Overview description still in progress, as main topics I like to work with are:

• Frontend: JavaScript & TypeScript, Performance (Lighthouse, Web Vitals, ...)
• Tooling: CLI implementation, CI/CD (GitHub Actions), GraphQL...

Last months collaborating in some Open Source projects. The one with more activity is Octokit (libraries and utility tools to interact with Github's API): docs.github.com/en/free-pro-team@latest/rest/overview/libraries

What's coming next? Plan to get expertise into React
