I am a Senior Software Engineer from Toronto, currently working as a Ruby on Rails and React/Redux Developer at theScore Inc. I am passionate about helping and mentoring people, especially those who are new to web development and the programming world. I am specialized in explaining the core concepts of Ruby and Rails, Javascript, React, APIs and everything else along with the best practices. I focus on the learning experience of my students and make sure they get exactly what they want. I have excellent academic track records (Bachelor of Science in Computer Science and Masters in Computer Engineering from the University of Toronto) along with strong development and industry experience in Software Development and Web Development (15+ years coding experience in total).

I have helped more than 700 individuals here at CodeMentor (with 3,590+ 5 ★ sessions) with their projects implementation, bug fixes, architecture advices, performance improvements etc. I have worked with a bunch of CEOs and CTOs of YC start-ups and helped them with their projects. Made long term relationships with many of them which I help in a regular basis today.

I have helped a ton of bootcamp students here at CodeMentor and helped them build their web development career path and getting jobs after the completion of their bootcamp cohorts.

Here at CodeMentor, I have helped people from all levels: From someone who is brand new to programming to 30+ years of experienced Senior Software Engineers, Product Managers and everyone in between. It's been an amazing journey here at CodeMentor for the last 8+ years! :-)

I started programming and solving problems in 2006, at the age of 18. Since then, I wrote programs in a variety of programming languages such as C, C++, Java, PHP, Ruby, Python, Javascript, etc. These days, I use Ruby and Rails and React JS as my primary programming languages and frameworks.

I can help with debugging your issues as well as refactoring your code according to the best practices and conventions out there. Helping people is my passion and motto in life. If you think I can help you in any way, please get in touch!
