About

I'm an early-career Data Engineer based in Tampere, Finland, currently completing an MSc in Computer Science & Electrical Engineering at Tampere University.

I enjoy building data pipelines that are clean, reliable, and useful — from raw data ingestion to transformation, storage, and analysis.

Currently focused on:

  • Batch and streaming pipelines with PySpark
  • Data lake formats such as Delta Lake and Parquet
  • Workflow orchestration with Airflow
  • Databricks-based data engineering projects
  • Writing cleaner, more testable data code

Tech Stack

Languages: Python · SQL · Java
Data Engineering: PySpark · Spark Structured Streaming · ETL/ELT · Delta Lake · Parquet · Airflow · dbt
Platforms & Tools: Databricks · Azure Blob Storage · Docker · Git · PostgreSQL · MySQL

Featured Projects

Delta Data Formats Benchmarking

Benchmarked CSV, Parquet, and Delta Lake using PySpark and Databricks, comparing storage format behavior, query performance, and schema evolution.

Tech: PySpark · Delta Lake · Databricks · Azure Blob Storage

Structured Streaming + ML Pipeline

Built a PySpark pipeline combining structured streaming with machine learning to process and analyze retail sales data.

Tech: PySpark · Spark Structured Streaming · Python

Weather Analytics Pipeline

Built a production-inspired pipeline that ingests weather data from the Open-Meteo API, orchestrates ETL workflows with Airflow, and models it into a star schema in PostgreSQL for analytics.

Tech: Python · Apache Airflow · PostgreSQL · dimensional modeling
