Engineer with Ruby on Rails, Python, .Net, JavaScript Skills and More...

Mark is a professional software engineer with 16+ years experience, recently branching into mobile development (iOS, Android, and React Native/Mobile).

He works with Ruby, Rails (and other Ruby frameworks), Python (Django since pre-1.0), JavaScript, Node.js, React, Redux, C#, Java, C++, C, Objective-C, Swift, Angular--and don't forget Unity3D. What he does not know, he learns quickly and implements even quicker.

His favorite part of the job is the constant learning and he loves to contribute to open source projects. He is the author of several RubyGems (Taggregator and Clortho being the most popular) and submitted a bug fix that was patched into Rails core.

With Rails, I've built everything from next-generation control room software for ConsolidatedEdison (the NYC power company) to a platform that handles logistics and scheduling for sharing expensive medical equipment among healthcare facilities and systems that provide nationwide property listings/MLS data for Real Estate professionals. I've been using Rails since 2005 and have developed many applications that are still in production.

Python was one of the first major scripting & programming languages I taught myself after formal schooling. I have used Django and other Python web frameworks in professional and side-projects. I still use Python as one of my development (DevOps) languages of choice and Django when clients request it. I currently mentor students and professionals online via Codementor and teach Python programming and web development courses (offline, in-person) for University and Professional audiences.

I've been using JavaScript since it was born. Back in 2004, I had a conversation with a friend over coffee in NYC and I proclaimed that JavaScript would be "the one language to rule them all." My prophecy has arrived. So have my JS skills. It's a weird, wild, wonderful technology landscape and I love it. I live in it daily.

Learned Ruby alongside Python and have been using it for scripting tasks, web apps, mobile development, and pretty much everything under the sun since then. I love the expressiveness, concsiseness, and elegance of the language itself and find it highly productive and powerful for many daily tasks.

Early adopter of NoSQL technologies and Mongo was one of my favorites. Authored a couple rubygems to help earlier Mongo instances aggregate tags and sort and collect keywords. (Clortho and Taggregator)

I have been building mobile apps since before the app store or Google Play existed! I started programming Windows Mobile (I know that will date me!) and continued developing native apps for ios (Swift and Obj-C), Android (Java), and Windows (Xamarin, C#). I also do backend development and integration with third-party APIs. I know apps. I <3 apps!
