I’m currently working as an Erlang/OTP engineer (10 years+), though I'm also into Elixir and have experience working with it (2 years+).

I try to use some of my free time to contribute to Free and Open Source Software, especially in Erlang and Elixir, but sometimes also in tools supporting generic development.

Search for Paulo F. Oliveira in the Erlang Ecosystem Foundation Slack. I'm usually open to a chat, especially if Erlang and/or Elixir -related.

These are the GitHub organizations I belong to, where I (co-)maintain projects:

• "org." starbelly
  • rebar3_ex_doc - rebar3 plugin for generating docs with ex_doc
• org. 2Latinos
  • nuntius - An Erlang/OTP library to mock registered processes
