Hello,
I am an software engineer with more than 6 years of expereince in embedded systems development specially in raspberry pi based systems. I read though your project description and it got me interested, because I have developed some Arcade type games on raspberry pi for my hobby projects. I am also kind of lover of these types of games as well. :)
As for a solution to your project, I would like to know better about the existing setup. I believe the existing software is written using python (I am skilled in C++, Java, python and other scripting languages) .
I also have set of Raspberry pi boards to test these things, so with that resources and experience I have, I believe I am one of the best candidate to handle this project and deliver successfully.
I would like to discuss more details in the chat.
Looking forward to hearing back from you.
Thank you
Anusha
