Python expert for Data Applications & Web Dev
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.
