PROFESSIONAL EXPERIENCE

Confidential, Austin

Responsibilities:

• DB2 SQL Procedures and UNIX Shell Scripts were designed and developed for Data Import/Export and Conversions.
• A Django dashboard wif custom look and feel for end user TEMPhas been created after a careful study of teh Django admin site and dashboard.
• Unit Test Python library was used for testing many programs on python and other codes.
• Worked on selenium testing framework.
• JIRA was used to build an environment for development.
• Assisted in reduction of cost and optimization of supplier selection for teh CRM Applications.
• Ensured high quality data collection and maintaining teh integrity of teh data.
• Cleaned data and processed third party spending data into maneuverable deliverables wifin specific formats wif Excel macros andpythonlibraries.
• Used several python libraries like wxPython, numPY and matPlotLib.
• Was involved in environment, code installation as well as teh SVN implementation, Saas.
• Build all database mapping classes using Django models and Cassandra.
• Used Pandas API to put teh data as time series and tabular format for east timestamp data manipulation and retrieval.
• Only free and open source time series databases and their features have been compared. Therefore if someone asks “have you tried Kdb+ orInformix?” teh answer will be no. They are probably awesome though.
• Teh list will only include databases that either classify themselves in their marketing material as time series, or have been written about in a blog by a cool company as something they are using for time series data.
• me’m only going to accept additional suggestions thatchangethe top 10 if they are actually useful wifin teh context of this blog post. This means they ca handle hundreds of thousands of writes per second wif reasonable query performance and have a data model that includes labels.
• Databases built from teh ground up for time series data are significantly faster than those that sit on top of non purpose built databases like Riak KV, Cassandra and Hadoop.
• Performing queries across billions of metrics looking for labels that only match a few of them (a common scenario wif time series data at scale) is really slow in Cassandra. This is coz of teh way it stores data in columns. This extends to any columnar database including Google's Big Query which all have a natural disadvantage wif time series data.
• Storage efficiency is extremely important. Teh purpose built TSDB's only consume a few bytes of storage per data point. Why this is important becomes clear when you start to add up teh costs.
• Designed and developed data management system using MySQL.
• Working wif data transformations Big Data from HDFS, HIVE, HBASE and MySQL and Pig.
• Automating teh data operations using Oozie and analyzing teh data by performing Hive Queries.
