ABOUT ME
Seasoned Software Engineer - Ruby on Rails, JavaScript & TypeScript
Seasoned Software Engineer - Ruby on Rails, JavaScript & TypeScript
Hi, I'm Delon. I've served as a software engineer, analyst and product designer for over 20 years. I've been tinkering with computers since I was 10 years old and have been engrossed in math, computer science & learning the art of computer programming since I was 15. When I was 18 I got my first professional programming job automating a data conversion for my mother's client.
I enjoy solving business and organizational problems through good communication and just the right amount of art, science & technology. I specialize in designing and building data-oriented systems like scheduling systems, workflow systems, and form systems. I also enjoy graphic design, systems programming & integration, automation, working with arcane data formats, and building compilers and interpreters.
Though I'm comfortable with a wide variety of technologies, most of my work is with Ruby on Rails, JavaScript (including TypeScript) & Clojure. I've also been gaining experience with Natural Language Processing.
Besides computer science my other passion is mentoring & teaching. I've tutored students in math, science and engineering since high school, both professionally and as a volunteer, and have mentored programmers as a team lead, on platforms like CodeMentor & through my own connections.

Started with Ruby on Rails before version 1.0--stopped using Rails for a while but continued using Ruby with Sinatra and other libraries, for scripting tasks and creating web and CLI applications. Have been using Rails quite a bit again in the last 4 years or so.

Like most developers of my time I used it early on to sprinkle interactivity on web pages, but eventually I took it seriously as a language and came to like it quite a bit. Have built multiple SPAs, used Node.js for systems programming, web backends and CLIs. Have built complex applications with the help of various JavaScript libraries like jQuery, React, and Express, but have also done so with vanilla JavaScript. Have made use of various compile-to-JS languages like CoffeeScript, ClojureScript, and TypeScript. Have implemented some of my own compile-to-JS languages.

Have used relational databases in a wide variety of applications, many of which in healthcare which have often required reasonably sophisticated database modeling and querying. These days mostly use PostgreSQL or SQLite.

Built a workflow system with scheduling and EHR features whose backend was implemented in Clojure and Datomic. Currently working on a Rails application that has two micro-frontends implemented in ClojureScript. Have used it for scripting, and various complex system integration tasks. Have created my own implementation of the language.

Got my start around 1999 at 18 years old writing a data conversion script in Perl for a client in the manufacturing industry. Clients have included small businesses, universities, and large organizations (e.g. The Department of Veterans Affairs, Time Warner & Master Card) across industries (e.g. retail, marketing, health care, education, research, non-profit) in Connecticut, Hawaii and New Mexico. Built everything from small websites, and console applications to large multi-tier systems. Advise business leaders. Have come to specialize in systems integration, business process management, and data-oriented programming.
