About

My name is Brian Jarrett. This is my tech blog.

I’ve been working professionally with data since I got into IT in late 2000. I ended up in data warehousing by a coin toss really. After my first IT job interview they asked me to choose a position…working on one of the companies homegrown apps or the data warehouse. I had no idea what to choose, but I thought warehousing sounded like something cool, so I chose it.

More than twenty years later, I’m still doing data warehousing. It’s changed shape over the years, with new technologies, cheap storage, and increased processing power, but at its core it’s still all just data management.

I started out hand-coding ETL in an existing data warehouse in Informix 4GL. Then I moved to coding in Perl, then several ETL tools. I’ve used all kinds of databases, including all the big players in the space.

I learned how to build semantic layers. I also picked up some experience with reporting tools along the way.

These days, I mostly work as a data architect, although I still do a lot of ETL and semantic layer work. I modeled my first data “mart” back in 2004. In 2005 I built a data warehouse for a printing company. In 2008 I went to work for a cable company and spent nearly nine years designing and building out a large-scale data warehouse.

In 2017 I built an entire data platform for a credit card processing company. This system included not only an EDW, but also an automated, config-driven, near-real time ODS layer, an entire chunk of company data I’d never concerned myself with before. The role of the data architect has evolved now to encompass all kinds of data, even that ¬†formerly outside of the monolithic data warehouse.

These days, I’m maintaining the system I built while planning for the future on a petabyte-scale MPP platform, all 100% cloud-native.

So have a look around the site. It’s pretty new still, but more content is forthcoming.

See you around.
