About Me


Hi, my name is Christophe Kalenzaga and I’m a software development engineer from France.


As far as I remember, I’ve always used computers. I began with the MS-DOS commands to run video games when I was 5. At 12, I started learning BASIC because I wanted to make video games. After I realized that I could only make some screen text games, I stopped. At 14, I created a static web site in HTML and then started learning PHP/MySQL but I stopped after a few months. It’s only during my Master’s degree in CS that I resumed programming.

When I was student, I worked on very interesting projects like


I’ve been working in IT since 2010 and I’ve worked on multiple technologies:

  • C/C++ (a little bit)
  • Oracle 10G and DB2 9.7 (I’ve done a lot of SQL queries and some database optimizations)
  • I’ve been working with ETL (Informatica then Ab-initio which is way better).
  • During 3 years, I’ve worked a lot with Java and Spring (which I really like)
  • At the end of 2014, I started working on Big Data (Hadoop, Pig, Hive, HBase, …)

My main interests in IT are:

  • algorithms
  • distributed systems
  • software craftsmanship


I decided to start this blog in order to share my passion with people like me and to improve my knowledge.

I hope you’ll enjoy it.
