Tomasz en quelques mots
Hey there 🙋♂️
I am a Data Analyst and Data Visualisation Expert with board level experience.
I help companies take better decisions by leveraging the power of data.
My expertise ranges from Analytics Engineering (data modelling optimization), Data Analysis (with SQL queries and Python), to Data Visualisation (setting-up of relevant and to-the-point reports and dashboards to key stakeholders) and presentation of key insights.
I mainly work with the following tools:
- Data Analysis: SQL, Python
- Data modelling: DBT
- Data Visualisation: Power BI, Tableau, Google Data Studio, Looker
- Process automation with no-code: Zapier, Make
- Web Analytics: Google Analytics
In addition to my analytical skills, my past experiences as business analyst and Sales & Marketing professional in various industries (B2B textile, B2C e-commerce and digital marketplace in a startup environment) help me build a strong business acumen and become a real team-player.
Curious and open-minded, I am always on the look-out for the latest data trends and best practices.
