDIA**](https://ddia.vonng.com) (*Designing
Data-Intensive Applications*) and [**PostgreSQL
Internals**](https://pgint.vonng.com) into Chinese, maintain
[**pg_exporter**](https://pigsty.io/docs/pg_exporter) and a handful of other
open source tools, and keep writing here.

I also hike, travel and play games. Those show up in
[Travel Notes](trip/) and [Miscellaneous](misc/).
