I need an experienced engineer who can sit with me in Pune offline and provide hands-on, offline technical support for daily software-development tasks. (entire month but as per both convenience) The focus is strictly on Python and PySpark: reviewing code, optimizing Spark jobs, and guiding me through best practices as we build and maintain data-processing pipelines. This is not a remote, on-call role; I’m looking for someone who can be physically present—pair programming, white-boarding solutions, and helping me push features all the way to a clean commit. If you have solid production experience with Python, strong command of PySpark’s RDD/DataFrame APIs, and the confidence to troubleshoot performance issues on the spot, let’s talk about a regular schedule that works for both of us.
