Is this a CV? Logbook? Highlights? Maybe a bit of all. Currently hired by Postman, as part of their Open Technologies Team, as a Lead Software Engineer working on AsyncAPI full time.

GamingAPI.org is a side project of mine where I try to use everything from AsyncAPI (tooling and spec) and incorporate it into a standard for interacting with all types of game servers (focus on Rust, upcoming Minecraft, etc.) through generated SDK's, documentation, governance, and more! |
Here are all the tools I am actively maintaining regardless of what my day job is.

Here is a list of all the previous libraries and projects I have worked on.
- https://github.com/jonaslagoni/Wizard-Of-Treldan, university group project, 2d and 2 different UI games in one, with a custom game engine, written in Java.
- https://github.com/jonaslagoni/NEON, university group project, a 2d tower defense game, using OSGi to use a modular system to load and unload towers, maps, game modes, etc on the fly, build upon libgdx, written in Java.
- https://github.com/jonaslagoni/csgoLiveServer, spare time project trying to reflect what happens in a CSGO server in the web browser, first version of GamingAPI I guess.
- https://github.com/jonaslagoni/asyncapi-quicktype-template, AsyncAPI generator template to generate typed models with QuickType.
- https://github.com/jonaslagoni/asyncapi-quicktype-filter, the core library code for the QuickType template.
- https://github.com/jonaslagoni/.NET-websocket-client-template, an old AsyncAPI generator template for generating a WebSocket wrapper in .NET.
- https://github.com/jonaslagoni/ts-websocket-server-template, an old AsyncAPI generator template for generating a WebSocket wrapper in TypeScript.
- https://github.com/jonaslagoni/Java-to-JSON-Schema, a JSON Schema draft-7 DSL for writing JSON Schema through code in Java.
- https://github.com/jonaslagoni/Java-to-AsyncAPI, an AsyncAPI DSL for writing AsyncAPI documents through code in Java. Uses the JSON Schema variant as well internally to define payloads.
I am using eventstack.tech/posts as my personal sanctuary for writing stuff about the projects, updates, and different tech stuff.
Here is an overview of the subjects so far:
- Automated code generation (introduction, versioning, for TypeScript libraries, for .NET libraries)
- AsyncAPI Governance (getting started, in practice part 1, part 2)
- API versioning (theory, in practice)
- Reusability in AsyncAPI causing problems
- AsyncAPI tooling updates (week 30, 33, 39, 46)
This section is more for me than you, trying to keep track of what I am participating in or have.
