    I have been writing various python programs, scripts, and utilities for 8+ years mostly as a hobby. I have written several small programs in relation to databasing (mysql, sqlite3, postgres), desktop computing, web development (django). I do have a few paid programming jobs under my belt but programming has foremost always been a hobby for me. I'm looking to see if my years of experience and skill can be put to good use. I am very proficient in general computing with Windows and Linux with little experience with macOS. I see every job as a personal challenge and aim to write the best professional code to my ability.  less
