September 2010 - Present, Sendai, Miyagi, JP
|October 2010-December 2011||Acted as a Scrum Master
I worked for a Scrum Master in a project that migrating data warehouse from RDBMS to Hadoop.
Also worked daily operations such as data extracting, researching about data, answer inquiries from other department, and so on.
I and our team modified and wrote a lot of HiveQLs(SQL-like language for Hadoop) there.
Our group was distributed on Sendai,Tokyo, and Osaka. I am in Sendai from this time.
This time in these 3 region, only Sendai was running Scrum.
At first time Sendai was like subcontractor of headquater(Tokyo), but thanks to Sendai's team's effort finally we are same team.
|January 2012-August 2014||Acted as a Product Owner
Sendai team got freedom, so I produced some systems and tools there as a Product Owner.
Some of them made business operation very easy, so I got some prize from company.
I always used "Inception Deck" that mentioned in the book "Agile Samurai",
And I also affected by Jeff Patton's "Product Discovery" way.
|September 2014-Now||Acting as a Scrum Master
I am acting as a Scrum Master of 2 different teams now.
One is continously data warehouse team.
Another one is Managing API team.
Both members are very very great.
Currently Sendai, Tokyo, and Osaka are all adopted Scrum. But not all can make good progress.
So sometimes I am acting as a Scrum Master of 3region.
