I’m a highly-motivated data scientist looking to use my skills to analyze and solve complex problems and to apply those solutions to real world situations. I recently completed the Data Science Immersive course at Galvanize in Denver, CO, a 3-month 700+ hour program covering core data science areas and skills including Python, machine learning algorithms, and data visualization. I am currently seeking opportunities where I can utilize my programming and data analysis skills in a challenging and fast paced environment.One of my earliest tech memories was custom-building my first pc with my brother. This led to a love of technology and from there a love of programming. After teaching myself Python I jumped into data science and have developed a love for it! Before the galvanize course I was a physics major at University of Colorado Boulder with a minor in mathematics, and a officer manager at Alternative Naturopathic Center. I look forward to advancing my knowledge in these fields even more!My hobbies include rock-climbing, reading, hiking, and gaming. I am originally from Colorado, but would absolutely be interested in out of state opportunities. If you're looking to build your data and analytics team, or have any questions on projects feel free to contact me!
