Hi there 👋

🔭 I'm currently working on Digital Twin for Digital Substation Communication Networks
📡 I'm part of @midiacom and @FriendsLabUFF
🌱 My interests are:
- Python (mainly communications, sockets and protocols) and Linux;
- Smart Grid (IEC 61850), MMS, GOOSE and SV;
- Digital Twin, Digital Substations and SDN (Software-Defined Network);
- I also research 5G sometimes.
🤔 I'm looking for help with Python speedup (probably with Rust)
💬 I can help you with: Python and IEC 61850
📫 How to reach me: [email protected]
😄 Pronouns: he/him ♂️

Here follows some of my opensource work:

**TL;DR** [`__repr__`](https://docs.python.org/3/reference/datamodel.html#object.__repr__) should help us recreate an object even if it has random behaviour or if it changes itself during runtime. Check the final [Deck Class](https://gist.github.com/arthurazs/2a9e7ec13cbc18edc19195fb2f224622#file-2_final_deck-py).
