About Anatoliy
Data Extraction/ETL | Neos Flow, Process Infographics, ETL Pipeline
Kyiv, Ukraine - 8:13 am local time
My Tech Stack: SQL (Vertica), Python (Pandas, NumPy, Matplotlib), Tableau, Power BI.
I have experience in both full-time roles and ad-hoc business problem solving — ranging from optimizing analytical scripts to deploying and troubleshooting complex aggregations in Tableau dashboards. Thanks to my background in the performing arts industry and teaching, I don't just crunch numbers; I effectively "translate" complex technical metrics into clear, actionable language for business teams and clients.
I am looking for part-time projects or contract-based work. I would be happy to discuss how I can bring value to your team!
