I'm a **polyglot fullstack software developer** (*I'm able to effectively work with multiple languages, tools, and frameworks*) with over 13+ years of industry experience in web application development. I'm also an instructor and mentor in various bootcamps having lead class cohorts, mentored groups of students and 1:1 tutoring sessions. I'm experienced in **Python**, **ECMAScript** (Javascript or Node.js), **Java**, **C#** **Ruby**, **PHP**, and even **Scala**. I work in both frontend and backend spectrums of the web stack, so whether you're debugging something in React.js or you're stuck on a complex SQL query, I'm more than happy to help in your code debugging adventures.
My instruction style is that I like to guide the student towards learning *how* to solve rather than simply giving you the solution - I don't believe a student should be stuck on always referring back to a senior developer to get unblocked, but should be empowered to solve their own problems. Now that's real mentorship!
