Data Engineer
CognitiveCredit.
As a Data Engineer at Cognitive Credit I've been responsible for the transformation and flow of data throughout the different
stages of our pipeline. From parsing the components' input, to writing scripts that incorporate financial accounting logic and pushing the output in the database, I've been exposed to a variety of challenges whilst working with data. The tech stack is
Python, NodeJS, PostgreSQL and a significant amount of Bash. I get to have some exposure to AWS, Docker and Jenkins,
all being used for running the pipeline.
• Created, maintained and improved the database schema
• Created a variety of ETL tools with Python and Bash/PSQL
• A significant part of my job was text interpretation with regular expressions
• Written automated tools to migrate processes from the hands of developers (our team) to analysts
• Incorporated processes that would freeze the data in place once signed-off so as to make it resilient to regressions
introduced by the development of our code base.

Graduate Business Analyst - Technical
PredictX.
Working as a technical business analyst, I used various tools such as Python, Knime and Omniscope. My work at PredictX
can be summarized as follows:
• Created reports with the Omniscope BI tool.
• Developed clients' data model by building a relational schema from their existing data sources. Achieved
optimization through denormalisation for ease of reporting.
• Developed clients' backend by building a graph model with each node representing a SQL script of a database
object.
• The graph data structure showed objects' dependencies and allowed me to build independent objects in simultaneously, in parallel with Joblib.
• Developed a "deltas process" through which clients can track changes in objects, since each object represented a
snapshot of their business at a point in time (slowly changing dimensions).
• Created a SQL template engine to build dynamic SQL queries that could be pushed to Vectorwise through Python.
