Overall experience in Python (pandas, bs4, selenium, multithreading and multiprocessing ) & MSSQL/T-SQL (procedures, triggers, and functions programming for data-flow automating): 3,5 years.

Developed 2 years ago (refactored a year ago) and yet supported and "feature-added" (mostly monitored) web-crawling "monster" and data-processing system, built with Python27 (and SQL-Server (as the side effect of data processing and storage needs)).
I'd like to make the world better: e.g. automate as much stuff as possible. I do better prefer to automate some data-driven processes. Have never been working with DS and ML, it would be nice to gain such experience. >>>remote might be possible in PL<<< >>>Full time on-site - Warsaw area only<<<. *I respect, but do not believe in the corporate rules or beliefs... all I believe in - is that the job needs to be done.
