Friendly, patient coach for Ruby, Python, JavaScript, Go, Data Science, Big Data, AI, Blockchain, Chatbots, React / Angular / Native. Technical co-founder of VC backed big data startup.

Ruby was my first love - the syntax is beautiful, the community is enormous, and the frameworks, whether building a big application in Rails or a simple blog in Jekyll, will get you up in running in no time. I've quickly build Ruby websites to prototype ideas and supported huge, enterprise grade, high availability, secure, distributed web applications, including various deployment mechanisms, from Heroku to AWS, Google Cloud, and Docker with Kubernetes.

Freelance Ruby developer in Tehuacán, Mexico

Expert Programmer of 15+ Years - Rails to React, Webpack and beyond

In 2008 I swapped my C# and .Net IDE and Windows box for a Mac and Ruby. Up until a year or two ago 90% of the software I wrote was in Ruby, spanning from sorting 1000s of atmospheric, seismic, solar, and wildlife reporting data from stations around the world to solar panel efficiency algorithms to countless e-commerce websites. Until I got re-hooked on JavaScript (Thanks React!) it's pretty much all I did. I know MRI inside and out and spent a long time perfecting my Ruby Fu, extending into Functional Programming, test driven development, and so much more!

Web Developer. Microsoft Excel & VBA specialist.

I started used Ruby because of Rails and I felt in love with this language. The community is mostly product-driven and the syntax is plain-English-like. I'd recommend Ruby to anyone willing to have pleasure in programming. Besides Rails, I use Ruby to scrape web pages, consume RESTful APIs, or automate simple tasks.

Senior Software Engineer at Disney-ABC TV

I've worked 9 years in professional software development, for big companies like Disney and IBM, in Java/Unix, to several small LA startups, in Ruby on Rails. I worked for the pop star in Hollywood, as the sole engineer creating our Rails APIs. We work on a wearable smartband (smartwatch + smartphone). I've also taught high school and college students over 8 years, in science, math, English, and AP Computer Science. I love teaching and think there's not enough support to help junior developers get to the next level.
