Over the last 15 years, I've worked as a teacher, a support engineer, a data engineer, and a software engineer. In all that time, the most engaging and satisfying work was always helping other people learn and overcome challenging issues. I have professional experience with the following languages/technologies: * Python * Java * Bash * Web (HTML, CSS, JavaScript/TypeScript) * SQL (multiple dialects) * Korn * Perl * C * Android * Docker * Linux * Git I've developed everything from simple scripts that automate repetitive tasks, to ETL pipelines, to full stack web applications (the API and backend services, as well as the HTML/CSS/JavaScript frontend), and along the way I've mentored engineers, students, and non-technical people wanting to level up their skills.
