Oleksandr Landar
Data Analyst
As a sales manager, I regularly analyzed behavior and data. I used
Excel daily and found it to be an essential tool. High performance
has always been a priority for me, which led me to explore computer
science as a way to accelerate progress and maximize output.
I made the most of my time at "Soft Serve," absorbing knowledge
about the business processes of a large tech company and learning
coding and various tools. A friend of mine, a data engineer,
eventually influenced my decision to link my future with data by
transitioning into data analysis with a technical focus. A data
analyst is one of the key roles in any company, requiring both a deep
CONTACTS understanding of the business domain and proficiency in technical
tools.
