Ruby is the language that builds the Rails and many awesome frameworks, libraries and tools (like Brew). I start using Ruby in 2010 and totally fall in love with the language. I have used Ruby since then to solve client's problems, automate things and improve my coding skill.

K’vin walked me through getting a ci/cd pipeline pushing java code to a host in jenkins from start to finish. He is very knowledgeable and was able to quickly get me up to speed on the setup process

I asked K'vin to help me with my project and he was patient and walked me through my specs. He pointed out where my tests were failing and guided me to fixing them.

Man, what can i say. I had this dev ops issue that was very difficult, and went through a lot of mentors who threw their hands up. Kevin however, was very persistent, detail oriented and skilled, and we were able to knock down problems one by one until we got it fully working! it was LONG session and a very difficult one but Kevin got it done, and I just gotta say - I highly recommend this mentor for your issues.

Rails Migration overview

Many times when I talk about MVC in Rails, people will ask then what is the migration. I think I could write a blog thats some how explain the Rails Migration using my words instead of the officical Rails guide. The blog isn't for a replicating the Rails Guide, it covers the main concepts of Rails Migration using my language.

This engine handles storing all of the availabilities of each properties in a far futures. This engine is designed such that it can handles 8 thousand requests at the same time, each request can enquiry a list of properties and the range of time. The engine updates its data using a few different strategies. Those data that is sent from other platform or different application, I have designed a queue system to async update. However, for many different platforms, they don't have a way to do that. Our app needs to update for every window of times. At the time the project is live, there are 44 milion of data points the engine manages and serves to other products every seconds.
