Data Analyst combining a business-analysis background with hands-on technical skills in SQL, Python, and Tableau. After several years as a System Business Analyst at a TOP 2 Eastern European ERP provider — working with enterprise data, stakeholder requirements, and large-scale B2B systems — relocated to Israel, completed an MBA at Ariel University, and shifted focus to data analytics. Brings the full toolkit to turn raw data into decisions — SQL for extraction and analysis, Python and pandas for transformation, dbt and Docker for pipeline engineering, and Tableau for dashboards that stakeholders actually use.

Data Engineer / Data Analyst at SELF-EMPLOYED (2025-01 – Present)

Developed several data projects independently; below is the most comprehensive one, "Taxi Data Pipeline" — an end-to-end pipeline from raw data to dashboards:

• consolidated 3.7M rows of raw taxi trip data from Parquet and CSV sources into a structured staging layer, to enable reliable downstream processing, by building a Python and Pandas extraction pipeline into PostgreSQL
• transformed raw staging data into a star schema (5 dimension tables and 1 fact table), to support consistent analytical reporting, by designing the DWH structure in dbdiagram.io and building a PostgreSQL warehouse with dbt
• moved modeled DWH data into the ClickHouse layer, to make it available for fast, large-scale analytical queries, by building a Python and Pandas pipeline that reads from PostgreSQL and loads into ClickHouse
• structured the ClickHouse layer into 3 data marts, to align it with key reporting needs, by organizing tables around core business entities
• built 2 interactive Tableau dashboards, to visualize key metrics and trends for end users, using calculated fields, parameters, and LOD expressions
• containerized the entire pipeline with Docker and version-controlled it with Git, to ensure full reproducibility for anyone running the project
