My first job was developing and maintaining a streaming system based on Apache Flink. Thus, it's normal to me that a "full-time opensource developer" can get paid. Of course, there are some in-house tasks. But still, I spent a lot of time participating in the upstream community and became a committer after about one year's contribution. That said, after I changed my job, my engagement decreased considerably. But my following jobs are mostly still full-time OSS developers: * PingCAP for TiDB and TiKV. I wrote its dev guide and built its (new) governance. * StreamNative for Apache Pulsar. * Greptime for GreptimeDB. Many (infra) software MUST BE open source today.
