Hello, I just read your job posting, and it sounds like you need a Spark developer. I have developed close to 10 robust applications running in production in my IT experience. I have also completed lot of projects in Upwork as well. Let me know what kind of applications you are trying to build batch/streaming. Reply to this proposal so that we can discuss further on this.
