From Chicago, completed MSc in Data Science 6 years ago in Scotland. Hobbies include sports, data, and programming. I am at an intermediate level of coding in Python and have mentored various python beginners that I have met through Facebook groups, StackOverflow, junior Data Scientists on my team, and new MSc Data Science students . I work with many of the machine learning packages in Python such as scikit learn, keras, TensorFlow, various python visualizations, NLP, computer Vision, etc. Alot of what I like to do in my spare time is collect data via web scraping techniques, or with automated browsers, to utilize in machine learning workflows. I have three philosophies: 1) First just get it to work, THEN if need be, get it to work fast. 2) Don't try to boil the ocean (don't try to solve an entire problem on first go, break it up into smaller simpler tasks, then you can embellish and add on. 3) You don't need to memorize everything, but you should be able to be resourceful enough and look it up/Google it. Find examples or tutorials that exemplify what you are trying to do, or the issue you are having, and adapt it to your personal needs. Lastly, here is a video of a talk I gave at conference describing my MSc project. https://www.youtube.com/watch?v=Z3rbo3WoMME

I have experience as a Data Engineer, Machine Learning Engineer, Organization/Process designer, and Team Leader. I'm looking for part-time work while pursuing personal projects connected both to software and organizational theory. My focus is on Python and Scala, even though I have professional experience in several different languages that I can brush up on if needed. I have plenty of experience in translating business needs or research code into actionable requirements. This includes first and foremost effective communication skills, mediation, and facilitation of meetings. If it's of interest, I can bring to your organization more effective meeting practices and review your process and practices around software development and decision making. I'm also proficient in prototyping and software for internal use, using no-code tools like Notion or Airtable and automation suites like Zapier or n8n.
Done a heck of a lot of programming and software design since I wrote my first on a Sinclair ZX spectrum in 1987. Not enough of it has been made open source. 2000+ five star ratings
