Profile: https://flows.cv/arthurcronin

After graduating with a BS in biophysics, I worked at Applied Materials for 5 years as a process engineer. In 2022 I decided to pivot to SWE and completed a Python/JS bootcamp. With a strong scientific and technical background, years of real-world experience, and new found coding skills, I am eagerly searching for the right company and role to begin my new career. In the meantime, I enjoy honing my skills with personal projects and learning new (coding) languages.
