Spring Boot app that transforms and stores real-time TCP/IP messages into csv files

I'm looking for someone that will be willing to build the following Spring Boot app that, 1) after some minor treatment on the formatting of real-time financial market data submitted through a TCP/IP connection, 2) starts to store it into various csv files, 3) according to customized commands run at the terminal, 4) that basically set parameters and make multiple actions over existing commands provided by the data vendor. There will be more things related to this project in the future. This app will be part of a financial analysis platform that I'm building little by little. At the same time this is being built, I'm also learning Java (and Javascript) myself, so I'd be willing to learn from your experience by studying your code. I don't intend to be a programmer, but rather have a good understanding of what is happening under the hoods (lots of comments in the code won't seem wordy to me at all). If you are interested, please find attached further details. The document is divided in 3 sections. The first is intended to give you some more technical details on it. The second gives additional technical details on naming conventions, formatting, message protocols, etc. The third section is just an Appendix with something very specific about data types. Just so you know, the next step of this project will be related to: 1) streaming these events into a message broker (RabbitMQ or Solace - the latter highly used by large financial institutions), 2) storing this information into a time series database and 3) websockets. It would be great if you could also work on these, but that's not a requirement. I'm hoping to find someone that can join me on this journey.
