About me

Hello! My name is Calvin K. Sierra. I like to travel, program and spend time with benefit. Also interested in music, teaching, foreign languages.

On the pages of this blog I take notes, write on various topics and share my experiences. Travel enthusiasts will love the travel section, and for programming learners there are sure to find useful blog articles by category.

Since childhood, more than 10 years. In the last 6 years I have been mainly engaged in backend development, I use PHP in my work. Certified Zend Specialist.

I work

Currently, I am working with Infopulse, developing a product for analytics and monitoring the quality of services for a customer from Germany. I like!

I travel

During my life I managed to visit Poland, Bulgaria, Hungary, Slovakia, Slovenia, Montenegro, Italy, Spain, Germany, Austria and the Vatican. And Iā€™m not going to stop there, even the wish-list was šŸ™‚

Another thing I devote the lion’s share of my time to is the PHP Start educational project. This is a free 15 hour web development basics course. According to some, even your pet will learn to program with this course.

Teaching

I teach at Infopulse Univer. I sincerely believe in the business I am doing.

Music

It can be said that the project listen-radio.org I have been doing since the very beginning of my professional career. Unfortunately, the site does not always have time, but recently, my girlfriend Anya helps a lot!
