I'm Johan, I've been doing open source since 2016, mostly in the Go ecosystem π». I'm currently a maintainer π¨βπ§ of:
- The Go WebAssembly Port π, allowing the use of Go in the browser and the backend.
- The gRPC-Gateway π, a HTTP/JSON <-> gRPC translation layer which is serving companies and open source projects such as etcd, Core OS, Cockroach DB, Chef and others.
I'm also a contributor π¨βπ» to:
- The Go standard library. I contributed to the creation of the
encoding/json/v2package, and I made essential contributions the WebAssembly port, where I ported the GopherJSnet/httpimplementation to the standard library, allowing the use ofnet/httpHTTP requests from inside WebAssembly applications. I also wrote many of the proposals for greater WASI support, including the wasip1, go:wasmimport, go:wasmexport and function ABI type restriction relaxation proposals, all of which are now part of the Go compiler.
I author blog posts π° on varying topics, mostly relating to Go and gRPC on my personal website.
I also frequently deliver technical talks π¨οΈ at conferences, including GopherCon San Diego πΊπΈ, GopherCon UK π¬π§, dotGo π«π·, GopherCon EU πͺπΊ, FOSDEM π§πͺ and more. I've also featured on Go Time ποΈ on topics ranging from security π‘οΈ to PostgreSQL π. My personal website contains all the recordings and slides of my presentations.
Lastly, I'm frequently helping π¨βπ« beginners and experienced users alike to solve problems with their code and setup on Gophers slack, in particular on the topics that I have specific expertise, such as gRPC, protobuf and security. I can be found in the Gophers Slack under the username jbrandhorst. Come say hi!
