Most Recent Review

This is a really solid course, even in 2026! Yes, its a bit dated but Ruby/Rails hasn't changed much and fellow students have solutions for most road blocks. I would have loved to see a more robust intro to Ruby section. What's here is just enough to be decent at Rails. That said, the course includes a lot of aspects of Rails features, along with version control using git, pushing code to a remote Github code repo, deployments (would love to see an alternative here) and in-depth testing, which isn't typical on most courses. I'd recommend this course for sure!

Instructor Bio

Hi, I'm Mashrur, I'm a full-time programming instructor specializing in programming fundamentals, web application development, machine learning and cyber security. I have been a technology professional for over a decade and have degrees in Computer Science and Economics.

My niche is building comprehensive career focused technology courses for students entering new/complex and challenging fields in today's technology space. This is a nice segway for me, since my real passion is building and tinkering with programming languages. I love everything to do with development and learning about new tools and technologies. My favorite languages are Python and Ruby on Rails, and my favorite tech fields are web app development, machine learning and data-analytics (which is where Ruby on Rails and Python fall into place nicely). I encourage my students to focus on these technologies as well.

In my past (corporate) life, I worked with Enterprise Software Systems with roles played in analysis, development, management and training. I led projects using both agile and waterfall methodologies and thus am well versed in the inner workings of the software development and delivery world. 

During my time in corporate America, I realized how much I enjoyed training new hires and new team members and helping them succeed. I dedicated a good amount of time over 7 years on-boarding new analysts and developers and then worked with them to build and maintain systems which put me in a unique position to know and understand what new entrants to a field need in order to succeed. I strongly believe in focusing on fundamentals and practice; and not in shortcuts or gimmicks. 

So join me for my comprehensive career-focused technology courses as I guide you through the world of web application development, machine learning and cyber security using Python, Ruby on Rails, MySQL and others and bringing your ideas and passions to life.
