About Me

My story

I’m working in Data Processing and Analysing using big data technologies tools, recently at the Internal Security Forces (ISF) in Lebanon.

In this position, I work on collecting data from various sources, pre-processing / processing it, cleansing it, and putting it into Hadoop (Data Lake), as well as analysing clients' use cases, querying the data required, and then putting it into Elasticsearch to be visualised using tools on top of it like Kibana and Siren and many others

Besides, I’m responsible for modelling application system models, I analyse user/business system requirements and respond to outages as well as contribute to all phases of the software development lifecycle.

Additionally, I work on testing and debugging programs to meet business needs, as well as dealing with and occasionally directing third-party partners to help achieve business and technology initiatives.
