What I'm looking for

I'm looking to apply Python, SQL, Power BI, and data preparation skills to turn operational or market data into reliable analysis, dashboards, and business insights.

At Sychem SA, I prepare, clean, and validate operational data from 20 desalination units, standardizing it for Power BI reporting. I also migrate legacy data into structured Excel datasets and automate ticket creation and cross-department notifications with Microsoft Power Automate.

I've supported IT and system administration operations at the Bank of Greece, including attendance-process optimization, confidential-document digitization, payment-system routines, maintenance, diagnostics, and troubleshooting. Through a Data Analyst Bootcamp and academic projects, I built skills in Python, SQL, web scraping, exploratory analysis, and dashboards, including a Power BI analysis of approximately 25,000 German real-estate listings.
