Planning to work on

• Jest compatibility with Node16 and .js imports in jest.config.ts jestjs/jest#13350
• Writing some primer on how to setup monorepos with TypeScript
• Writing a guide on how to write NestJS modules using some particular techniques

Past contributions

I'm usually trying to contribute to tools that I use on a daily basis, if not via PRs, then at least trying to file bugs and reproduce them.

Recent work
