About

I’ve been writing JavaScript since it was popularly known as DHTML and had an alternative language VBScript to code in. Have written server-side JavaScript with ASP, WSH, HTML Applications (HTA), and more recently in the browsers for large-scale applications and on the backend using Node.js. I have over a decade of experience working with software development, with experience ranging from PHP/MySQL and Adobe Flash back in the old school era to creating and scaling stateless applications on the cloud today. My recent focuses have been programming in Rust and working extensively with rich text editing using Tiptap and ProseMirror. Tech Experience: Haskell, Rust, Ruby on Rails, Typescript, JavaScript, Node.js, PostgreSQL, Vue.js, GraphQL, ProseMirror, Tiptap
