Service Description

I have extensive experience in data warehousing and analytics as well as business intelligence using a variety of tools including Hadoop, Greenplum, MonetDB, Tableau, BIRT, and Pentaho Kettle. I've implemented data processing techniques across various levels of abstraction, from writing my own map reduce processes in Java, with Hadoop streaming, as well as higher level tools such as Hive and Pig.

I have worked with multi-terabyte data warehouses as well as high traffic OLTP databases. I implemented these both in AWS EC2 with S3 as well as on bare metal. My past experience involved architecting both relational and non-relation databases using MySQL, PostgreSQL, MongoDB, and HBase. I've implemented caching systems with memcached and ehcache. From past experience I've learned to ensure consistency and durability where it is needed. It is important to balance cost, performance, and data integrity.

I am also a skilled programmer in Java and Python. My work in the past included examining code in multiple languages for scalability concerns. Linux has always been one of my strengths. I have used it since Red Hat Linux 5.1 and currently use Linux exclusively for my personal use, as well as for the vast majority of my work.

I look forward to working on your most challenging problems, and I enjoy engineering solutions to scale to match your needs.
