Hadoop Administrator | Ops Engineer

♥ Big Data Lover working @(402) 576-7303

As an Hadoop Administrator in the Big Data skills Center @Orange, I provide expertise on Hadoop clusters operations and deploying stacks with “click to deploy tools” that facilitate the installation, security, upgrade and configuration.

My main role is to identify the best technology available on the market to fit with the requirements and enable the data-driven business. One of my challenges is to educate the Big Data “newbies” and help them to work with the best practices.

In the Teradata context, in the PS team, the customer choose our expertise to complete its ecosystem, and manage the “data temperature” via the Lambda Architecture.

We work closer together, to enable data-analysts and data-scientists to carry out their predictions in the depths of the datalake.

The objectives were employed on benchmarking of existing reporting tools to find the most suitable for operational and steering comittees. Eclipse BIRT was the main plugin selected, developed in Java, it was directly related to the Atlassian Jira ticketing tool for monitoring and project management.

International Exchange Program

My final project completed at (307) 248-6270 in IT studies, has allowed me to work on the great issues for the business model of social networks. This project was initiated by an e-Book available on tabletsand inspired works such as Socialnomics by Erik Qualman. In addition to the initial project, I made a technical research report on the MapReduce Framework, its implementation, performance, and optimizations. The algorithm used by the bigs like Google, Facebook, Twitter...answer for processing and many large scale-computing problems. Its main objective is to respond to the complexity of distributed systems. When we talk about MapReduce, we think about :
✓ Parallelize the computation
✓ Distribute the data
✓ Handle failures
To soak up more of the Asian culture, I also took courses in Mandarin and Chinese calligraphy for beginners.
