Hello 👋

I'm Johan, I've been doing open source since 2016, mostly in the Go ecosystem 🐻. I'm currently a maintainer 👨‍🔧 of:

• The gRPC-Gateway 🌉, a HTTP/JSON <-> gRPC translation layer which is serving companies and open source projects such as etcd, Core OS, Cockroach DB, Chef and others.
• Go gRPC Middleware 🥪, a collection of interceptors that add logging, metrics, tracing, authentication, retrying logic and more to your Go gRPC servers.
• Improbable's gRPC-Web 🕸️, a project that brings gRPC to the browser and implements a pure Go gRPC-Web proxy that can be used in-process with your gRPC server or as a standalone proxy.
• TinyGo 🖨️, a project that aims to bring Go to micro controllers and WebAssembly.
• Certify 👨‍⚖️, a Go in-process certificate manager that automatically issues and renews certificates for your application.

I spend several hours a week of my spare time responding to issues and writing and merging PRs and creating releases on these projects. If you've found my work useful and you want to say thanks, you're welcome to sponsor me to show your appreciation.

I'm also a contributor 👨‍💻 to:

• The Go standard library, especially the WebAssembly port, where I ported the GopherJS net/http implementation to the standard library, allowing the use of net/http HTTP requests from inside WebAssembly applications.
• gRPC-Go, the official gRPC library for Go.
• Golang protobuf, the official Google Protocol Buffers implementation for Go.
• GoGo protobuf, a third party Google Protocol Buffers implementation for Go that includes extra features such as automatic time conversion, faster marshalling and more.

If you've found my contributions to these repositories helpful, you're welcome to sponsor me to show your appreciation.

I author blog posts 📰 on varying topics, mostly relating to Go and gRPC on my personal website. If you've found my posts to be helpful and you want me to keep making them, you're welcome to sponsor me to show your appreciation.

I also frequently deliver technical talks 🗨️ at conferences, including GopherCon San Diego 🇺🇸, GopherCon UK 🇬🇧, dotGo 🇫🇷, GopherCon EU 🇪🇺, FOSDEM 🇧🇪 and more. I've also featured on Go Time 🎙️ on topics ranging from security 🛡️ to PostgreSQL 🐘. My personal website contains all the recordings and slides of my presentations. If you've watched one of my presentations and found it helpful, you're welcome to sponsor me to show your appreciation.

Lastly, I'm frequently helping 👨‍🏫 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. If I've helped you and you want to say thanks, you're welcome to sponsor me to show your appreciation.
