I will help to build pyspark notebooks and optimize jobs

Is your PySpark job taking hours? Is your SQL query timing out?

I will find exactly what's slowing it down and fix it.

I have optimized PySpark jobs processing billions of records in production environments. I know exactly where to look.

What I fix:

• Slow PySpark transformations and actions
• Partition skew and memory issues
• Inefficient SQL queries on large datasets
• Spark configuration tuning
• DataFrame optimization and caching strategy

You share your code. I analyse, fix and explain exactly what was wrong and why.

Message me first with your problem. I will tell you honestly if I can help.
