I'm a Python and Java/Scala developer, with main focus on Big Data solutions and some full stack web dev experience. I will happily look at your code or system and point out bugs or suggest a better way to do something. Have experience with most popular Python libraries including pandas, matplotlib and numpy. If you want a great code review/refactoring of your Python code, from which you are going to learn and improve as a developer, I am the person to go to. If you have a data transformation that is taking ages, ask me for my help. I have been able to achieve speedups of up to 500x for people here, by using libraries such as pandas in an optimized way and being aware of memory usage patterns. I also am particularly well versed in geospatial data management and the open source project QGIS. I'm a big fan of clean, testable and tested code with a wow factor. I'm also striving for automating everything with the correct tools. I have also worked at Google. I love consulting people via codementor. So far I have walked people through building web apps in Python, solved tough bugs in complex systems and shared my expertise in designing data pipelines. I also have, among other things, helped parallelize code that analyzes DNA sequences, configured git servers and showed people how to get started with unit tests.

Python is my best language. I have used it to build complex data analysis pipelines and also for data science to employ and evaluate models (to draw insights out of big datasets) Here is an article I have written on the topic: https://www.airpair.com/python/posts/top-mistakes-python-big-data-analytics

Karolina is a wonderful mentor. She very patiently listened to my challenge and was quick to comprehend it. She then walked me through an elegant and skillful solution, while sharing some extra pointers about Python and Pandas along the way. I'm so grateful to have worked with her and look forward to future collaborations.
