I would like to recommend @rafaelhlima as the first Brazilian Portuguese community liaison.
During the last year, Rafael has worked with bug fixes (UX/UI and dark mode related) and some few feature developments (improvements in the Basic IDE and save solver settings in Calc):
He also worked in minor fixes in help pages and documentation and did some QA work in Bugzilla.
Rafael is active in the Brazilian and the global communities. He presented a workshop about Python scripts with ScriptForge in the LibreOffice Latin American Conference 2022. He also presented about the same topic in the LibreOffice Online Conference 2021:
Python scripts in LibreOffice Calc using the ScriptForge library
Finally, Rafael, as an experienced professor (a great skill in his job), is always available to support and teach new members.
I hope he can accept this recommendation for the Liaison role, as a recognition of his past contributions and an encouragement for the future!
