Looking for a Big Data engineer

Looking for a big data developer proficient in python and pyspark to help me to optimize the spark stand-alone cluster configuration I have some issues doing inference using a deep learning model. That I do an inference-trained deep learning model in a distributed manner using multiple nodes based on a spark stand-alone cluster, and I need someone to discuss with him my result and review some issues that are mainly related to Spark not using all configured storage memory capacity.
