Location:Cape town. Remote: Yes. Obviously. I don’t do office culture. I prefer quiet dark room with a 4K monitor and a mechanical keyboard. Willing to relocate: Only if the relocation involves a data center, a hackerspace, or a country with no extradition treaties. Otherwise, no. Technologies:Go, Rust, C, C++., Docker, FreeBSD, and I once fixed a mainframe. Don’t ask how. MongoDB, I’ve written my own key value store
“It was really slow and the data in there was all buggy.”
“I manage a few MongoDB, PostgreSQL clusters.”
“I loved MongoDB's query language but grew too frustrated with the actual runtime”
“Data: MongoDB for users/listings/events, S3 for assets”
“I love MongoDB's query language (JS/Node.js developer so the syntax fits my mental model well), but running a production replica set without spending tons of cash is a nightmare.”
